Regulatory Agencies

Massachusetts Department of Environmental Protection (DEP)

U.S. Environmental Protection Agency (EPA) Region 1

See national section for basic information and federal regulations.

Comparison: State vs. Federal

Rules. Massachusetts follows the federal Clean Water Act as it relates to biological monitoring to determine effluent toxicity. The Massachusetts Department of Environmental Protection (DEP) may also require toxicity testing on a case-by-case basis and actual testing requirements are site-specific. See the national section BIOASSAYS/BIOMONITORING for additional guidance.

A facility's National Pollutant Discharge Elimination System (NPDES) permit will specify the type of testing required. For more information about wastewater discharge permit requirements in Massachusetts, see the state section NPDES PERMIT.

The state has also developed an environmental laboratory certification program for testing parameters for both chemistry and microbiology.

Massachusetts also follows the U.S. Environmental Protection Agency's (EPA) federal requirements for bioassay testing for the disposal of dredge and fill material.
