Private Well Water Testing in Jamestown & Western NY
Chautauqua County’s varied bedrock geology means well water chemistry changes significantly from one township to the next. Properties drilled into the shale formations south of Jamestown commonly show iron and sulfur; wells tapping the limestone-rich aquifers around Mayville and Westfield tend toward hardness and occasionally arsenic; shallow agricultural-area wells in the Cattaraugus Creek drainage frequently test positive for nitrates and seasonal coliform. New York State requires a bacteria test before closing on any property with a private well, but that single test doesn’t screen for any of the above. McCandless conducts comprehensive water quality panels — sampling for iron, manganese, hardness, pH, nitrates, arsenic, sulfur, and bacteria — so treatment recommendations are based on what’s actually in your water, not assumptions.

Frequently Asked Questions
Why is water testing important for well owners?
Regular water testing ensures your well water is safe, clean, and free from harmful contaminants. It helps detect issues early, protecting your health and your water system.
How much does well water testing cost in Jamestown, NY?
McCandless provides free water testing with any service call. Standalone comprehensive water quality panels in the Chautauqua County area typically range $100–$250 through certified labs, depending on the number of parameters tested. For real estate transactions requiring a certified test, we can coordinate with state-certified labs serving Western NY.
What contaminants does McCandless Well Drilling and Services, Inc. test for?
We test for pH, Iron, Hardness, Total Dissolved Solids, Manganese, sulfur and other common contaminants that can affect water quality and safety.
What does a standard well water test check for in New York State?
New York State recommends testing private wells annually for coliform bacteria and nitrates at minimum. A comprehensive panel also covers iron, manganese, hardness, pH, sulfates, arsenic, and turbidity. For older homes with galvanized or lead-solder plumbing, lead testing is strongly recommended. Chautauqua County properties near agricultural land should add pesticides and herbicides to the panel.
How often should I test my well water in Western NY?
Annual testing is the standard recommendation for Chautauqua County well owners. Test immediately after: any flooding event near the well, a change in water taste or odor, system work on your well or pressure tank, or the birth of a child or pregnancy (nitrate sensitivity). Spring — after snowmelt — is the highest-risk period for coliform intrusion and the optimal time for annual testing.
Can I perform water testing myself, or do I need a professional?
While home test kits are available, professional testing provides more accurate and comprehensive results, ensuring reliable water quality analysis.
What do I do if my well water test shows bacteria?
A positive coliform result requires disinfection of the well — typically a shock chlorination treatment — followed by a retest 10–14 days later to confirm clearance. McCandless performs well shock chlorination throughout Chautauqua and surrounding counties. If multiple retests continue to show positive results, a UV system or in-line chlorination unit is the long-term solution.
Can I test my well water myself with a home kit?
Home water test strips provide a rough screen for certain parameters (hardness, pH, chlorine, nitrate) but are not accurate enough for treatment decisions and are not accepted for real estate transactions or regulatory compliance. For actionable results, use a state-certified laboratory or a professional water test. McCandless’s on-site testing provides same-visit preliminary results with certified lab confirmation.
