Groundwater Source Permitting — Connecticut & Massachusetts

The Safe Drinking Water Act Amendments of 1996 mandated that all states establish well head protection implementation plans. In response, the Connecticut DEEP requires all public water supplies serving more than 1,000 residents to prepare Level A maps of recharge areas for supply wells located within stratified drift aquifers. In Massachusetts, Zone II Well Head Protection Areas are required for all public water supply wells with capacities of 100,000 gallons or more per day.

LEI's water supply engineers, groundwater modelers, geologists, hydrogeologists and ecologists assist public and private water utilities to navigate the complex requirements of groundwater source permitting.

Connecticut Level A Aquifer Mapping Requirements:

•  Prepare Plan for Data Collection

•  Oversee well drilling

•  Install & calibrate stream gauges

•  Conduct aquifer parameter & induced infiltration pumping tests

•  Generate final Level A mapping & report

•  Create & calibrate groundwater models

•  Create aquifer protection zone mapping

Massachusetts Source Permitting Requirements:

•  Initial hydrogeologic assessments

•  Groundwater exploration oversight

•  Pump test proposals

•  Pump test reports

•  Zone I / Zone II delineations

•  DEP Water Management Act permitting

•  Streamflow & ecological studies
