【 摘 要 】
As you may know, El Paso gets a substantial amount of its water, about fifty percent, from the Rio Grande. We are subject to the same drought conditions that the rest of New Mexico faces in terms of water supply. In order to do something about the situation, we needed to obtain additional water. At the same time, we have an arsenic issue with which to deal. Like many cities in New Mexico, we are faced with a new arsenic standard. I am sure many of you are familiar with this issue. Of the 152 groundwater wells we had at the time the new standard was imposed, our average arsenic concentration was about 12 parts per billion (ppb) in a range of up to about 30 ppb. The problem is that even though the average is 12 ppb, there are some areas of the city that are served by particular wellfields that might have levels as high as 16 ppb. Arsenic is a concern for us.
