El Paso County sits at the western tip of Texas, home to about 870,000 residents in one of the driest metro areas in the country. El Paso Water draws from the Rio Grande, the Hueco Bolson aquifer, and the Mesilla Bolson aquifer. The utility has become a national leader in water reuse, operating the Kay Bailey Hutchison Desalination Plant – the largest inland desalination facility in the world – which treats brackish groundwater that was previously unusable.
El Paso's water story is one of scarcity driving innovation. The Hueco Bolson aquifer has been overdrawn for decades, and saltwater intrusion has degraded water quality in portions of the aquifer. The desalination plant, which can produce 27.5 million gallons per day, treats this degraded groundwater into drinking-quality water.
UCMR5 data shows PFAS detections in the El Paso Water system. Fort Bliss, one of the largest military installations in the country, has documented AFFF use and PFAS contamination in surrounding groundwater. According to the TCEQ's 2024 monitoring data, PFAS levels in the municipal system were below federal action thresholds, but ongoing military remediation at Fort Bliss continues.
El Paso Water's desalination and advanced treatment infrastructure provides a level of contaminant removal that many conventional systems cannot match. But neighborhoods near Fort Bliss may face elevated PFAS through private wells or localized groundwater.
