GENESEO – Cooperative efforts by the local highway superintendent, Town, and Village have cut the already very small levels of a potentially harmful chemical in local water by an astonishing nearly 50% since 2014.
Due to retrofit work on the local three-million-gallon water storage tank on Reservoir Road, recorded levels of Trihalomethanes (TTHM’s), a known carcinogen, have fallen from 67 micrograms per liter, the lowest recorded level in the 2014 Drinking Water Quality Report, to an all-time low of 34 micrograms per liter for August 2015.
“Historically, August has the highest TTHM levels, and this August is the lowest TTHM levels there’s ever been,” said Geneseo Highway Superintendent Larry Levey. “We used to draw water from the line before it got to the tank, and the Village put in the work to change that so we draw from after it passes through the tank.”
According to Drinking Water Quality Reports, TTHM’s are a by-product of drinking water chlorination needed to kill harmful organisms. TTHM’s are formed when source water contains large amounts of organic matter. Levey said that the source water in this case is Conesus Lake.
Town Supervisor William Wadsworth thanked Levey for his persistence in running down an effective way to mitigate the problem and convincing the right people to take action.
“Larry has the unfortunate position of sometimes having to make people see things they don’t want to see,” said Wadsworth. “He took some knuckle sandwiches and elbows to the ribs, but we thank him for being persistent. […] Ultimately, the retrofit eliminated a point of stagnation in the system that was lending to the problem.”
Levey thanked the Town and Village for their assistance with tackling the issue.
“Historically, we have been close to the maximum allowable [TTHM] levels, and even though that’s still a very, very small amount, there was a way to make it better,” said Levey, citing past Drinking Water Quality Reports. “The Village put in the work and we all thank them.”
