Yes. Broomfield’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.

Broomfield’s tap water is considered moderately hard, with typical hardness levels ranging from 30–130 parts per million (ppm) as calcium carbonate (approximately 1.7–7.7 grains per gallon). This hardness can contribute to mineral scale buildup in plumbing, fixtures, and appliances, reduced soap efficiency, and water spotting on glassware and surfaces.

Recent sampling for Broomfield, Colorado drinking water detected the presence of PFAS chemicals. The EPA is in the process of setting new MCL (maximum contaminant levels), which range from 4 to 10 parts per trillion. In numbers, that would be 0.00000000004 for PFOA and PFOS, individually, to 0.0000000001 for PFNA, PFHxS, and HFPO-DA (GenX Chemicals). As you can see in the water quality report, several samples do not meet these proposed standards, including detections of compounds such as PFBS, PFBA, PFHxA, and PFPeA, while regulated PFAS like PFOA were detected at low parts-per-trillion levels.

Yes. Fluoride is present in Broomfield tap water at typical levels ranging from 0.55 to 0.78 ppm, which is below the EPA maximum contaminant level of 4.0 ppm. Fluoride is added during treatment to help promote strong teeth and reduce the risk of tooth decay.

Broomfield receives drinking water from two primary sources: Broomfield’s Water Treatment Plant and treated water purchased from Denver Water. All drinking water comes from surface water sources, including rivers, lakes, and reservoirs. Water originates from the Colorado and Fraser Rivers west of the Continental Divide and is delivered through the Colorado-Big Thompson (C-BT) Project. On the eastern slope, water is stored in Carter Lake, transported via a 33-mile pipeline, and stored in the Matthew D. Glasser Reservoir before treatment and distribution. Denver Water supplies originate from its extensive Moffat and South Platte River collection systems.

Broomfield’s Water Treatment Plant was upgraded in 2020 and has a treatment capacity of 26 million gallons per day. The multi-step treatment process includes:

Certified operators continuously monitor the treatment process to ensure water quality, consistency, and regulatory compliance.

Although Broomfield’s water meets all safety standards, many homeowners choose additional water treatment due to moderate hardness, taste preferences, and concerns about trace contaminants such as PFAS, chlorine byproducts, and minerals. A water softener can reduce scale buildup, while whole-house or under-sink filtration systems can improve taste, odor, and overall water clarity.

Broomfield operates a comprehensive monitoring program that includes over 25,000 laboratory tests annually, tracking more than 100 regulated drinking water contaminants across source water, treatment facilities, storage tanks, and distribution lines. Testing ensures compliance with federal and state standards for contaminants including metals, disinfection byproducts, bacteria, radionuclides, and emerging substances like PFAS.

In 2022, Broomfield experienced non-health-based monitoring and treatment technique violations, including:
