- Water samples are accepted Monday through Wednesday at the county Hall for testing and analysis.
- New York State and EPA approve the laboratory for both drinking water and bathing beach water testing.
What Do You Need Before Testing Your Well?
Preparation determines whether a well water test Chautauqua County NY homeowner runs actually reflects the property’s true water chemistry. Bedrock geology shifts from township to township across the county. Results from a neighbor’s well rarely predict what comes out of another household’s tap.
Why Does Location Matter So Much Before Testing?
Geology dictates contamination risk. Shale formations south of Jamestown typically push iron and sulfur into groundwater, contaminants often addressed with professional water filtration. Limestone aquifers near Mayville and Westfield trend toward hardness and occasional arsenic. Properties in the Cattaraugus Creek drainage area, often surrounded by farmland, show a higher chance of nitrates and seasonal coliform bacteria.
Before scheduling a sample, property owners should complete these steps:
- Identify the property’s general geological zone (shale, limestone, or agricultural drainage).
- Confirm whether a real estate closing is pending, since New York State mandates a bacteria test for any private well changing hands.
- Locate the certified county laboratory location, the Hall R. Clothier Building in Mayville, which accepts samples Monday through Wednesday only.
- Arrange ice transport, since warm samples get refused on arrival.
Does a Bacteria Test Cover Everything?
No. The mandatory closing test screens only for total coliform and E. coli, leaving iron, arsenic, hardness — addressed through professional water softeners — and nitrates undetected. A single clean bacteria result offers no guarantee against these other risks.
What Are the Steps to Test Your Well Water?
Five steps separate a Chautauqua County property owner from a clear picture of what flows from the tap. Skip any one of them, and contamination like nitrates or bacteria can go undetected for months, putting household health at risk. A thorough well water test in Chautauqua County, NY follows a defined sequence, not a single quick check.
- Confirm who collects the sample. Private water samples gathered by anyone other than Environmental Health staff are rejected by the county program, so property owners must schedule an authorized collection rather than submitting a self-drawn sample.
- Secure a sterile bottle. These bottles come from the county laboratory Monday through Wednesday only, and a processing fee is due before an empty bottle is handed over.
- Request a comprehensive panel, not just a bacteria check. A full comprehensive water quality panel screens for iron, manganese, hardness, pH, nitrates, arsenic, sulfur, and bacteria, giving a treatment recommendation — often reverse osmosis — grounded in actual chemistry instead of guesswork.
- Submit the sample promptly to avoid degraded results from delayed processing.
- Review results with a water treatment professional before choosing filtration, disinfection, or a new well.
How Often Should Wells Near Farmland Be Retested?
Farming communities such as Randolph face elevated risk for nitrate and coliform contamination from nearby fields. Annual testing matters most for wells sitting close to active agricultural land, where runoff and fertilizer use change year to year.
Can Homeowners Collect Their Own Sample?
Self-collected samples are not accepted under the county’s private well program. Coordinating collection through Environmental Health staff, and following the Monday-through-Wednesday bottle schedule, keeps the process valid and the results reliable.

What Should You Do With Your Test Results?
Results dictate the next move, not guesswork. A property owner whose sample exceeds safe drinking water standards needs a different response than one dealing with hardness or staining. Anyone who completes a well water test Chautauqua County NY should treat the report as a decision point, then act in order:
- Compare results to state safe drinking water standards. Flagged bacteria levels call for prompt attention.
- Address bacteriological exceedances first. Disinfection instructions are available, along with guidance on whether drilling a new well, adding treatment components, or upgrading an existing system makes more sense.
- Investigate non-bacteriological concerns separately. Guidance for additional sample analysis through a certified laboratory helps pinpoint the cause.
- Weigh results against a full panel. Comprehensive testing for iron, manganese, hardness, pH, nitrates, arsenic, and sulfur keeps treatment decisions grounded in actual water chemistry, not assumptions.
