Troy adds orthophosphate to drinking water

TROY (NEWS10) - On Wednesday, the City of Troy began adding orthophosphate to its water treatment process, a move mandated by the Environmental Protection Agency (EPA) to address elevated lead levels.

Troy Mayor Carmella Montello explained that the decision to introduce orthophosphate dates back to 2021, when lead levels in the city's water supply exceeded the EPA's safety threshold. "This is EPA mandated, much like the lead pipe removal," Mayor Montello stated. "We were notified approximately a year and a half ago. Through the process, we had the dose certified, engineered the plan, and finally got it approved."

Orthophosphate, a common water treatment chemical, is known for its effectiveness in reducing lead levels in drinking water. Andrew Golden, Maintenance Manager of Public Utilities for Troy, emphasized the anticipated impact. "We should start to see a decrease in our lead levels within two to four months," he said.

Russ Reeves, the Head Engineer at the Department of Public Utilities in Troy, illustrated the minimal amount of orthophosphate being introduced. "If you envision a million red M&M's and introduce one green one, that's one part per million. So it's a very, very small amount."

Local pediatrician Dr. James Saperstone acknowledged public concerns about the new chemical but reassured residents of its safety. "People might be worried when they hear the word orthophosphate because it sounds like a dangerous chemical, but in fact, it's safe and used in many water systems to prevent corrosion."

The City of Troy supplies water to several surrounding areas, including Halfmoon, Menands, parts of East Greenbush, North Greenbush, Brunswick, Schaghticoke, Poestenkill, the Village of Waterford, and Rensselaer. Rensselaer Mayor Mike Stammel welcomed the news, saying, "This is definitely a positive step for the health and safety of those who drink potable water."
