Well Investigation

You may need a pumping test if you need to know the flow, yield or capacity of your well to supply water.

Well casing inspections with down hole video cameras can identify cracks, leaks or broken drive shoes.

Neptune Water Systems Licensed technicians can provide expertise and equipment for simple or complex well investigations to determine well flows for home owner piece of mind, water system design/management, real estate sales, lands development or to meet other well monitoring objectives.

Well flow or aquifer yield testing may be completed for a number of reasons; you may want to: (a) develop land and/or sell a property; (b) buy a property; (c) satisfy the DOE (well records for new well or existing well construction); (d) provide information to evaluate a water supply adequacy/water system design issue for home owners or other clients who require information.

Well yield pumping (draw down and recovery) tests are completed on wells to ensure adequacy of water supplies. Flow tests may be completed to provide flow rates or more complex tests can be performed to address scientific, regulatory or industrial requirements.

What is a professional well flow test?

Typical Well Flow Testing (Pumping/Yield Test) includes:

  • entry to well via removal of well seal, lid or cap;
  • measurement of the static water level and well depth;
  • removal of well owners pumping equipment (if necessary);
  • Installation of a test pump;
  • step-testing the well to determine the proper pumping rate;
  • pumping the well until it is completely evacuated or for a maximum of 1 hour;
  • measuring the recovery of the well for 1 hour or until it has recovered 90% (whichever is longer);
  • replacement of the well owners pump (if necessary);
  • disinfection of the well;
  • replacement of well seal, lid or cap and departure from the well;
  • well assessment (optional);
  • administration and delivery of well test report.

*standard pumping test includes 1 hour pumping and 1 hour recovery. Longer pumping tests may be completed depending on test objectives(e.g., maximum yield tests, evaluating municipal water supplies, etc.).
