Is lead a concern in El Paso’s Water? There is no lead in the source waters used for El Paso's drinking water, nor is there lead in the pipelines that carry water through the city or the service lines that lead into businesses and homes.
Lead seldom occurs naturally in lakes and rivers, and it is seldom present in water at treatment plants. Lead in drinking water is usually caused by corrosion in water distribution systems and in the lead plumbing fixtures and lead solder commonly used in older homes.
How is lead monitored? EPWater monitors lead levels at its water treatment plants, in the distribution system and in homes likely to have elevated lead levels. Lead is rarely detected, but when it is, levels are very low. The highest level detected recent samples was 80 percent below the limit set by the Environmental Protection Agency.
How do you prevent lead from old home plumbing systems from entering the drinking water? Because river water can be slightly acidic, EPWater adds phosphates to inhibit corrosion. This chemical creates a film in pipes that reduces the likelihood of lead leaching from lead plumbing systems. Water from the aquifers is not acidic, so corrosion inhibitors are not required.
