Arsenic occurs naturally in certain rock formations and can leach into groundwater. It can also come from industrial runoff, mining operations, and agricultural chemicals.
Irving draws its drinking water from groundwater sources (wells and aquifers). The city is served by 1 water system, including LAKE ALAN HENRY BOAT & RV PARK.
Because Irving uses groundwater sources, it may be more susceptible to naturally occurring arsenic that leaches from underground rock formations and soil.
Arsenic levels in Irving's water exceed the EPA maximum at 0.011 mg/L (110.0% of the allowed limit). Immediate water filtration is strongly recommended for all residents. Consider using bottled water for drinking and cooking until an effective filtration system is in place.
The following filtration methods are proven effective at reducing or removing arsenic from drinking water:
Reverse Osmosis
Specialty Adsorption Media
Distillation
When choosing a filter, look for NSF/ANSI certification specific to arsenic removal. Not all filters are equally effective, and certification ensures the product has been independently tested.

For whole-house protection, a point-of-entry system can treat all water entering your home.
