Broomfield’s water quality surpasses state and federal standards for drinking water, according to a new water quality report published by the city and county. 

Broomfield water treatment staff performed more than 25,000 tests in 2021 for approximately 100 contaminants that are regulated by the government, including for substances like arsenic, barium, chromium and nitrate. 

“We are meeting all of the water quality standards and just have excellent quality of water,” said Laura Hubbard, environmental services laboratory supervisor for the city and county.

The city and county conducted 107 tests for lead and copper at the taps in Broomfield homes, according to Hubbard.

Of those, two homes were above the “action level” of 15 parts per billion, while 90% of the tests were 3.8 parts per billion or lower. 

Lead in drinking water is typically caused by corrosion of household plumbing, Hubbard said.

When water from a home tap in Broomfield tests above the action level, city and county staff discuss possible sources with residents, such as at faucets, shutoff valves or soldering on copper pipes. Broomfield offers free follow-up water testing after residents have acted to mitigate the source of lead in their water, Hubbard said. 

The city and county also conducts tests for pH levels, minerals, water hardness, disinfection byproducts and turbidity. 

Broomfield has never violated a “maximum contaminant level” for water quality, according to the report.
