Fifty-two facilities in violation as summer low flows peak

July 21: a summer low-flow day, when a river's power to dilute what enters it shrinks to its annual minimum. The same discharge that passes largely unnoticed in April's high water becomes, in midsummer heat, a far larger and more visible share of total river volume. Right now, across the Gulf of Maine Coastal Plain, fifty-two facilities are in significant non-compliance with their Clean Water Act discharge permits — and the timing could hardly be worse. The violators include gravel operations like Plourde Sand & Gravel, food processors such as BrightFarms, industrial manufacturers, and wastewater treatment plants — including the Manchester and Nashua facilities on the Merrimack — spread across the watershed.

All fifty water bodies formally assessed within the region already carry impairment designations; not one meets its designated water quality standards. The Clean Water Act was built around exactly this seasonal dynamic — the recognition that summer low flows demand stricter compliance. But a violation record this broad, at this moment of peak vulnerability, suggests that the law's protective intent and its enforcement reality have drifted far apart.
