Environmental Health and Water Testing
Environmental Health is the branch of Public Health that seeks to enhance human wellbeing by monitoring and improving environmental conditions. Services provided through Environmental Health aim to promote quality management of natural resources including air, water, and soil, and to maintain the health of the communities that use them.
Water Testing:
Starting July 2024, residential well water tests will include nitrate and nitrite detection at no additional cost.
- Nitrates and nitrites are particularly harmful to pregnant women and young infants as well as those with genetic conditions or reduced stomach acidity. Consuming high amounts of nitrate and or nitrite can cause a condition called methemoglobinemia, which affects the blood’s ability to carry oxygen. Learn more about nitrates and nitrites in drinking water.
- Nitrate and nitrite tests offered through Gilpin County Public Health will only indicate if there are nitrates and or nitrites present in your water. If your test indicates the presence of nitrates and or nitrites, it is strongly recommended to have an additional test done to provide you with an exact level. In the event of a positive nitrate or nitrite test, Gilpin County Public Health will provide you with guidance for further testing.
Gilpin County Public Health has a water quality lab certified by the Colorado Department of Public Health and Environment. It is recommended that all private wells be tested by the owner every year for nitrates, nitrites, and bacteria, which are the most common sources of well water contamination. We can test your well water for the presence of nitrates, nitrites, and total coliform bacteria and E.coli for a $30.00 fee (cash or check only).
To Have Your Well Water Tested:
- Come to our office and pick up a sample bottle and instructions; please follow the instructions carefully. We cannot accept samples that are over or under the fill line.
- Drop off the sample within 24 hours of collection at our office with your payment. We accept cash or checks.
NOTE: Samples are only accepted Mondays, Tuesdays or Wednesdays between the hours of 8:00 am and 4:00 PM. Results will be emailed to you within 48 hours.
If you would like to have further water testing done, we recommend the Colorado Department of Public Health and Environment's (CDPHE) water testing services.
The Golden Water Quality Lab also offers a range of testing options.
FREE PFAS Well Testing
Gilpin County Public Health (GCPH), in partnership with the Colorado Department of Public Health and Environment (CDPHE), is offering free well water testing for per-and polyfluoroalkyl substances (PFAS), a group of chemicals linked to long-term health risks.
For those drinking water from a private well, testing is available through the PFAS Testing and Assistance Program (PFAS TAP) at no cost. You must order a free PFAS kit through CDPHE to be shipped to your home, PFAS testing is not conducted at the Gilpin Public Health water lab. Some participants may also qualify for a free water filter that removes PFAS and other common contaminants. Testing helps identify and minimize exposure to PFAS in the area and develop recommendations on PFAS contamination. This program is available while supplies last.
A public meeting will be held at the Gilpin County Library (15131 Highway 119, Black Hawk, CO 80422) on August 13, 2025, from 6-8 pm to answer questions and share more information about PFAS, the testing program, and other well water quality concerns.
