Aquifer Protection Area Maps

NEW!  Aquifer Protection Area Interactive Map

This new map displays Connecticut's Aquifer Protection Areas (APAs) using an interactive GIS mapping tool. The map shows the towns in the program and the Aquifer Protection Areas for which they are responsible. The map contains layers that allow the user to zoom to view the APA mapped boundary and the parcels within that boundary. The map may be viewed using the base map, the imagery map with labels, the streets map, and the topographic map. Each Aquifer Protection Area, when selected, provides a pop-up box containing information and data for that area. The map is best viewed using Google Chrome or Firefox.

Aquifer Protection Area Interactive Map

Connecticut has approximately 123 existing aquifer protection areas located in 80 towns. To view the Aquifer Protection Areas in a specific town, select the town from the map or choose from the drop-down list. You can also view a letter-sized state-wide map of the Aquifer Protection Areas (11 x 8.5 inch) or a large state-wide map of the Aquifer Protection Areas (36 x 24 inch).

GIS shapefiles of the aquifer protection areas are also available for download on the DEEP GIS data download page. Choose the data category "Natural Resources Management" and then "Aquifer Protection Areas".

An advanced map viewer with aquifer protection area maps is available on the UCONN's CT ECO web site.

Towns with aquifer protection areas Towns with Aquifer Protection Areas

Note: Towns without Aquifer Protection Areas are shown in grey. Maps are not available for these towns.

Municipalities may be interested in protecting groundwater for future source use. The Surficial Aquifer Potential Map of Connecticut has been prepared by the Connecticut Geological Survey for statewide resource protection, water management, non-point source pollution prevention, and land use planning. The map identifies areas with greater potential for ground water supply based upon the texture and thickness of surficial aquifer deposits. (See Surficial Aquifer Potential Map.)
