Holyoke Water Works: Inconsistent fall temperatures causing water quality issues

Hampden County

HOLYOKE, Mass. (WWLP) – Inconsistent fall temperatures are causing water quality issues for Holyoke residents Tuesday night and could have a direct impact on water supplies, according to officials. 

Holyoke Water Works said customers may notice a slight discoloration in the water quality until weather patterns begin to stabilize.  

This condition is only temporary and is a naturally occurring event called “reservoir turnover”, which Holyoke Water Works experiences almost every year. “Since Holyoke Water Works is one of the two remaining unfiltered water sources in Massachusetts, it currently does not have the treatment processes in place to address this naturally occurring event.

Customers should not be concerned about the discoloration as the drinking water “is still bacteriologically safe to drink, and use for everyday purposes, including not limited to, bathing and cooking.” 

“The warm surface water on top of the reservoir or lakes starts to cool off with the cooling fall temperatures and switches spots with the water at the bottom of the reservoir which is generally cooler. That brings some of the materials and the tannins that are naturally found in the water up to the surface in the middle parts of the water system where we actually draw the water into the supply,” said Reservoir Superintendent Matthew Smith from the Holyoke Water Works.

Anyone with questions or concerns is asked to contact the city’s Treatment Facility at (413) 532-6778
