While Denton tap water is generally considered safe to drink, there are a number of contaminants present that may not exceed federal guidelines. This can includes nitrates, radiological contamination such as radium, and disinfection byproducts such as bromate, bromodichloromethane, chloroform, dibromochloromethane and dichloroacetic acid. There have been recent drought concerns. In August 2024, Denton implemented Stage Two of its Drought Contingency Plan due to water treatment capacity concerns. Residents were limited to outdoor irrigation once per week.

There is no reported hardness level in Denton’s recent tap water quality report, but it is widely considered to be hard water. Unsubstantiated reports show water hardness to be more than 200mg/L.

Recent sampling conducted at Denton’s water treatment plants 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, many samples do not meet these standards. Click here to learn more about our whole house PFAS filtration systems.

Yes, Denton adds fluoride to its water supply to help prevent tooth decay. The most recent water quality report showed an max level of .22 parts-per-million. The maximum contaminant level is 4 ppm.

Denton sources its drinking water from Lake Lewisville and Lake Ray Roberts, both surface water reservoirs. The City of Denton Water Utilities treats this water to ensure it meets or exceeds federal and state safety standards.

With reported hardness levels of more than 200 mg/L, which is considered hard, it is advised for your home to have a water softener to save on appliance costs, better your clothing, improve your hair and skin, and other benefits. Learn more here.

Denton, Texas water contains levels of nitrates, radium and other radioactive contamination, as well as HAA5, TTHMs and other disinfectant byproducts from chlorine or chloramine treatment.
