Each year, bacterial contamination forces the closure of hundreds of acres of clam flats in southern Maine. These are the same bacteria that can pose a health risk at popular swimming beaches. Fecal coliform and E. coli bacteria are used as indicators that other, more harmful, pathogens may be present in coastal waters. But since wildlife, domestic animals, and humans can all be sources of fecal coliform, it is difficult for managers to identify the exact source of the bacteria.

The Maine Healthy Beaches (MHB) Program is a statewide effort to monitor water quality and protect public health on Maine’s coastal beaches. Funded by a $255,000 grant from US EPA, the MHB Program is a unique partnership involving municipalities, state parks, the University of Maine Cooperative Extension/Sea Grant, Maine Department of Environmental Protection, state and federal agencies, nonprofit organizations, and citizen volunteers. Beaches are monitored using quality assured methods and the monitoring effort established through this program helps ensure Maine's coastal beaches are safe and healthy places to recreate.
