Well Water Quality Testing in LA County
Independent lab analysis for private wells in the unincorporated and rural corners of LA County, where public water systems don't reach.
Protect Your Health With Professional Water Testing
Clean, safe water is essential for your family's health and your property's value. Most homes in LA County are on municipal water, but properties on private wells, more common in the unincorporated foothill and canyon areas at the county's edges, aren't automatically monitored the way a public water system is. That makes ongoing testing the homeowner's own responsibility.
Well water can pick up contaminants from agricultural runoff, aging well infrastructure, or naturally occurring minerals in the surrounding soil. Testing is the only way to know what's actually in the water your household drinks and bathes in, and results can change over time even if nothing on the surface looks different.
What Well Water Testing Checks For
Our testing screens for microbiological contaminants like coliform and E. coli bacteria, heavy metals including lead, arsenic, and mercury, nitrates and nitrites (which carry particular risk for infants and pregnant women), volatile organic compounds from nearby industrial or agricultural activity, and general water quality markers like pH, hardness, and mineral content.
A certified inspector collects your sample on-site following contamination-prevention protocols, so the results reflect what's actually in your water, not something introduced during collection.
Most results are available within three to five business days after we collect your sample. You'll receive a detailed written report explaining the results and, if anything comes back elevated, clear next steps, including referrals to treatment professionals when needed. We test and report; we don't sell or install water treatment systems.
Because we're not selling a treatment system or a filtration package, there's no incentive to tell you a problem exists when it doesn't. If your water tests clean, the report says exactly that, and you can move forward with confidence instead of a sales pitch.

Well Water Quality Testing FAQ
How often should I test my well water?
Annual testing is generally recommended for bacteria and nitrates. Heavy metals can be tested less frequently, roughly every two to three years, unless something changes nearby that could affect your water source.
Is well water testing required when selling a property?
It's often requested by lenders or inspectors during a real estate transaction involving a well, and having current, independent results ready can help keep a sale on schedule.
What happens if contaminants are found?
Your report will explain what was found and at what level, along with recommended next steps. We can refer you to treatment professionals, but we don't install treatment systems ourselves, so our recommendation stays independent.
Do you also test mold and air quality?
Yes. See our Basic Mold Inspection and Total Home Health Inspection pages, or call to discuss combining services in one visit.
