Cobleskill, New York's Home for

Cobleskill’s municipal water system is regulated to meet all state and federal standards. However, recent testing detected Total Trihalomethanes (TTHMs) and Haloacetic Acids (HAA5)—byproducts of chlorine disinfection—at levels approaching regulatory limits:

While these results meet federal standards, long-term exposure to these byproducts has been linked to increased cancer risk. In addition, recent monitoring showed elevated sodium levels (22 mg/L on 9/25/2024) and trace detections of lead (0.005 mg/L) and copper (0.0488–0.419 mg/L), though both were below the EPA’s action levels.

Because lead and copper can fluctuate due to pipe corrosion, it is important for homes with older plumbing to consider regular testing. For extra peace of mind, Culligan offers free home water testing.

The Cobleskill water quality report does not list a specific hardness level. The water source is surface water drawn from three ponds (Dow, Holding, and Smith), which typically have lower hardness than groundwater sources. However, seasonal changes and distribution system variables can alter hardness levels. Residents noticing soap scum, mineral spots, or dry skin may benefit from a hardness test.

The 2024 Cobleskill water quality report does not list PFAS testing results. PFAS (per- and polyfluoroalkyl substances) have been detected in many New York water systems, and the EPA has recently set maximum contaminant levels for PFOA and PFOS at 4 parts per trillion (ppt). Even at low levels, PFAS are persistent and linked to long-term health concerns. For residents concerned about PFAS, specialized whole-house filtration systems are available.

Yes. The Cobleskill water system adds fluoride to their tap water. In 2024, daily monitoring showed fluoride levels generally within the recommended range of 0.1–1.0 mg/L, close to the CDC target.

Cobleskill’s water supply comes from surface water sources, specifically three ponds: Dow, Holding, and Smith, located at 174 Dow Street in Cobleskill. The water is treated with aluminum sulfate for clarification, filtered, disinfected with chlorine, and fluoridated before distribution to homes and businesses.

Because Cobleskill’s water source is primarily surface water, hardness is likely on the lower end, but seasonal changes can introduce mineral content. A water softener can help if you experience:

Culligan offers free testing to determine your specific water hardness.

Yes. While Cobleskill’s water meets federal regulations, it still contains disinfection byproducts (TTHMs and HAA5), sodium, and trace metals like lead and copper. Installing an under-sink reverse osmosis system or whole-home filtration can reduce these contaminants for safer, better-tasting water.
