Allen, Texas's Home for Water Softeners, Water Filters,
& Water Delivery

The Environmental Working Group (EWG) has identified 19 contaminants in Allen’s water supply that exceed their health guidelines, based on data from 2014 to 2020. It’s important to note that EWG’s health guidelines are often more stringent than federal standards. The detected contaminants include cyanide, detected at it’s highest level of 199 at the Wylie Water Treatment Plant, barely below the EPA limit of 200 parts-per-billion. Cyanide is a toxic chemical that can cause central nervous system and thyroid toxicity.This is caused by discharge from steel, metal, plastic, and fertilizer factories.

The most recent Allen Water Quality Report showed a range of hardness of 82 to 312 parts-per-million, which is considered moderately hard to extremely hard.

Recent sampling conducted at Allen’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, Allen adds fluoride to its water supply to help prevent tooth decay. The most recent water quality report showed a range of levels from .537 to .968. The EPA maximum contaminant level is 4 ppm.

Allen, Texas, receives its water supply from the North Texas Municipal Water District (NTMWD). The NTMWD primarily sources water from Lavon Lake, which is located just northeast of Allen. Lavon Lake is one of the main reservoirs in the area, providing water to multiple communities in North Texas.

With a hardness that can be as high as 312 parts-per-million, which is considered very 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.

In addition to levels of cyanide, Allen, 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. While none of these are typically above the EPA maximum contaminant level, they could be harmful.
