Owning a Private Well: What You Need to Know
Private wells deliver clean, affordable water to millions of U.S. homes—but unlike city water, there's no utility watching it for you. As a well owner, you are responsible for testing, maintenance, and protecting the wellhead from contamination.
Start with the essentials: locate your well record, perform annual testing, keep a secure sanitary well cap, and know when to disinfect.
Quick Start for New Well Owners
Four high-impact actions that protect your health and your system.
Get Your Well Record
Know depth, construction, pump details, and yield. It's essential for service and home sales.
Test Annually
At minimum: bacteria and nitrates every year; metals and other contaminants every 3–5 years.
Protect the Wellhead
Use a sanitary cap, keep vegetation clear, and slope ground away to prevent runoff entering.
Know When to Disinfect
After repairs, flooding, or a positive bacteria test, follow proper shock chlorination steps.
