Well Water Quality Testing & Inspections

Your #1 choice for all water quality testing and well water inspection services.

Colorado homes utilize wells in many areas and Well Water Testing is essential to these homes. Ensuring your water quality is high and your well-pump is working at optimal capacity is important for your health and your 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.

What If The Well Tests Positive?

Well Water Testing can find many problems but  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 do well water testing to find out whether your water is a concern for Radon. 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.
  • The lab cannot accept Radon Test samples Thursday afternoon, and at no time on Friday, Saturday, or Sunday.
  • The samples must be delivered to the lab within 24 hours of collection.
