Denver Water Quality

11 of these 34 contaminants are rated as exceeding health guidelines.

Lead in Denver Water

Denver drinking water has lead in it.

90 percent of samples taken from Denver water sources had a lead concentration of 11 parts per billion (ppb) or less.

Lead concentrations of 3.9 ppb to 15 ppb “put a formula-fed baby at risk of elevated blood lead levels.” (

Here are a few of the lead poisoning symptoms for children under 6:

  1. Abdominal Pain
  2. Developmental Delay
  3. Learning Difficulties
  4. Fatigue
  5. Weight loss
  6. Irritability
  7. Hearing loss

There is no safe level of lead for humans.

  • However, the initial cost is higher and they require installation.
