Protestors demonstrated outside of the Agawam, Massachusetts, offices of gas pipeline company Kinder Morgan Wednesday. They are upset that more than 16,000 gallons of contaminated water were released improperly last fall.
The water contained a number of potentially dangerous chemicals. It was used to test a recently-built pipeline running from Agawam into northern Connecticut.
According to federal filings, Kinder Morgan said the water did not impact any wetlands, and blames a contractor for the incident.
Protestor Priscilla Lynch said the company should have done more to prevent the spillage.
"Do you just say, 'Because I contract with people, I have no responsibility?'" Lynch said. "They have responsibility for this. They should know what's going on with their contractors, and they should know what's going on on their own property."
Massachusetts U.S. Senators Ed Markey and Elizabeth Warren have pressed federal regulators for more information about the incident.
A Kinder Morgan spokeswoman had no further update.
