With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.

You can paint over lead paint, or “encapsulate” it with a special paint that includes an ingredient called an encapsulant. The EPA approves encapsulation as a lead paint removal method as long as the paint remains undisturbed. Standard types of paint without an “encapsulant” from the big box stores or hardware stores do not meet EPA standards for remediation of lead-based paint.

Iron sediments from rusty pipes are not likely to cause health problems. While a glass of yellow-hued water is off-putting, it is generally safe to drink yellow water in the short term. But you certainly want to address this problem. In the meantime, switching to bottled water until the yellow water issue is resolved is a good idea. 

Structural problems with the foundation or roof, water damage, and significant plumbing or electrical issues are all considered major red flags in a home inspection. Of these, a structural problem related to the foundation is often the most severe. Foundation repairs are typically the most expensive and intrusive to carry out, averaging around $5,000 but sometimes reaching up to $16,000. Because these problems can pose safety risks and be costly to fix, you should ask your inspector detailed questions about any identified issues. You will need to carefully consider how major problems affect what you’re willing to pay for the home, or if you want to proceed with the sale at all.
