Source Water Assessment and Wellhead Protection

assessment1ALWI possesses extensive regional experience in Source Water Assessment Plans (SWAPs) executed in conformance with state and EPA requirements. SWAPs have been a core professional service ALWI has provided since our inception.

ALWI’s staff has completed SWAPs for approximately 130 public groundwater supply wells throughout the Mid-Atlantic region since the 1996 passage of the federal Safe Drinking Water Act amendments. This work entailed delineating wellhead protection and source water contribution areas, assembling contaminant threats inventories, preparing contingency and emergency response plans, designing and implementing shareholder participation and community outreach programs, and recommending and testifying on protective ordinances and restrictive covenants.

Exemplifying our unparalleled expertise in SWAP work, in 2000 we completed an eight-system wellhead protection and SWAP for the Cecil County (MD) Office of Planning and Zoning. That project was the recipient of the first-ever SWAP of the Year award from EPA Region III

ALWI has completed a draft Source Water Assessment and Wellhead Protection Plan, under contract to the City of Westminster and funded by a Maryland Department of the Environment (MDE) grant. Please read our news story about this important project, or the report itself may be reviewed at
