Environmental Justice 2023 Set is comprised of two layers: Environmental Justice Block Groups 2023 and Environmental Justice Distressed Municipality 2023. All Census and ACS data used in the creation of these data are the latest available from the Census at time of calculation.
Environmental Justice Block Groups 2023 was created from Connecticut block group boundary data located in the Census Bureau's 2022 Block Group TIGER/Line Shapefiles. The poverty data used to determine which block groups qualified as EJ communities (see CT State statute 22a-20a) was based on the Census Bureau's 2021 ACS 5-year estimate. This poverty data was joined with the block group boundaries in ArcPro. Block groups in which the percent of the population below 200% of the federal poverty level was greater than or equal to 30.0 were selected and the resulting selection was exported as a new shapefile. The block groups were then clipped so that only those block groups outside of distressed municipalities were displayed.
Maintenance – This layer will be updated annually and will coincide with the annual distressed municipalities update (around August/September). The latest ACS 5-year estimate data should be used to update this layer.
Environmental Justice Distressed Municipalities 2023 was created from the Connecticut town boundary data located in the Census Bureau's 2022 TIGER/Line Shapefiles (County Subdivisions). From this shapefile, "select by attribute" was used to select the distressed municipalities by town name (note: the list of 2023 distressed municipalities was provided by the CT Department of Economic and Community Development). The selection was then exported a new shapefile. The “Union” tool was used to unite the new shapefile with tribal lands (American Indian Area Geography) boundary data from the 2020 TIGER/Line files. In the resulting layer, the tribal lands were deleted so only the distressed municipalities remained. Maintenance – This layer will be updated annually when the DECD produces its new list of distressed municipalities (around August/September).
Note: A distressed municipality, as designated by the Connecticut Department of Economic and Community Development, includes municipalities that no longer meet the threshold requirements but are still in a 5-year grace period. (See definition at CGS Sec. 32-9p(b).) Fitting into that grace period, ten towns continue to be eligible for distressed municipality benefits because they dropped off the list within the last five years. Those are Bristol, Enfield, Groton, Killingly, Naugatuck, New Haven, North Stonington, Plainfield, Preston, and Stratford.

These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of \"farmed wetlands\" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.
Department of Transportation (DOT) Scenic Land Strips contains parcels, generally long narrow strips of land, that were purchased by the DOT under the Federal Highway Beautification Act of 1965. The purpose of this program was to reduce the proliferation of billboards and other unsightly structures or facilities along federally designated highways. There are 33 parcels of land located along seven highways in eight towns.
Highways and the corresponding towns where DOT Scenic Lands are located include:
Cold water habitat was determined using available fish and\nwater temperature data collected by the Connecticut Department of Energy and\nEnvironmental Protection (CT DEEP) Monitoring and Assessment, Inland Fisheries\nand Volunteer Stream Temperature Programs. The analysis to date includes years\n1988 - 2023. The mapping application will be updated with new or updated\ninformation as it is collected, quality assured and analyzed. CT DEEP has a\nrobust data set of stream fish community and temperature logger data dating\nback to the late 1980's. In previous work (Beauchene et al., 2014) these data\nwere used to develop cold water temperature metrics and fish species that were\nindicators of cold-water habitat. With the knowledge gained from the\ncompilation of recent Connecticut based studies, identification and subsequent\nclassification of cold-water habitat can be made with data from either fish or\nstream water temperature. To catalog cold water habitat CT DEEP analyzed all\navailable fish and water temperature data collected in accordance to standard\noperating procedures to identify cold water rivers and streams. The analysis to\ndate includes years 1988 – 2023 and identified 1,716 samples and 792 sites\nindicating cold water habitat from both fish community and temperature logger\ndata. If a site was measured to have\ncold water habitat with either fish community or water temperature using the\nJune-August metric at any time during our surveys, it was considered cold water\nstream habitat.

The map was compiled from a geospatial analysis of the surficial materials and thickness of glacial sediments digital data layers of the Surficial Materials Map of Connecticut, Stone and others (1992) and Quaternary Geologic Map of Connecticut and The Long Island Sound Basin, Stone and others (1998, 2005). The map identifies areas with greater potential for ground water development based upon the texture and thickness of surficial aquifer deposits. The resulting hydrostratigraphic units define areas of coarse grained deposits, coarse overlying fine grained deposits, fine grained deposits, and areas where fine grained deposits overly coarse grained deposits. Aquifer deposit thickness intervals are 1-50 feet, 50-100 feet, 100-200 feet, 200-300 feet, and 300-400 feet.\n\nThe Surficial Aquifer Potential Map was prepared by the Connecticut Geological Survey at the request of the Water Protection and Land Reuse Bureau of the Department of Environmental Protection. A statewide view of surficial aquifer resources is necessary to facilitate proactive aquifer protection and water supply planning. Previous statewide groundwater availability (Meade 1978) and ground water yields mapping (Mazzaferro 1986) provided excellent planning documents at the time of publication.

It also includes data from the Sewer Service Area 2018 file in areas where the OPM dataset was not as current.Submission of Tier II form is required under Section 312 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA). The purpose of this form is to provide state, tribal, and local officials, and the public with specific information on potential hazards. This includes the locations, as well as the amount, of hazardous chemicals present at facilities during the previous calendar year.
DEEP does not guarantee that this information is complete and/or free from erroneous entries. This information is updated annually based on Tier II reporting by facilities and businesses that possess inventories of substances or products that meet or exceed reporting thresholds.
Environmental Justice Block Groups 2022 was created from\nConnecticut block group boundary data located in the Census Bureau's 2020\nTIGER/Line Shapefiles. The poverty data used to determine which block groups\nqualified as EJ communities (see CT State statute 22a-20a) was based on the\nCensus Bureau's 2020 ACS 5-year estimate. This poverty data was joined with the\nblock group boundaries in ArcPro. Block groups in which the percent of the\npopulation below 200% of the federal poverty level was greater than or equal to\n30.0 were selected and the resulting selection was exported as a new shapefile.\nThe block groups were then clipped so that only those block groups outside of\ndistressed municipalities were displayed. Maintenance – This layer will be\nupdated annually and will coincide with the annual distressed municipalities\nupdate (around August/September). The latest ACS 5-year estimate data should be\nused to update this layer. Environmental Justice Distressed Municipalities 2020\nwas created from Connecticut town boundary data located in the Census Bureau's\n2020 TIGER/Line Shapefiles (County Subdivisions).
\n\nFrom this shapefile, "select by attribute" was used to\nselect the distressed municipalities by town name (note: the list of 2022\ndistressed municipalities was provided by the CT Department of Economic and\nCommunity Development). The selection was then exported a new shapefile. The\n“Union” tool was used to unite the new shapefile with tribal lands (American\nIndian Area Geography) boundary data from the 2020 TIGER/Line files. In the\nresulting layer, the tribal lands were deleted so only the distressed\nmunicipalities remained. Maintenance – This layer will be updated annually when\nthe DECD produces its new list of distressed municipalities (around\nAugust/September).
\n\nNote: A distressed municipality, as designated by the\nConnecticut Department of Economic and Community Development, includes\nmunicipalities that no longer meet the threshold requirements but are still in\na 5-year grace period. (See definition at CGS Sec. 32-9p(b).)

tank followed by a leaching system, any necessary pumps and siphons, and a
groundwater control system upon which the operation of the leaching system
depends. This interpretation focuses mainly on the septic tank leaching field
and groundwater control system Soil Potential Ratings Soil potential ratings
indicate the relative quality of a soil for a particular use compared to other
soils in a given area, in this case the State of Connecticut.
The rating criteria were developed by a committee of State and local
sanitarians, engineers, and installers. The soils data was provided by
the USDA Natural Resources Conservation Service (NRCS), and the performance
and site conditions for a typical system were defined. This information
provided a standard against which various combinations of properties of
soils within Connecticut could be compared.
The engineering and installation practices used to overcome various soil
limitations were listed, and their costs estimated. This information was
used to identify limitations and costs associated with installing an SSDS
on each soil in Connecticut. Soils with no or minor limitations for the
installation of an SSDS were rated the highest. Conversely, soils requiring
extensive site modification and design were rated the lowest. The ease of
system installation, and therefore cost, formed the basis of the rating scheme.
Rating Classes
The rating class definitions refer to installation of an SSDS that meets
State and local health code regulations. Soils with high potential have
characteristics that meet the performance standard. A typical system can
be installed at a cost of "x", which represents the going rate for installing
an SSDS. The actual value of x varies depending upon many factors unrelated
to soil properties.
The cost of installing a leaching field is expressed as a multiple of x and
called the cost factor. For example, a cost factor of 3x to and 3.5x means
that the estimated cost of installing a leaching field in the particular
soil ranges from 3 to 3.5 times more than that of installing a field in a
soil with high potential. The cost factors provide relative estimates of
the costs of installing an SSDS.
The soil potential ratings and associated cost factors, assuming a typical
system, are defined below.
High Potential - These soils have the best combination of characteristics
or have limitations that can be easily overcome using standard installation practices.
The cost factor is 1x to 2.0x.
Medium Potential - These soils have significant limitations, such as low
percolation rate, that generally can be overcome using commonly applied designs.
The cost factor ranges from 2.0x to 2.5x.
Low Potential - These soils have one or more limitations, such as low percolation
rate and depth to seasonal high water table, that require extensive design and
site preparation to overcome. The cost factor ranges from 2.5x to 3.5x.
Very Low Potential - These soils have major soil limitations, such as depth to
bedrock, that require extensive design and site preparation to overcome. A permit
for an SSDS may not be issued unless the naturally occurring soils meet the minimal
requirements outlined in the State health code. It is unlikely that these soils
can be improved sufficiently to meet State health code regulations. The cost factor
ranges from 4.25x to 6.0x.
Extremely Low Potential - These soils have multiple major limitations, such as
flooding and depth to seasonal high water table, which are extremely difficult
to overcome. A permit for an SSDS may not be issued unless the naturally occurring
soils meet the minimal requirements outlined in the State health code. It is
unlikely that these soils can be improved sufficiently to meet State health code
regulations.
Not Rated - Areas labeled Not Rated have soil characteristics that show extreme
variability from one location to another. The work needed to overcome adverse soil
properties cannot be estimated. These areas commonly are urban land complexes or
miscellaneous areas. An on-site investigation is required to determine soil
conditions at the site.
This data set is a digital soil survey and generally is the most
detailed level of soil geographic data developed by the National
Cooperative Soil Survey. The information was prepared by digitizing
maps, by compiling information onto a planimetric correct base
and digitizing, or by revising digitized maps using remotely
sensed and other information.
This data set consists of georeferenced digital map data and
computerized attribute data. The map data are in a soil survey area
extent format and include a detailed, field verified inventory
of soils and miscellaneous areas that normally occur in a repeatable
pattern on the landscape and that can be cartographically shown at
the scale mapped. The soil map units are linked to attributes in the
National Soil Information System relational database, which gives
the proportionate extent of the component soils and their properties.

Parent material name is a term for the general physical, chemical,
and mineralogical composition of the unconsolidated material, mineral
or organic, in which the soil forms. Mode of deposition and/or weathering
may be implied by the name.
The soil surveyor uses parent material to develop a model used for soil
mapping. Soil scientists and specialists in other disciplines use parent
material to help interpret soil boundaries and project performance of
the material below the soil. Many soil properties relate to parent material.
Among these properties are proportions of sand, silt, and clay; chemical
content; bulk density; structure; and the kinds and amounts of rock fragments.
These properties affect interpretations and may be criteria used to separate
soil series. Soil properties and landscape information may imply the kind of
parent material.
For each soil in the database, one or more parent materials may be identified.
One is marked as the representative or most commonly occurring.The representative
parent material name is presented here.

soils to include any of the soil types designated as poorly drained,
very poorly drained, alluvial, or floodplain by the National Cooperative Soil Survey,
as may be periodically amended, of the Natural Resources Conservation Service
of the United States Department of Agriculture.
Map units dominated by Connecticut inland wetland soils may have inclusions
of non-wetland soils, and non-wetland map units may have inclusions of
Connecticut inland wetland soils. On site investigation is necessary to
determine the presence or absence of wetland soils in a particular area.

This rating indicates the percentage of map units that meets the criteria
for hydric soils. Map units are composed of one or more map unit components
or soil types, each of which is rated as hydric soil or not hydric. Map units
that are made up dominantly of hydric soils may have small areas of minor
nonhydric components in the higher positions on the landform, and map units
that are made up dominantly of nonhydric soils may have small areas of minor
hydric components in the lower positions on the landform. Each map unit is
rated based on its respective components and the percentage of each component
within the map unit.
The thematic map is color coded based on the composition of hydric components.
The five color classes are separated as 100 percent hydric components, 66 to
99 percent hydric components, 33 to 65 percent hydric components, 1 to 32 percent
hydric components, and less than one percent hydric components.
In Web Soil Survey, the Summary by Map Unit table that is displayed below the
map pane contains a column named 'Rating'.In this column the percentage of each
map unit that is classified as hydric is displayed.
Hydric soils are defined by the National Technical Committee for Hydric Soils (NTCHS)
as soils that formed under conditions of saturation, flooding, or ponding long enough
during the growing season to develop anaerobic conditions in the upper part (Federal
Register, 1994). Under natural conditions, these soils are either saturated or
inundated long enough during the growing season to support the growth and reproduction
of hydrophytic vegetation.
The NTCHS definition identifies general soil properties that are associated with
wetness. In order to determine whether a specific soil is a hydric soil or nonhydric
soil, however, more specific information, such as information about the depth and
duration of the water table, is needed. Thus, criteria that identify those estimated
soil properties unique to hydric soils have been established (Federal Register, 2002).
These criteria are used to identify map unit components that normally are associated
with wetlands. The criteria used are selected estimated soil properties that are
described in \"Soil Taxonomy\" (Soil Survey Staff, 1999) and \"Keys to Soil Taxonomy\"
(Soil Survey Staff, 2006) and in the \"Soil Survey Manual\" (Soil Survey Division Staff, 1993).
If soils are wet enough for a long enough period of time to be considered hydric,
they should exhibit certain properties that can be easily observed in the field.
These visible properties are indicators of hydric soils. The indicators used to make
onsite determinations of hydric soils are specified in \"Field Indicators of Hydric
Soils in the United States\" (Hurt and Vasilas, 2006).

Farmland classification identifies map units as prime farmland,
farmland of statewide importance, farmland of local importance,
or unique farmland. It identifies the location and extent of the
soils that are best suited to food, feed, fiber, forage, and
oilseed crops. NRCS policy and procedures on prime and unique
farmlands are published in the \"Federal Register,\" Vol. 43,
No. 21, January 31, 1978.

Drainage class (natural)\" refers to the frequency and duration of wet periods
under conditions similar to those under which the soil formed. Alterations of
the water regime by human activities, either through drainage or irrigation,
are not a consideration unless they have significantly changed the morphology
of the soil. Seven classes of natural soil drainage are recognized-excessively
drained, somewhat excessively drained, well drained, moderately well drained,
somewhat poorly drained, poorly drained, and very poorly drained. These classes
are defined in the \"Soil Survey Manual.
The State of Connecticut defines inland wetlands based on soils.
The Connecticut Inland Wetlands and Watercourses Act defines wetland
soils to include any of the soil types designated as poorly drained,

This assessment is based on\ninformation collected and compiled prior to 2022. It represents conditions at a\nparticular point in time and does not represent current conditions. Depending\non the type of waterbody - river, lake, or estuary - this information\ngeographically displays attainment and non-attainment (e.g. full supporting,\nnot supporting, not assessed) for each designated use - aquatic life, marine\naquatic life, recreation use, fish consumption, shellfish harvesting, and\ndrinking water supply.

Connecticut 305(b) Assessed Waters files includes rivers, lakes and estuaries that have been assessed in compliance with Sections 305(b) and 303(d) of the federal Clean Water Act. Section 305(b) of the Clean Water Act requires each state to monitor, assess and report on the quality of its waters relative to attainment of designated uses established by the State's water quality standards. Section 303(d) requires each State to compile a subset of that list identifying only those waters not meeting water quality standards and assign a Total Maximum Daily Load (TMDL) priority ranking to each impaired waterbody.
This assessment is based on information collected and compiled prior to 2016. It represents conditions at a particular point in time and does not represent current conditions. Depending on the type of waterbody - river, lake, or estuary - this information geographically displays attainment and non-attainment (e.g. full supporting, not supporting, not assessed) for each designated use - aquatic life, marine aquatic life, recreation use, fish consumption, shellfish harvesting, and drinking water supply.

Section 303(d) requires each State to compile a subset of that list identifying only those waters not meeting water quality standards and assign a Total Maximum Daily Load (TMDL) priority ranking to each impaired waterbody.
This assessment is based on information collected and compiled prior to 2012. It represents conditions at a particular point in time and does not represent current conditions. Depending on the type of waterbody - river, lake, or estuary - this information geographically displays attainment and non-attainment (e.g. full supporting, not supporting, not assessed) for each designated use - aquatic life, marine aquatic life, recreation use, fish consumption, shellfish harvesting, and drinking water supply.

Connecticut 305(b) Assessed Waters files includes rivers, lakes and estuaries that have been assessed in compliance with Sections 305(b) and 303(d) of the federal Clean Water Act. Section 305(b) of the Clean Water Act requires each state to monitor, assess and report on the quality of its waters relative to attainment of designated uses established by the State's water quality standards. Section 303(d) requires each State to compile a subset of that list identifying only those waters not meeting water quality standards and assign a Total Maximum Daily Load (TMDL) priority ranking to each impaired waterbody.
This assessment is based on information collected and compiled prior to 2006. It represents conditions at a particular point in time and does not represent current conditions. Depending on the type of waterbody - river, lake, or estuary - this information geographically displays attainment and non-attainment (e.g. full supporting, not supporting, not assessed) for each designated use - aquatic life, marine aquatic life, recreation use, fish consumption, shellfish harvesting, and drinking water supply.

Ground Waters means waters flowing through earth materials beneath the ground surface and the Ground Water Quality Classifications is a designation of the use of the ground waters. The Ground Water Quality Classifications is based primarily on the Adopted Water Quality Classifications Map sheets with information collected and compiled from 1986 to 1997 by major drainage basin. The maps were hand-drawn at 1:50,000-scale in ink on Mylar which had been underprinted with a USGS topographic map base. The digital layer includes ground water water quality classifications. It does not include water quality classifications for ground waters below surface waterbodies. Surface Water Quality Classifications are defined separately in a set of data layers comprised of line and polygon features. The Ground Water Quality Classifications and the Surface Water Quality Classifications are usually presented together as a depiction of water quality classifications in Connecticut. The Ground Water Quality Classes are GA, GAA, GAAs, GB and GC. Classes GAA and GA designate areas of existing or potential drinking water. All ground waters not otherwise classified are considered as Class GA. Class GAAs is for ground water that is tributary to a public water supply reservoir. Class GB is used where ground water is not suitable for drinking water. Class GC is used for assimilation of permitted discharges. Modified classes GA-Impaired, GAA-Impaired, GAA-Well-Impaired, GAA-Well and GA-NY are found in the data layer to categorize special cases of GA or GAA that may not be meeting the goal (impaired), surround public water supply wells (Well) or contribute to a public water supply watershed for another state (NY).\nThere are three elements that make up the Water Quality Standards which is an important element in Connecticut's clean water program. The first of these is the Standards themselves. The Standards set an overall policy for management of water quality in accordance with the directive of Section 22a-426 of the Connecticut General Statutes. In simple terms the policies can be summarized by saying that the Department of Energy and Environmental Protection shall: Protect surface and ground waters from degradation, Segregate waters used for drinking from those that play a role in waste assimilation, Restore surface waters that have been used for waste assimilation to conditions suitable for fishing and swimming, Restore degraded ground water to protect existing and designated uses, Provide a framework for establishing priorities for pollution abatement and State funding for clean up, Adopt standards that promote the State's economy in harmony with the environment. The second element is the Criteria, the descriptive and numerical standards that describe the allowable parameters and goals for the various water quality classifications. The final element is the Classification Maps that show the Class assigned to each surface and groundwater resource throughout the State. These maps also show the goals for the water resources, and in that manner provide a blueprint and set of priorities for Connecticut's efforts to restore water quality. Although federal law requires adoption of Water Quality Standards for surface waters, Water Quality Standards for ground waters are not subject to federal review and approval. Connecticut's Standards recognize that surface and ground waters are interrelated and address the issue of competing use of ground waters for drinking and for waste water assimilation. These Standards specifically identify ground water quality goals, designated uses and those measures necessary for protection of public and private drinking water supplies; the principal use of Connecticut ground waters. These three elements comprise the Water Quality Standards and are adopted using the public participation procedures contained in Section 22a-426 of the Connecticut General Statutes. The Standards, Criteria and Maps are reviewed and revised roughly every three years. Any change is considered a revision requiring public participation. The public participation process consists of public meetings held at various locations around the State, notification of all chief elected officials, notice in the Connecticut Law Journal and a public hearing. The Classification Maps are the subject of separate public hearings which are held for the adoption of the map covering each major drainage basin in the State. The Water Quality Standards and Criteria documents are available on the DEEP website, www.ct.gov/deep.\nThe Ground and Surface Water Quality Classifications do not represent conditions at any one particular point in time. During the conversion from a manually maintained to a digitally maintained statewide data layer the Housatonic River and Southwest Coastal Basins information was updated. The publication date of the digital data reflects the official adoption date of the most recent Water Quality Classifications. Within the data layer the adoption dates are: Housatonic and Southwest Basins - March 1999, Connecticut and South Central Basins - February 1993, Thames and Southeast Basins - December 1986.

Due to the presence of 3 distinct Canada goose populations in Connecticut, the Atlantic Population (AP), North Atlantic Population (NAP), and Atlantic Flyway Resident Population (AFRP), the state has been divided into 3 goose hunting zones, each with different regulations, based on the status of the population and the overall management goal for each population. Refer to the current Connecticut Migratory Bird Hunting Guide and the Hunting page on the DEEP website for the most up to date information on all public hunting areas, waterfowl closure areas, regulations, licenses, stamps, timing and bag limits. The boundaries represented in this data are approximate. For a list of migrant goose zones explained by town and by street, visit https://portal.ct.gov/deep/hunting/public-hunting-areas#GooseZones . Waterfowl regulations may include additional designations, such as the North Zone: The portion of the state north of Interstate 95; South Zone: The portion of the state south of Interstate 95.

The State of Connecticut Stream Flow Standards and Regulations (Section 26-141b-1 to 26-141b-8 of the Regulations of Connecticut State Agencies) define four stream flow class standards:
Class 1 is described as a free flowing stream
Class 2 is described as minimally altered stream flow
Class 3 is described as moderately altered stream flow
Class 4 is described as substantially altered stream flow
The regulations include consideration of 18 factors related to the degree of alteration in stream flow when adopting river or stream system classifications. Spatial data for each of the factors was gathered from a variety of best available sources. These sources were available at varying scales. A methodology was developed to consider all 18 factors and determine the class for a particular stream segment. In addition, public comment was solicited and considered to identify the final stream flow classification.
For additional information on the classification process, see Section 26-141b-5 RCSA Adoption of river or stream system classifications, Fact Sheet for Stream Flow Classification Process under Section 26-141b-1 to 26-141b-8 of the Regulations of Connecticut State Agencies, Technical Support Document Methodology for Defining Preliminary Stream Flow Classification, and Final Stream Flow Classifications and Statement of Reasons Document. These documents can be found on the CT DEEP website at www.ct.gov/deep/streamflow.

Section 305(b) of the Clean Water Act requires each state to monitor, assess and report on the quality of its waters relative to attainment of designated uses established by the State's water quality standards. Section 303(d) requires each State to compile a subset of that list identifying only those waters not meeting water quality standards and assign a Total Maximum Daily Load (TMDL) priority ranking to each impaired waterbody.
This assessment is based on information collected and compiled prior to 2024. It represents conditions at a particular point in time and does not represent current conditions. Depending on the type of waterbody - river, lake, or estuary - this information geographically displays attainment and non-attainment (e.g. full supporting, not supporting, not assessed) for each designated use - aquatic life, marine aquatic life, recreation use, fish consumption, shellfish harvesting, and drinking water supply.

Environmental Justice 2025 Set is comprised of two layers: Environmental Justice Block Groups 2025 and Environmental Justice Distressed Municipality 2025. All Census and ACS data used in the creation of these data are the latest available from the Census at time of calculation.
Environmental Justice Block Groups 2025 was created from Connecticut block group boundary data located in the Census Bureau's 2025 Block Group TIGER/Line Shapefiles. The poverty data used to determine which block groups qualified as EJ communities (see CT State statute 22a-20a) was based on the Census Bureau's 2024 ACS 5-year estimate. This poverty data was joined with the block group boundaries in ArcPro. Block groups in which the percent of the population below 200% of the federal poverty level was greater than or equal to 30.0 were selected and the resulting selection was exported as a new shapefile. The block groups were then clipped so that only those block groups outside of distressed municipalities were displayed.
Maintenance – This layer will be updated annually and will coincide with the annual distressed municipalities update. The latest ACS 5-year estimate data should be used to update this layer.
Environmental Justice Distressed Municipalities 2025 was created from the Connecticut town boundary data located in the Census Bureau's 2025 TIGER/Line Shapefiles (County Subdivisions). From this shapefile, \"select by attribute\" was used to select the distressed municipalities by town name (note: the list of 2025 distressed municipalities was provided by the CT Department of Economic and Community Development). The selection was then exported a new shapefile. The “Union” tool was used to unite the new shapefile with tribal lands (American Indian Area Geography) boundary data from the 2025 TIGER/Line files. In the resulting layer, the tribal lands were deleted so only the distressed municipalities remained. Maintenance – This layer will be updated annually when the DECD produces its new list of distressed municipalities.
Note: A distressed municipality, as designated by the Connecticut Department of Economic and Community Development, includes municipalities that no longer meet the threshold requirements but are still in an eligibility grace period. (See definition at CGS Sec. 32-9p(b).) Fitting into that grace period, twelve towns continue to be eligible for distressed municipality benefits. Those are Ansonia, Bristol, Chaplin, Griswold, Groton, Montville, Naugatuck, New Haven, North Stonington, Preston, Stratford, Voluntown.

All Census and ACS data used in the creation of these data are the latest available from the Census at time of calculation.
Environmental Justice Block Groups 2023 was created from Connecticut block group boundary data located in the Census Bureau's 2022 Block Group TIGER/Line Shapefiles. The poverty data used to determine which block groups qualified as EJ communities (see CT State statute 22a-20a) was based on the Census Bureau's 2021 ACS 5-year estimate. This poverty data was joined with the block group boundaries in ArcPro. Block groups in which the percent of the population below 200% of the federal poverty level was greater than or equal to 30.0 were selected and the resulting selection was exported as a new shapefile. The block groups were then clipped so that only those block groups outside of distressed municipalities were displayed.
Maintenance – This layer will be updated annually and will coincide with the annual distressed municipalities update (around August/September). The latest ACS 5-year estimate data should be used to update this layer.
Environmental Justice Distressed Municipalities 2023 was created from the Connecticut town boundary data located in the Census Bureau's 2022 TIGER/Line Shapefiles (County Subdivisions). From this shapefile, "select by attribute" was used to select the distressed municipalities by town name (note: the list of 2023 distressed municipalities was provided by the CT Department of Economic and Community Development). The selection was then exported a new shapefile. The “Union” tool was used to unite the new shapefile with tribal lands (American Indian Area Geography) boundary data from the 2020 TIGER/Line files. In the resulting layer, the tribal lands were deleted so only the distressed municipalities remained. Maintenance – This layer will be updated annually when the DECD produces its new list of distressed municipalities (around August/September).
Note: A distressed municipality, as designated by the Connecticut Department of Economic and Community Development, includes municipalities that no longer meet the threshold requirements but are still in a 5-year grace period. (See definition at CGS Sec. 32-9p(b).) Fitting into that grace period, ten towns continue to be eligible for distressed municipality benefits because they dropped off the list within the last five years. Those are Bristol, Enfield, Groton, Killingly, Naugatuck, New Haven, North Stonington, Plainfield, Preston, and Stratford.
