Water Testing During a Home Inspection for Homes with Private Wells
When purchasing a home with a private well, water quality is a crucial part of the home inspection process. Unlike municipal water supplies, private wells are not regulated, meaning the homeowner is responsible for ensuring the water is safe to drink and use. During the home inspection period, it’s important to arrange for comprehensive water testing to protect your investment — and your health.
What to Expect During the Water Testing Process
During your home inspection, your inspector or a certified laboratory will typically collect a water sample directly from the home’s kitchen faucet or another primary point of use. This sample is then analyzed for a range of potential contaminants. Results are usually available within a few days to a week, depending on the types of tests being conducted.
If any issues are detected, you may negotiate repairs, filtration installations, or even reconsider your purchase, depending on the severity and nature of the contamination.
Common Types of Contaminants in Well Water
There are several categories of contaminants that water testing may reveal:
- Bacteria and Microorganisms:
- Coliform bacteria and E. coli are indicators of potential sewage contamination and can cause serious illness if consumed.
- Chemical Contaminants:
- Nitrates and nitrites often come from fertilizers, septic systems, and animal waste. High levels are particularly dangerous for infants and pregnant women.
- Lead and heavy metals can leach into water from plumbing systems or natural deposits.
- PFAS/PFOA Chemicals:
- Sometimes called “forever chemicals,” PFAS (Per- and Polyfluoroalkyl Substances) and PFOA (Perfluorooctanoic Acid) are man-made chemicals used in industrial applications and consumer products. These substances are highly persistent in the environment and the human body, and exposure has been linked to various health concerns, including cancer, hormone disruption, and immune system effects.
- Volatile Organic Compounds (VOCs):
- These can come from industrial pollution, fuel leaks, or agricultural activities and may affect both the taste and safety of your water.
- Radon:
- In some areas, naturally occurring radon gas can dissolve into groundwater, posing a potential risk for internal organ cancers when ingested or inhaled after it releases into the air.
Why Water Testing Matters
Safe drinking water is essential to your family’s health and your home’s long-term value. Identifying any problems early allows you to make informed decisions about treatment options or adjustments before you close on the property. In some cases, mortgage lenders or local regulations may even require water quality certification before approving financing.
