Colorado homes utilize wells in many areas; ensuring your water quality is high and your well-pump is working at optimal capacity is important for your health and you pocket. Make sure your water is not contaminated and that your pump is functioning properly by getting our well-water flow test and lab samples taken.

We will test that the pump operates at an acceptable capacity for an extended period of time, i.e. 2 hours. We do this by measuring the time in which it takes the well to fill a 5-gallon bucket for two hours. This gives us an estimate wherein we can then provide you with information on your well-pump’s functionality. It also lets us know whether there may be a crack in your pump or any other issues.

Domestic Water Sample Reports Include:

  • Total Alkalinity (mg/L as CaCo3)
  • Bicarbonate (mg/L)
  • Carbonate (mg/L)
  • Chloride (mg/L)
  • Iron (mg/L)
  • Fluoride (mg/L)
  • Potassium (mg/L)
  • Nitrate Nitrogen (mg/L)
  • pH (units)


  • Calcium (mg/L)
  • Magnesium (mg/L)
  • Sodium (mg/L)
  • Sodium Adsorption Ration (units)
  • Total Hardness (mg/L as CaCO3)
  • Sulfate (mg/L)
  • Total Dissolved Solids(mg/L)

*mg/L = Milligrams Per Liter or PPM

What If The Well Tests Positive?


Some problems can be handled quickly. For example, high bacteria concentrations can sometimes be controlled by disinfecting a well. Filters or other on-site treatment processes may also remove some contaminants. Other problems may require a new source of water, or a new, deeper well. If serious problems persist, you may need to rely on bottled water until a new water source can be obtained.

Radon Water Test


If you have tested the air in your home and found a radon problem, you may also want to find out whether your water is a concern. If you get water from a public water system, find out whether the comes from a surface (river, lake, or reservoir) or a ground water (underground) source. If you have a private well, the EPA recommends testing your water for radon.

BE AWARE:  These collection times are different from the Domestic Water Quality & the Coliform Bacteria Water tests.

  • Time your sample collection so that the samples are delivered to the lab no later than Thursday, before 12PM.
  • The lab can accept Radon Test samples during open hours on Monday, Tuesday, and Wednesday.
