A major sewer line failure in Haverhill, Massachusetts, has unleashed a flood of untreated wastewater into the Merrimack River, forcing beaches and shellfish areas to close just as the region heads into a holiday weekend and a punishing heat wave. State and local officials are scrambling to repair the break, which has been pouring an estimated 8 million gallons of raw sewage into the river each day.

A Public Health Emergency North of Boston

The contamination has shut down swimming at beaches in Ipswich, Newburyport, and Salisbury, a painful blow with the Fourth of July approaching and temperatures set to soar. The timing could hardly be worse for a region that depends on its shoreline during the peak of summer.

Governor Maura Healey said Monday that a whole-of-government response was underway to halt the overflow, stressing the danger to public health. She emphasized that protecting public health was the top priority and said she had directed state agencies to work closely with the City of Haverhill to resolve the problem as quickly as possible. Healey added that officials would keep moving with urgency to safely reopen the beaches and waterways during the important holiday week and expected heat wave.

How the Break Happened

The failure occurred at a pump station on South Mill Street, where the line gave way amid heavy rains on Friday night, according to Haverhill Mayor Melinda Barrett.

Since then, the city has been working around the clock on emergency repairs. Crews are now attempting to install a temporary pipeline that would link the pump station to the city’s wastewater treatment plant and stop the discharge altogether. Barrett said every effort was being made to minimize environmental damage and restore normal wastewater operations as safely and swiftly as possible.

She also urged caution from the public, advising residents and recreational users to keep avoiding contact with the Merrimack River near Haverhill and downstream until further notice, citing the potential presence of elevated bacteria and other pollutants.

Mounting Concern Over the Holiday Timing

Local leaders underscored just how high the stakes are with the holiday weekend bearing down. State Senator Bruce Tarr of Gloucester, the Republican minority leader whose district includes Ipswich, Newburyport, and Salisbury, called a swift repair critical.

Tarr described the ongoing release of millions of gallons of untreated effluent as an emergency carrying many potentially serious consequences. He warned of risks to public health, beachgoers, commercial and recreational fisheries, the regional economy, and the environment, all unfolding as one of the busiest stretches of summer activity arrives.

Shellfish Areas Shut Down

The fallout has extended beyond swimming. Gloucester officials announced that shellfish areas in several locations, including the Annisquam River and Good Harbor Beach, were closed at the direction of the state Division of Marine Fisheries.

These closures reflect the broader threat the contamination poses to the area’s fisheries, a vital part of the local economy and a resource that requires clean water to remain safe.

A Growing List of Closed Beaches

The sewer failure first prompted Newburyport to close Plum Island beach over the weekend, with Ipswich and Salisbury beaches following on Monday, according to a state water-quality dashboard.

In Ipswich, the closures swept up Crane Beach, a popular destination run by the Trustees of Reservations, along with Pavilion, Steep Hill, Clark, and Little Neck beaches. The town said these would remain closed until testing of water samples shows the water is safe for swimming once again.

Ipswich Public Health Director Colleen Fermon acknowledged the difficult timing. She noted that the closures came at an unfortunate moment with the incoming heat wave and Fourth of July holiday, but stressed that the situation represented a serious public health concern that could not be ignored.

Salisbury Beach, operated by the state Department of Conservation and Recreation, was closed at both of its access points, the town center and the state reservation, according to state data.

What Comes Next

For now, the focus remains on stopping the discharge and clearing the water for safe use. The beaches and shellfish areas will reopen only once testing confirms the water no longer poses a hazard, a process that depends heavily on how quickly crews can complete the temporary pipeline and end the flow of sewage.

As families across the region look forward to a holiday weekend by the water, the message from officials is clear: stay out of the affected areas until the all-clear is given. The combination of contaminated water, soaring heat, and a major holiday makes the situation especially urgent, and authorities are racing against both the clock and the calendar to restore one of the area’s most cherished summer resources.
