Cross-connections are connections between two otherwise separate pipe systems. Water supplies with cross-connections between them put your drinking water at risk. Observe water quality in existing wells by testing them annually. Test for contaminants that are most likely on your property. Further advice on testing can be obtained from your local health department or local Extension office.
Water testing is done by both public and private laboratories.
Consult your local health department. Record test results and note changes in water quality over time. Your well should require mechanical attention every 10 to 20 years. Contact a qualified well driller or pump installer. New Wells Make the well accessible for pump repair, cleaning, testing, and inspection.
