Yes. Arvada’s drinking water meets federal and state drinking water standards. The city completes required testing for regulated contaminants, and results are reviewed to confirm compliance with Safe Drinking Water Act requirements.

Yes. Arvada’s tap water is considered moderately hard. Average total hardness measured at the Arvada Water Treatment Plant was approximately 69 parts per million (ppm) as calcium carbonate, with seasonal fluctuations ranging from 43–85 ppm. Water in this range can contribute to mineral scale buildup on plumbing, fixtures, and appliances over time, especially in water heaters, dishwashers, and boilers.

Recent sampling for Arvada, Colorado drinking water detected the presence of PFAS chemicals. The EPA is in the process of setting new maximum contaminant levels (MCLs), which range from 4 to 10 parts per trillion, equal to 0.00000000004 for PFOA and PFOS individually, and up to 0.0000000001 for PFNA, PFHxS, and HFPO-DA (GenX Chemicals). As you can see in the water quality report, many samples do not meet these standards. Click here to learn more about our whole house PFAS filtration systems.

Yes. Fluoride is present at an average level of approximately 0.56 ppm, which is well below the EPA maximum contaminant level of 4.0 ppm and within recommended levels for dental health.

Arvada’s drinking water comes primarily from Denver Water’s North System and Clear Creek, sourced from high-country snowmelt collected from the Fraser River and South Boulder Creek basins, stored in mountain reservoirs, and treated before distribution throughout the city.

Arvada’s water is treated using multi-step processes including coagulation, sedimentation, filtration, and chlorine disinfection, along with turbidity control and organic carbon removal to ensure safe, reliable drinking water.

While Arvada’s water meets all safety standards, many homeowners choose additional treatment to reduce moderate hardness, minimize scale buildup, and improve drinking water taste and clarity. A water softener can help protect plumbing and appliances from mineral scale, while filtration systems can further improve drinking water taste, odor, and clarity at the tap.

Arvada conducts continuous testing throughout the treatment and distribution system, collecting thousands of samples each year and analyzing over 100 regulated and unregulated parameters at certified laboratories. Monitoring occurs at multiple stages — from source water to finished drinking water and within the distribution system — ensuring ongoing compliance with state and federal drinking water standards and the Safe Drinking Water Act.
