Tap Water & Well Water Testing Recommendations

Testing your drinking water in York confirms whether contaminants like lead, nitrates, bacteria, and PFAS are entering your home. While municipal utilities test water before distribution, private plumbing and private well systems require homeowner testing.

Tap Water Testing Checklist

1.Identify your plumbing age: Homes built before 1986 in York may have lead solder or lead service lines.
2.Request your utility's latest Consumer Confidence Report (CCR) for annual municipal baseline data.
3.Use an EPA-certified laboratory or state-certified test kit for precision lead and PFAS detection (standard DIY strips cannot reliably measure trace heavy metals).
4.Collect a "first draw" sample: Test water that has sat motionless in pipes for at least 6 hours to check for plumbing corrosion.

Private Well Water Testing Checklist

•Private wells in SC are not monitored by the EPA or South Carolina Department of Health and Environmental Control — testing is 100% the homeowner's responsibility.
•Annual Test: Screen for Total Coliform Bacteria, E. coli, Nitrates/Nitrites, and pH every spring.
•Comprehensive Test (Every 3-5 Years): Test for heavy metals (Lead, Arsenic, Uranium), Volatile Organic Compounds (VOCs), and Hardness.
•Post-Disruption Testing: Immediately test well water following heavy floods, local construction, agricultural runoff, or sudden taste/odor changes.
