For Hydroviv’s assessment of tap water in McAllen, TX, we aggregated water quality test data from McAllen Public Utility, the city’s water provider and the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze.  We cross reference these data with toxicity studies in the scientific and medical literature, and delve into upcoming regulatory changes.  The water filters that we offer at Hydroviv are optimized with these numbers in mind.

Sources Of McAllen Drinking Water

The sources of drinking water used by McAllen Public Utility are Surface Water and Ground Water. Water is received from the Falcon and Amistad Dams, located in Starr and Val Verde Counties, respectively. The water is transferred from the Rio Grande River by irrigation districts into reservoirs. 

Arsenic In McAllen Drinking Water

Arsenic is a toxic metal that is known to cause cancer and other health issues. Unlike lead, which distributes into water from plumbing, arsenic comes from the source water itself. McAllen is in compliance with the EPA’s water quality standards but it’s important to point out that EPA’s standard balances the toxicity against the costs of removing arsenic from drinking water. The city’s most recent tap water quality report reported an average arsenic concentration up to 3 parts per billion. Hydroviv recommends that anyone with more than 1 part per billion take steps to remove arsenic from their water, especially if they have children.  

Chromium 6 Levels In McAllen Drinking Water

Chromium 6 is a highly toxic metal that is not currently regulated by the EPA.  In recent years, the city’s tap water has averaged 7 parts per trillion for Chromium 6.  These levels are well within compliance with federal standards but do carry risks of having negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In McAllen Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter.  Although these chemicals are not currently regulated very well, the EPA has admitted that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.
