Water Quality

What We Do

Our water quality program provides bacterial testing for drinking water and irrigation water samples. We offer water testing in our Regional Lab Monday through Thursday.

We also inspect public and semi-public pools and spas in Mesa County on an annual basis.

  • Coliform – Present/Absent with E. coli ($20)
  • E. coli – Enumerated ($22)
  • Heterotrophic Plate Count ($24)

Payment is due at time of service. We accept cash, check, or credit card.

Buying or selling a home can be a lengthy and confusing process. For homes with a private well, many lending institutions require the well to pass a water quality test before the loan will be approved. Sometimes, these requirements are not known until the last minute and testing can cause a delay for the seller or the buyer. Having the well water tested reassures the buyer, and the value of the home is increased when there is safe drinking water available.

The Regional Lab offers affordable testing with results available the following day via email to all involved parties, per request.

Swimming pools, water parks, hot tubs, lakes, rivers, and the ocean can carry bacteria and make you sick. Do you have a Recreational Water Illness? Seek medical care if symptoms become unmanageable.

We inspect all the public pools and spas in Mesa County. File a complaint by clicking the Contact Us link in the footer below.

MCPH recommends private wells be tested seasonally for bacteriological contaminants. The Coliform test will show whether or not your well or cistern water contains bacteria.

If polluted ground water is consumed, it could cause illness. Ground water pollution can be caused by seepage through landfills, failed septic tanks, underground fuel tanks, fertilizers and pesticides, as well as runoff from urban areas. Testing your water ensures the health of you and your family.

Monday – Thursday from 8 a.m. to 5 p.m.

Please note, the lab is closed on all federal holidays and does not accept water samples the business day before a holiday (or the Thursday before a holiday that falls on a Friday).
