 Groundwater
- Antifreeze information page. Antifreeze poses perils for pets and wildlife.
- Aquifer mapping (off-site). Information from Maine Geological Survey.
- Contacts. Who does what.
- Drinking Water Program (off-site).
Helps public water systems comply with the federal Safe Drinking Water Act and state regulations, provides technical assistance, works with systems to protect source water areas and provides grants or loans funds for infrastructure improvements.
- EGAD.
The Maine Environmental and Groundwater Analysis Database (EGAD) is designed to store site and water quality information
- Groundwater links. Links to agencies, organizations, and more.
- Groundwater quiz (for highschool students). Can you answer these groundwater questions?
- Integrated water quality monitoring and assessment reports.
This report, also known as the 305(b) report as it is required by Section 305(b) of the Clean Water Act, summarizes water quality data collected by the DEP as well as numerous other state, federal and tribal government agencies, volunteer water monitoring organizations, and other sources.
- National primary and secondary drinking water regulations (off-site: EPA). Legally enforceable standards that apply to public drinking water sources. Primary standards protect public health by limiting the levels of contaminants in drinking water.
- Plumbing Control Program (off-site). This program's mission is to minimize health and safety hazards associated with improperly installed subsurface waste water disposal systems.
- Public Water Resources Map (off-site). The Public Water Resources Map can be used to find public water supply wells and intakes, associated buffer zones, as well as land use activities (such as gasoline spills or landfills, etc) that are potential or actual threats to groundwater. Just register and login.
- Residential Septic System Impacts on Groundwater Quality in Maine -- Characterization of Nitrate Concentrations in Domestic Wells at 18 Subdivisions. June, 1999. Doc. No. DEPLW1999-7. Executive summary. For a copy of Part I or Part II, email.
- Septic Systems: How they work and how to keep them working (scan of an older pamphlet by Casco Bay Estuary Project and Cumberland County Soil and Water Conservation District, adapted from a Maine DEP publication).
- Source Water Protection (off-site). Information on the program to assess the vulnerability of Maine public water supplies.
- Sustainable Water Use Program (water use). The reporting program includes separate reporting thresholds for withdrawals from rivers, streams and brooks; lakes; and groundwater.
- Underground Injection Control Program. The program protects underground sources of drinking water by regulating the subsurface discharge of both hazardous and non-hazardous pollutants through injection wells.
- Water protection doesn't go on vacation. Many camps, motels and other facilities rely on septic systems to treat wastewater. Your water use and activities will affect how these treatment systems work.
- Wellwater.maine.gov. Information for the public on contaminants in wellwater, from the Maine CDC.
