Frequently Asked Questions
Common questions about well water testing and safety.
How often should I test my well water?
The EPA recommends testing well water annually for bacteria (total coliform, E. coli) and nitrates. Comprehensive testing for heavy metals, pesticides, and other contaminants should be done every 3–5 years. Test more frequently if you notice changes in taste, odor, or color, or after flooding, nearby construction, or septic system work.
How much does well water testing cost?
DIY well water test kits cost $20–$200 depending on the number of contaminants tested. Professional laboratory analysis costs $100–$500 for comprehensive panels covering bacteria, minerals, heavy metals, and chemical contaminants. State health department testing may be available at reduced cost in some areas.
What should I test my well water for?
Essential tests include bacteria (total coliform, E. coli), nitrates/nitrites, pH, hardness, and total dissolved solids. Based on your region, also test for arsenic, lead, iron, manganese, radon, fluoride, and volatile organic compounds. Your state health department can recommend area-specific contaminants to test for.
Is well water safe to drink?
Approximately 23 million US homes rely on private wells. A USGS study found that 45% of tested wells had at least one contaminant exceeding health guidelines. Unlike public water systems, private wells are not regulated by the EPA. Regular testing is the only way to ensure your well water is safe to drink.
What are signs of contaminated well water?
Warning signs include unusual odor (rotten eggs suggests hydrogen sulfide, bleach-like smell may indicate chlorine), discoloration (brown/orange from iron, blue-green from copper), changes in taste, staining on fixtures or laundry, and unexplained gastrointestinal illness. However, many dangerous contaminants like arsenic and bacteria have no visible signs.
What certifications should a water testing lab have?
Water testing labs should hold state health department certification and use EPA-approved analytical methods. Look for accreditation from organizations like The NELAC Institute (TNI) or state environmental laboratory certification programs. Certified labs follow strict quality assurance procedures and chain-of-custody protocols.
