St. Johnsville, New York's Home for
Water Softeners, Water Filters,
and Water Delivery

The information above covers St. Johnsville’s public water system. If your home draws from a private well instead, none of those numbers describe your water. Wells here bring their own concerns, including iron staining, sulfur odor, hardness, manganese and bacteria, and a municipal water quality report will not tell you about any of them. Our well water treatment in St. Johnsville, NY page covers what is actually in local well water and how it gets treated.

St. Johnsville’s public water system treats and disinfects its water before distribution, and the local water quality information reported no violations. Testing still detected or monitored substances including lead, copper, chlorine, nitrate, disinfection byproducts, barium, nickel, PFAS, and 1,4-dioxane. Homeowners who want more information about the water coming from their own tap can consider local water testing and additional filtration.

St. Johnsville uses two drinking water sources. One is a drilled groundwater well in the Roland V. Swartz well field. The other is Congdon Springs, a surface water source. Water from the well is disinfected before distribution, while water from Congdon Springs is treated through slow-sand filtration and then disinfected.

Yes. The village relies on both a groundwater well and Congdon Springs. Because the two sources have different characteristics and potential contamination concerns, water quality can be influenced by both groundwater conditions and surface water conditions.

Yes. Chlorine residual was reported at 0.57 mg/L, with results ranging from 0.20 to 2.20 mg/L. Chlorine is used to disinfect the water and control microorganisms, but some homeowners may notice chlorine-related taste or odor. Whole-house carbon filtration can help reduce chlorine throughout the home.

Yes. Total Trihalomethanes were reported at 1.47 µg/L, while Total Haloacetic Acids were reported at less than 1.0 µg/L. These compounds can form when disinfectants react with naturally occurring organic material in the water.

Yes. Lead was reported at a 90th percentile level of 2.5 µg/L, with results ranging from non-detect to 3.5 µg/L. Copper was reported at a 90th percentile level of 0.413 mg/L, with results ranging from 0.0112 to 0.663 mg/L. Lead and copper can enter drinking water through service lines, plumbing, solder, and fixtures, so results can vary from one property to another.

Testing detected or monitored substances including lead, copper, nitrate, barium, nickel, chlorine residual, TTHMs, HAA5, PFOA, PFOS, 1,4-dioxane, and turbidity. These results represent the public water system as a whole, while a local water test can provide more information about conditions at an individual home.

Testing included both PFOA and PFOS. Each was reported at less than 1.67 ng/L. PFAS are a group of persistent chemicals that can be found in drinking water sources, and reverse osmosis is one treatment option homeowners may consider for reducing certain PFAS compounds at the tap.

The village tested for 1,4-dioxane and reported a result of less than 0.100 µg/L. 1,4-dioxane is an emerging contaminant that can enter water through industrial and commercial sources. Reverse osmosis may be considered as part of a treatment approach for certain dissolved contaminants.

Yes. Nitrate was detected in both water sources. The Swartz well reported 1.30 mg/L, while Congdon Springs reported 0.033 mg/L. Nitrate can enter water from fertilizers, septic systems, runoff, and natural deposits.

The local source water assessment identified the groundwater well as having very high susceptibility to bacteria, viruses, and nitrates, along with high susceptibility to several other contaminant groups. The village disinfects the water before distribution, but homeowners concerned about their individual tap water may still choose additional testing or treatment.

A specific hardness measurement was not listed in the water quality information provided. Homes may still experience mineral-related issues such as spotting on fixtures, scale buildup, dry-feeling skin, or soap that does not lather well. A local water test can determine whether a water softener would be beneficial.

A water filter may be helpful for homeowners who want to reduce chlorine taste and odor, lead, PFAS, or other contaminants at the tap. Reverse osmosis is commonly used for drinking and cooking water, while whole-house filtration can address certain water quality concerns throughout the home.

St. Johnsville residents can obtain local drinking water quality information from the Village of St. Johnsville. Homeowners who want to understand the water coming directly from their own faucets can also schedule a local water test with Culligan.
