What’s in Casper water?

Here are the top 5 chemical compounds in your water and what health issues they can potentially cause:

  1. Bromodichloromethane – Potential effect: Cancer
  2. Chloroform – Potential effect: Cancer
  3. Haloacetic acids (HAA5 and HAA9) – Potential effect: Cancer
  4. Radium – Potential effect: Cancer
  5. Total trihalomethanes – Potential effect: Cancer

These are five of the 27 contaminants analyzed by the Environmental Working Group (ewg.org).

14 of these contaminants are rated as exceeding EWG Health Guidelines.

Does Casper have Lead contamination?

Yes, Casper has lead in its water. The most recent Lead samples collected from 2015 through 2017 showed concentrations up to 1.0 parts per billion (ppb).

The legal limit for lead is 15 parts per billion. Being well-below this level is a good thing.

  • Concentrations between 3.8 ppb and 15 ppb put a formula-fed baby at risk of elevated blood lead levels. Read more about the symptoms of Lead in water.

There is no safe level of lead for humans.

  • The good news is that 99.99% of the lead can be filtered out.
