EX PLANATIONW ATER Q UALITY CLAS S IFICATIONS (W Q C) MAPS are oneof the elem ents 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 cleanwater 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 m any areas, forexample decisions on acceptable discharges to water resources,siting of landfills, rem ediation or prioritization of m unicipalsewerage system projects. The first two elem ents of the W Q S arethe S tandards, which set an overall policy for m anagem ent of waterquality, and the Criteria, which are descriptive and num ericalstandards that describe the allowable param eters and goals forvarious water quality classifications. A discussion of these twoelem ents is found in the W ater Q uality S tandards docum entavailable on the CT DEEP website. The third elem ent is theClassifications and the W ater Q uality Classification Maps whichshow the Classification assigned to each surface and groundwaterresource throughout the S tate. The W Q S are adopted using a publicparticipation process. The W Q C m aps 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 m ust be reviewed 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 m ajor drainage basin are:Housatonic R iver, Hudson R iver and Southwest Coastal Basins -March 1999; Connecticut R iver and South Central Coastal Basins -February 1993; Tham es R iver, Pawcatuck R iver and SoutheastCoastal Basins - Decem ber 1986. S urface W ater Classifications donot change after the adoption date until the next m ajor revision.Ground W ater Classifications m ay change after the adoption dateunder specific circum stances. The m ap m ay have more than oneW Q C adoption date because a town m ay be in more than onem ajor drainage basin.SUR FACE W ATER S in Connecticut are divided into freshwaterclassified as AA, A, B or B* and saline waters classified as SA orSB. Class AA designated uses are existing or proposed drink ingwater 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 andwildlife; potential drink ing water supplies; recreation; navigation;and water supply for industry and agriculture. Class SA designateduses are habitat for m arine fish, other aquatic life and wildlife;shellfish harvesting for direct hum an 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 m arine fish and aquaticlife and wildlife; com m ercial 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 groundwater areas are assum ed Class A or Class SA unless otherwiseindicated. S urface waters in GAA ground water areas are assum edClass AA unless otherwise indicated.On the W Q C m ap 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 water suitable for drink ing without treatm ent andbaseflow for hy draulically-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 assum ed to be Class GAA unless otherwiseclassified. Class GA designated uses are existing private andpotential public or private supplies of water suitable for drink ingwithout treatm ent and baseflow for hy draulically-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 forhy draulically-connected water bodies and is presum ed not suitablefor hum an consumption without treatm ent. Class GC designateduses are assim ilation of discharges authorized by theCom m issioner pursuant to S ection 22a-430 of the General S tatutes.On the W Q C m ap 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 m ay notbe m eeting the GA or GAA standards are represented on the W Q Cm aps by tan colored land areas. Class GB is represented by greencolored land areas. Class GC is represented by m agenta coloredland areas.FINAL AQ UIFER PR OTECTION AR EAS (Level A) are includedon the W Q C m aps for inform ational purposes. These areas areanticipated to be reclassified GAA during the next m ajor basinupdates, subject to public participation. The Aquifer ProtectionProgram helps protect Connecticut’s public drink ing waterresources by delineating aquifer protection areas (also calledwellhead 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 m ap are based on inform ation 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 m ap legend above reflects the content ofthese three data sources. These W Q C data were initially compiledon 1:24,000-scale 7.5 m inute USGS topographic quadrangle m apsand 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, stream s, reservoirs,lak es, ponds and coves found in 1:24,000-scale hy drography dataavailable from CT DEEP. The hy drography m ay not include all thewaterbodies in Connecticut. The Ground W ater Q ualityClassifications Poly data assigns ground water qualityclassifications, at 1:24,000 scale, to the rem aining land areas inConnecticut.AQ UIFER PR OTECTION AR EA DATA – Aquifer ProtectionAreas shown on this m ap 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 (Prelim inary). The Level B areas are not shown onthe W Q C m aps. The data was collected from 1991 to the presentand is actively updated as Final area m apping replaces earlierPrelim inary areas. The Aquifer Protection Areas are delineated by
the individual water companies owning the well fields andsubm itted to the CT DEEP for approval. Prelim inary m appingprovides a general estim ate of the area contributing ground waterto the well field. Final m apping is based on extensive, site-specific,detailed modeling of the ground water flow system. CT DEEP m ayadjust Final area boundaries to be consistent with 1:24,000 scaletopography and base m ap data where appropriate during theapproval process.MAJOR DR AINAGE BASIN DATA – Major drainage basinsshown on this m ap 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 m inute topographic quadrangle m aps published between1969 and 1992. It includes political boundaries, railroads, airports,hy drography, geographic nam es and geographic places. S treets andstreet nam es are from Tele Atlas® copyrighted data. Base m apinform ation is neither current nor complete.R ELATED INFOR MATIONThis m ap is intended to be printed at its original dim ensions inorder to m aintain the 1:24,000 scale (1 inch = 2000 feet).W ATER Q UALITY S TANDAR DS - Go to the CT DEEP websitefor a sum m ary and the full text of the “W ater Q uality S tandards”and for other inform ation on water quality.AQ UIFER PR OTECTION AR EAS - Go to the CT DEEP websitefor more inform ation.
