What’s Really in Your Water? A Look at Newbury Park & Thousand Oaks Water—and How to Make It Cleaner
By The Clean Water Company
If you live in Newbury Park or Thousand Oaks, you probably assume the water coming out of your tap is clean and safe. And while it does meet federal and state regulations, “legally safe” doesn’t always mean healthy or high-quality. At The Clean Water Company, we believe in going beyond the minimum—because your home and your family deserve better.
Let’s explore where your water comes from, how it’s treated, what contaminants it picks up along the way, and how our whole home and reverse osmosis (RO) systems can provide the cleaner water you’re looking for.
Where Does Your Water Come From?
In Newbury Park and Thousand Oaks, your water has a long journey. It comes from a mix of local groundwater and imported surface water supplied by the Calleguas Municipal Water District (which sources most of its water from the Metropolitan Water District of Southern California).
Most of the imported water originates in two major sources:
1. The Sierra Nevada Snowpack
Snowmelt from the Sierra Nevada mountains feeds into the Feather River, which travels into the Sacramento–San Joaquin Delta in Northern California.
From there, it flows into the California Aqueduct via the State Water Project (SWP), traveling hundreds of miles south.
2. The Colorado River Basin
Snowmelt from the Rocky Mountains in Colorado and Wyoming makes its way into the Colorado River, which is diverted through aqueducts into Southern California.
This water travels through an intricate system of reservoirs, canals, and treatment plants—before arriving at your home via local water infrastructure.
How Is It Treated?
The water is processed by the Metropolitan Water District, and then delivered to local cities via the Calleguas system. Treatment includes:
Initial Filtration – Large particles, sediments, and organic matter are removed.
Chemical Disinfection – Chlorine and chloramine are added to kill pathogens and bacteria.
Fluoridation – In many cases, fluoride is added for dental health.
Distribution – Water travels through miles of pipes, many of which are decades old, before it reaches your tap.
While this process makes water microbiologically safe, it doesn’t eliminate all contaminants—and it introduces a few of its own.
Common Contaminants Found in Local Water
Even after treatment, here’s what can be found in Thousand Oaks and Newbury Park water:
Chlorine & Chloramine – Used to disinfect but can cause skin, hair, and respiratory irritation. Can also react with organic matter to form disinfection byproducts like trihalomethanes (THMs) and haloacetic acids (HAAs).
Hexavalent Chromium (Chromium-6) – Detected in local water at levels that concern health advocates, even if they meet legal limits.
PFAS (Per- and polyfluoroalkyl substances) – “Forever chemicals” linked to cancer and endocrine disruption.
Volatile Organic Compounds (VOCs) – From industrial runoff, paints, and solvents.
Lead and Copper – Can leach into water from aging household plumbing.
Nitrates – From agricultural runoff, especially in groundwater.
