This module gives an example of items that you and the drilling contractor should discuss and agree to before starting any water well drilling. An effective monitoring program will identify changes in water levels and water quality. This module outlines how to measure water levels and water quality on an ongoing basis. A water well monitoring worksheet is included. This module outlines the importance of well maintenance.
Shock chlorination is used to control bacteria in water wells.
Uncontrolled, bacteria can cause reduced well yield, restricted water flow, staining, odors and plugging of water treatment equipment. There are many causes of water well problems. This module outlines some of the more basic causes and provides a troubleshooting guide. The troubleshooting guide identifies four symptoms reduced well yield, sediment in the water, change in water quality and spurting household taps and explains what to check for and how to correct the problem. Once a well is contaminated, it is difficult to remove the contaminant from the well.
