Well Production Testing

Before purchasing a property, it is important to know as much as possible about the condition of a well, how much water it naturally produces, the overall condition of existing equipment, and the quality of the water it produces. GPM Well Testing 707-823-4102

  • An evaluation of the condition of existing equipment

Water Quality Sampling

Knowing the quality of your water is important to your family’s health and that of your landscaping and crops. For this reason, we strongly recommend that our clients have their water tested at the well and after it passes through the system’s filters. GPM Well Testing will collect and deliver your water samples to a state certified laboratory.

Well Chlorination—Shocking

This is a method used to disinfect a well that has bacterial contamination. We take special care to chlorinate the well water and to circulate the disinfectant through the well casing and pipes. After 12-24 hours we return to pump the system clean. Water CANNOT be used at any time during the shocking process. Sonoma County Department of Health services recommends a follow up bacteria test in 7-10 days.

 

Special Equipment

Our equipment includes a generator for jobs in which other power sources are unavailable. We also have the capability of installing a temporary submersible pump in a shallow well (up to 130' deep) for testing purposes. If a deeper setting is needed, we can arrange for the appropriate equipment.
