Calabasas Is Your Tap Water Really Safe? What Residents Need to Know About Hidden Contaminants
By The Clean Water Company
If you live in Calabasas, you probably assume your water is clean because it’s treated—but even “safe” water can carry invisible threats. Harmful substances like PFAS, heavy metals, and disinfection byproducts may still be present, and over time, daily exposure can add up.
At The Clean Water Company, we help Calabasas homeowners understand where their water comes from, what it might contain, and how advanced filtration can protect their families and homes.
Who Provides Calabasas’ Water?
Calabasas is served by the Las Virgenes Municipal Water District (LVMWD), which supplies water to over 75,000 people in:
Calabasas
Agoura Hills
Hidden Hills
Parts of Westlake Village
Where Does the Water Come From?
LVMWD doesn’t use local groundwater or reservoirs. Instead, 100% of its drinking water is imported by the Metropolitan Water District of Southern California, which draws from two major sources:
The State Water Project (SWP) – Snowmelt from the Sierra Nevada Mountains in Northern California melts each spring, feeding into rivers, reservoirs, and ultimately the California Aqueduct, which transports water over 400 miles south to Southern California.
The Colorado River Aqueduct – Sourced from the Rocky Mountains, this water begins as snowpack in states like Colorado and Wyoming. It travels through the Colorado River Basin, into Lake Havasu, and is then pumped across the desert into Southern California.
By the time this water reaches your faucet in Calabasas, it has traveled hundreds of miles, been processed multiple times, and passed through a complex web of infrastructure—all before it even hits the pipes in your home.
How Is Calabasas Water Treated?
Water from both sources is treated at facilities such as the Westlake Filtration Plant, using a combination of:
Coagulation & flocculation – Particles clump together for removal
Filtration – Removes fine particles and impurities
Disinfection – Chlorine or chloramine kills pathogens
Ongoing monitoring – Ensures the water meets federal and state standards
But here’s the issue:
Legal limits don’t always equal safe limits. Some contaminants are still present in trace amounts that can build up over time.
What Contaminants Might Be in Calabasas Water?
According to annual water quality reports and environmental watchdogs like the Environmental Working Group (EWG), the following contaminants may be present in trace—but still concerning—amounts:
Disinfection Byproducts (THMs, HAAs) – Linked to increased cancer risk
Chlorine & Chloramine – Can cause dry skin and an unpleasant taste or odor
PFAS ("Forever Chemicals") – Associated with hormone disruption and immune issues
Chromium-6 – A known carcinogen made infamous by the film Erin Brockovich
Heavy Metals (Lead, Arsenic) – Toxic to the brain and harmful during pregnancy
Nitrates/Nitrites – Dangerous for infants and expecting mothers
Hard Water Minerals (Calcium, Magnesium) – Cause limescale buildup and reduce appliance efficiency
✅ Note: These are often found within regulatory limits—but that doesn’t mean they’re risk-free for daily, long-term exposure.
How The Clean Water Company Can Help
We specialize in custom filtration systems specifically designed to address the unique water conditions in Calabasas.
🏠 Whole-Home Filtration Systems
Installed at the point where water enters your home, these systems purify all the water flowing through your pipes—from your showers and sinks to dishwashers and laundry machines.
They’re built to reduce or remove:
Chlorine & chloramine – For better skin, hair, and taste
Disinfection byproducts (THMs, HAAs) – To reduce long-term cancer risks
PFAS – To limit exposure to synthetic industrial chemicals
Heavy metals – Including lead, arsenic, and mercury
Hard water minerals – Using salt-free technology that restructures minerals to prevent scale
Pesticides, herbicides, and VOCs – Common in urban runoff and tap water
🚰 Reverse Osmosis (RO) Systems
Ideal for under-the-sink installation, RO systems provide the purest drinking water possible, removing:
Up to 99% of Total Dissolved Solids (TDS)
Fluoride, PFAS, chromium-6, lead, arsenic, nitrates
Pharmaceutical residues and other micro-contaminants
Perfect for baby formula, coffee, cooking, and pets.
Final Thoughts
Water in Calabasas may be legally “safe,” but that doesn’t mean it’s free from potential health risks. From Sierra snowmelt and Colorado runoff to hundreds of miles of infrastructure and disinfection—your tap water has a long journey, and it picks up more than just minerals along the way.
Protect your family, your home, and your peace of mind.
