Well Water Safety

With its many uses for drinking, recreation, sanitation, hygiene, and industry, water is our most precious global resource. Access to clean and safe water, adequate sanitation, and improved hygiene are critical to sustaining human health and life. Although water is essential for life, it also causes injuries and can spread illness when it is contaminated by disease-causing organisms.

Water from wells needs to be tested at least once a year or when one or several of the following issues are present:

  • There are known problems with well water in your area
  • You have experienced problems near your well (e.g., flooding, land disturbances, and nearby waste disposal sites)
  • You replace or repair any part of your well system
  • You notice a change in water quality (e.g., taste, color, odor)

For more information on testing your well’s water, please call (915) 212-0438. The cost is $23.00 per sample.

For testing of private wells in unincorporated areas of the county you may also contact the El Paso County Public Works Department at (915) 546-2015.
