SOUTHWICK — A routine test of Southwick’s water supply from Springfield Water and Sewer flagged a contamination of haloacetic acids from a sample taken just before the water entered Southwick’s system.
Public Works Director Randy Brown said Thursday that a series of four tests in recent months revealed higher levels of the substance, known as HAA5. The chemical forms after a reaction between chlorine used to disinfect the water and substances that can be naturally found in water. The Springfield Water and Sewer Commission has informed several communities of the same kind of contamination in recent years, including Agawam, East Longmeadow and Springfield itself.
“Springfield Water and Sewer has been trying to address the problem for years, but now it has caught up to us,” said Brown.
