Sec. 22a-354c. Mapping of well fields by water companies. (a) On or before July
1, 1990, each public or private water company serving one thousand or more persons
shall map at level B all areas of contribution and recharge areas for its existing wells
located in stratified drift aquifers. Not later than three years after the adoption by the
Commissioner of Environmental Protection of a model municipal aquifer protection
ordinance under section 22a-354l, each public and private water company serving ten
thousand or more persons shall map at level A all areas of contribution and recharge
areas for its existing wells located in stratified drift aquifers. Any public or private water
company that creates a new well field serving one thousand or more persons that has
not been mapped previously as an existing well shall map areas of contribution and
recharge areas for the new well field. Any map of such a new well field shall be submitted
not later than one year after the issuance of a diversion permit in accordance with section
22a-368 at level B, and not later than three years after the issuance of a diversion permit
in accordance with section 22a-368 at level A. The Commissioner of Environmental
Protection may map at level A and at level B all areas of contribution and recharge areas
for existing wells located in stratified drift aquifers that are used by any public or private
water company serving less than one thousand persons.
(b) Each public or private water company serving ten thousand or more persons
shall map all areas of contribution and recharge areas for potential wells that are located
within stratified drift aquifers identified as future sources of water supply to meet their
needs in accordance with the plan submitted pursuant to section 25-33h at level B not
more than two years after the Commissioner of Environmental Protection requests such
mapping. The Commissioner of Environmental Protection shall identify and make recommendations for mapping, or shall map, all remaining significant areas of contribution
and recharge areas for potential wells located in stratified drift aquifers not identified
by a public or private water company as a potential source of water supply within the
region of an approved plan. Mapping of any other area of contribution and recharge
areas for potential wells located in stratified drift aquifers by the commissioner shall be
completed at a time determined by the commissioner.

History: P.A. 89-305 specified that mapping is required of areas of contribution and recharge areas for wells located
in stratified drift aquifers and made technical changes; P.A. 90-275 deleted the requirement that the areas to be mapped
at level B by water companies be within their water supply service area, authorized the commissioner to map at level A
and at level B areas of contribution and recharge areas for wells located in stratified drift aquifers which are used by water
companies serving less than 1,000 persons and required the commissioner to either map or make recommendations for
mapping all remaining significant areas of contribution and recharge areas for potential wells located in stratified drift
aquifers not identified by water companies as a potential source of water supply; P.A. 91-386 amended Subsec. (a) to
extend the time for mapping at level A from July 1, 1992, to July 1, 1994; May Sp. Sess. P.A. 92-11 amended Subsec. (a)
to change date from July 1, 1994, to January 1, 1996, for aquifer mapping; P.A. 93-337 amended Subsec. (a) to change
deadline for mapping from January 1, 1996, to three years after adoption by commissioner of model ordinance under Sec.
22a-354l; P.A. 07-85 amended Subsec. (a) to require water companies to map any new well field created and submit such
map to department after issuance of a diversion permit, and amended Subsec. (b) to remove Subdiv. designators, to delete
provision re mapping at level A and to change timeframe to not more than two years after request for mapping by commissioner, rather than two years after approval of plan.
