Expert Contaminant Detection in Los Angeles County, CA

Contaminant detection is the first step to understanding what is actually in your water. Across Los Angeles County, water reaches homes from multiple sources, including imported supplies from the Colorado River, local groundwater, and the Los Angeles Aqueduct. Each source carries its own mix of potential concerns, from arsenic and nitrates to disinfection byproducts and PFAS compounds. Older pipes in some neighborhoods can add lead or bacteria to water that tested clean at the treatment plant. In agricultural zones across Ventura, Kern, and Santa Barbara counties, nitrate runoff from farming operations adds another layer of risk. Orange County and the Inland Empire draw from blended surface and groundwater supplies that can shift in composition seasonally. At Pure Water Filtration, we work with the wide range of water types and challenges California presents. Contaminant detection testing gives you a clear picture of what your water contains, so any next steps are based on real data, not guesswork. Contact us to schedule testing for your property.

Contaminant Detection FAQ

Common questions about contaminant detection in Los Angeles County, CA.

We test for a range of contaminants relevant to Southern California water, including arsenic, nitrates, PFAS compounds, disinfection byproducts, and heavy metals like lead. The specific panel can be tailored to your water source and any concerns you have noticed.

Yes. A utility report reflects conditions at the treatment plant, not at your tap in Los Angeles County. Testing at your property accounts for what happens inside your pipes and fixtures after water leaves the treatment facility.

Yes, because many contaminants like lead, PFAS, and arsenic have no taste, smell, or visible sign. Detection testing is the only way to confirm what is actually present in your Ventura County water.

Yes. We serve properties on private wells across Kern County and the Inland Empire, where groundwater can carry agricultural runoff, naturally occurring minerals, and other contaminants not covered by public utility testing.

No special preparation is needed on your end before we arrive at your Orange County property. We collect water samples directly from your taps and any other points of concern during the visit.

The results show exactly what is present in your water, which makes it straightforward to match a treatment approach to your specific situation. We work through the findings with you so you understand what the data means for your Santa Barbara County or Los Angeles County home.

Affordable, Efficient, No Leaks!! They gave an estimate that was much less than another company. I had them install a water heater and a water softening system I purchased at Home Depot. Everything was installed in half a day and they upgraded existing parts and fittings when necessary. The workmanship is great and I am extremely satisfied!!!

Kendall Moore Google review · October 2025

I had a water softener and RO drinking water installed in March of 2024. Brandon was communicative, fair, and did a great job. I meant to write a review back then, but it slipped my mind. I can’t speak to their customer service after install, because I haven’t had any issues, and my RO filters haven’t slowed down/needed changing yet. I’ll update my review when that time comes! I wish I’d made these purchases 10 years earlier instead of renting a water softener. The company I rented from before (Matilija) kept raising the monthly fee for their depreciating equipment, never came to test the equipment/water to make sure it was working, and were completely unresponsive when I called and emailed. Working with Brandon was a breath of fresh air!

We have been putting off a drinking water system on our new home for the last year. We wish we would've had done this a lot earlier. I reached out to pure water filtration and Brandon got back to me immediately. He gave me a quote over the phone, we scheduled the install three days later and he was very communicative. He was on time, called us when he was on his way and installed the system extremely quickly. This company is fast and effective and they are very professional and courteous. Very glad I called this company, they are awesome. We are in communication with them for a full home filtration system. Thank you, Brandon for your great work and amazing customer service.

Absolutely beautiful job! Brandon was on time, he was very informative on what he was doing, respectful of the property and did his best to be quiet (our baby was napping at the time- she didn't wake up at all during the install!) We absolutely recommend Pure Water Filtration. Invest in treating your home water; your plumbing and your health will thank you.
