EX PLANATIONW ATER Q UALITY CLAS S IFICATIONS (W Q C) MAPS are oneof the elements of the W ater Q uality S tandards (W Q S ) for theS tate of Connecticut. The W Q S are a part of Connecticut's cleanw ater program and are essential for protecting and improving waterquality. The W Q S follow the principles of Connecticut's CleanW ater Act which is in Chapter 446K of the Connecticut GeneralS tatutes. The W Q S provide policy guidance in many areas, forexample decisions on acceptable discharges to water resources,siting of landfills, remediation or prioritization of municipalsew erage system projects. The first two elements of the W Q S arethe S tandards, which set an overall policy for management of waterquality, and the Criteria, which are descriptive and numericalstandards that describe the allowable parameters and goals forvarious water quality classifications. A discussion of these twoelements is found in the W ater Q uality S tandards documentavailable on the CT DEEP website. The third element is theClassifications and the W ater Q uality Classification Maps whichshow the Classification assigned to each surface and groundw aterresource throughout the S tate. The W Q S are adopted using a publicparticipation process. The W Q C maps are also adopted using apublic participation process but go through hearings separatelyfrom the S tandards and Criteria hearings. R evision and adoption ofthe W Q C data occurs in accordance with the public participationprocedures contained in S ection 22a-426 of the ConnecticutGeneral S tatutes. Ground W Q C is subject to Connecticutregulation and changes must be review ed and adopted. All changesto the S urface W Q C require an adoption process which is subjectto federal review and approval in addition to CT regulation. Theadoption dates for the W Q C by major drainage basin are:Housatonic R iver, Hudson R iver and Southw est Coastal Basins -March 1999; Connecticut R iver and South Central Coastal Basins -February 1993; Thames R iver, Pawcatuck R iver and SoutheastCoastal Basins - December 1986. S urface W ater Classifications donot change after the adoption date until the next major revision.Ground W ater Classifications may change after the adoption dateunder specific circumstances. The map may have more than oneW Q C adoption date because a town may be in more than onemajor drainage basin.SUR FACE W ATER S in Connecticut are divided into freshw aterclassified as AA, A, B or B* and saline waters classified as SA orSB. Class AA designated uses are existing or proposed drink ingw ater supplies; habitat for fish and other aquatic life and wildlife;recreation; and water supply for industry and agriculture. Class Adesignated uses are habitat for fish and other aquatic life andw ildlife; potential drink ing water supplies; recreation; navigation;and water supply for industry and agriculture. Class SA designateduses are habitat for marine fish, other aquatic life and wildlife;shellfish harvesting for direct human consumption; recreation;industrial water supply; and navigation. Class B designated usesare habitat for fish and aquatic life and wildlife; recreation;navigation; and industrial and agricultural water supply. Class B*,applicable to Candlewood Lak e, is a subset of Class B and isidentical in all ways to the designated uses, criteria and standardsfor Class B waters except for the restriction on direct discharges.Class SB designated uses are habitat for marine fish and aquaticlife and wildlife; commercial shellfish harvesting; recreation;industrial water supply; and navigation.
S urface waters which are not specifically classified shall beconsidered as Class A or Class AA. S urface waters in GA groundw ater areas are assumed Class A or Class SA unless otherwiseindicated. S urface waters in GAA ground water areas are assumedClass AA unless otherwise indicated.On the W Q C map a surface water quality goal of A is representedby blue colored water bodies. S urface water quality goal of AA isrepresented by purple colored water bodies. S urface water qualitygoal of B is represented by gold colored water bodies.GR OUND W ATER S in Connecticut are classified as GAA, GA,GB and GC. Class GAA designated uses are existing or potentialpublic supply of w ater suitable for drink ing without treatment andbaseflow for hydraulically-connected surface water bodies. TheClass GAAs is a subclass of GAA for ground water that is tributaryto a public water supply reservoir. The area of contribution to apublic water supply well is represented by a 500-foot radius aroundthe well and is assumed to be Class GAA unless otherwiseclassified. Class GA designated uses are existing private andpotential public or private supplies of water suitable for drink ingw ithout treatment and baseflow for hydraulically-connectedsurface water bodies. All ground waters not specifically classifiedare considered as Class GA. Class GB designated uses areindustrial process water and cooling waters and baseflow forhydraulically-connected water bodies and is presumed not suitablefor human consumption without treatment. Class GC designateduses are assimilation of discharges authorized by theCommissioner pursuant to S ection 22a-430 of the General S tatutes.On the W Q C map GA is represented by white colored land areas.Class GAA and class GAAs are represented by blue colored landareas. The area of contribution to a public water supply well isshown by a blue cross-hatch overprint. A notation of GAAfollowed by a state abbreviation indicates a watershed thatcontributes to the public water supply for a state other thanConnecticut. Class GA or Class GAA areas that currently may notbe meeting the GA or GAA standards are represented on the W Q Cmaps by tan colored land areas. Class GB is represented by greencolored land areas. Class GC is represented by magenta coloredland areas.FINAL AQ UIFER PR OTECTION AR EAS (Level A) are includedon the W Q C maps for informational purposes. These areas areanticipated to be reclassified GAA during the next major basinupdates, subject to public participation. The Aquifer ProtectionProgram helps protect Connecticut’s public drink ing waterresources by delineating aquifer protection areas (also calledw ellhead protection areas) for public supply wells and establishingland use regulations within these areas. These areas represent theland area contributing ground water to active public water supplywells or well fields that serve more than 1000 people and are set insand and gravel aquifers (stratified drift deposits).
DATA SOUR CESW ATER Q UALITY CLAS S IFICATIONS DATA – W ater qualityclassifications shown on this map are based on information fromthe following digital spatial datasets that are typically showntogether – Ground W ater Q uality Classifications Poly, S urfaceW ater Q uality Classifications Line, and S urface W ater Q ualityClassifications Poly. The map legend above reflects the content ofthese three data sources. These W Q C data were initially compiledon 1:24,000-scale 7.5 minute USGS topographic quadrangle mapsand later digitized at 1:24,000 scale. For example, the S urfaceW ater Q uality Classifications Line and S urface W ater Q ualityClassifications Poly digital data assigns surface water qualityclassifications to water bodies such as rivers, streams, reservoirs,lak es, ponds and coves found in 1:24,000-scale hydrography dataavailable from CT DEEP. The hydrography may not include all thew aterbodies in Connecticut. The Ground W ater Q ualityClassifications Poly data assigns ground water qualityclassifications, at 1:24,000 scale, to the remaining land areas inConnecticut.AQ UIFER PR OTECTION AR EA DATA – Aquifer ProtectionAreas shown on this map are from the Aquifer Protection Areadigital dataset which contains polygon data intended to be used at1:24,000 scale. The dataset contains regulated areas classified asLevel A Aquifer Protection Area (Final) and Level B AquiferProtection Area (Preliminary). The Level B areas are not shown onthe W Q C maps. The data was collected from 1991 to the presentand is actively updated as Final area mapping replaces earlierPreliminary areas. The Aquifer Protection Areas are delineated by
the individual water companies owning the well fields andsubmitted to the CT DEEP for approval. Preliminary mappingprovides a general estimate of the area contributing ground waterto the well field. Final mapping is based on extensive, site-specific,detailed modeling of the ground water flow system. CT DEEP mayadjust Final area boundaries to be consistent with 1:24,000 scaletopography and base map data where appropriate during theapproval process.MAJOR DR AINAGE BASIN DATA – Major drainage basinsshown on this map are from Major Basin Line data developed byCT DEEP and intended to be used at 1:24,000 scale.BASE MAP DATA - Based on data originally from 1:24,000-scaleUSGS 7.5 minute topographic quadrangle maps published betw een1969 and 1992. It includes political boundaries, railroads, airports,hydrography, geographic names and geographic places. S treets andstreet names are from Tele Atlas® copyrighted data.
