El Paso relies on three sources of water supply to meet its potable water supply needs. These three
sources are the Rio Grande for surface water, and Mesilla and Hueco Bolson for groundwater. The arsenic
in the Rio Grande source averages about 4-6 ppb and is largely removed during surface water treatment.
In the Mesilla Bolson, the majority of wells have elevated arsenic levels averaging about 17 ppb and
treatment will be centralized utilizing a different approach under a separate program. In the Hueco
Bolson, the largest aquifer, arsenic is intermittent and spotty. This paper is about the Hueco Bolson
Aquifer and four of its eight well fields (Northeast, Cielo Vista, Eastwood and Lower Valley) impacted
by the Arsenic Rule. The Hueco Bolson is a critical source of drinking water and represents an average
production capacity of 42 mgd and peak sustainable capacity of 50 mgd. Pilot studies conducted by
EPWU indicated that an adsorption media system for arsenic removal would be easy to operate, has
limited residuals handling requirements, minimizes chemical handling and assures process integrity. Includes tables, figures.
