Roughly three in four private drinking-water wells across Western New York and Northwestern Pennsylvania went untested in the past year, and homeowners who skip regular testing pay an average of $6,400 in preventable damage to plumbing, appliances, and well equipment, according to a new water quality analysis by McCandless Well Drilling and Services.

The study also found that the average private well in the region had gone 4.2 years between water tests — more than four times the annual interval recommended by the EPA for private systems — with the longest gaps concentrated in older rural properties where families assume clear-looking water is safe until a pump fails, an appliance corrodes, or a household member gets sick.
Mini Methods
The McCandless Well Drilling and Services analysis reviewed more than 300 private well water tests, treatment installations, and service records across rural Chautauqua and Cattaraugus counties in New York and Erie and Warren counties in Pennsylvania — communities including Jamestown, Frewsburg, Bemus Point, Mayville, Westfield, and surrounding areas that depend on private wells rather than municipal water. The study examined testing frequency, the contaminants most often detected, the relationship between water quality and the lifespan of pumps and appliances, seasonal shifts in bacterial detections, and the effect of documented water quality on both repair costs and property value. Wells were grouped by testing history — regularly tested, occasionally tested, and never tested — and tracked for contaminant levels and total lifetime cost.
Top Results
• Widespread Testing Neglect: 73% of surveyed private wells went untested in the past year, with the average well going 4.2 years between water tests — more than four times the annual testing the EPA recommends for private systems.
• What Is Actually in the Water: 58% of tested wells exceeded a safe limit for at least one contaminant, with coliform bacteria the most common problem, followed by elevated iron and manganese, hardness, and nitrates — most of it invisible, odorless, and undetectable without a lab test.
• The Cost of Skipping Treatment: Homeowners who neglected testing and treatment paid an average of $6,400 in preventable repairs and premature replacements over the life of their system, compared to roughly $2,500 for homeowners who tested annually and treated as needed — a 61% difference.
• Hard Water Cuts Equipment Life: Untreated hard and sediment-heavy water shortened the lifespan of well pumps, water heaters, and household appliances by an average of 7 years, forcing early, costly replacements that a $1,200–$3,000 treatment system would have prevented.
• Spring Thaw Raises the Risk: Bacterial detections in the region rose 42% during spring snowmelt and heavy-rain periods, when surface runoff can seep into shallow or aging well casings — making late winter and early spring the highest-risk window for untested rural wells.
• Testing Gap at Point of Sale: Only 31% of rural home sales in the study included a documented well water test, leaving buyers exposed to failing pumps, contaminated water, and treatment costs that often surface within the first two years of ownership.
• Clean Water Boosts Home Value: Homes with documented, up-to-date well water testing and treatment records sold for an average of 3.6% more than comparable rural properties with unknown or lapsed water history, adding roughly $7,900 to the median sale price.
