Because of the importance of groundwater to Mississippi, protecting the underground water supplies, or aquifers, is critically important. Wellhead protection, or well protection, is also important to all well owners in the state. The proper construction of wells is only one aspect of groundwater protection that is monitored and should be insisted on by the public. The Office of Land and Water Resources regulates wells that are not used for drinking-water supplies. The Department of Health and Environment regulates those wells, public and private, that supply drinking water.
Additional standards apply for other types of wells, including municipal supply wells.
Ending the well casing above the 100-year flood level. However, if flood levels around the well routinely exceed a reasonable height for an extended casing, then the well must be protected against the flow of floodwater into the casing. Protecting all wells from the intentional or accidental entrance of contaminants. If the casing is not covered with a continuous recorder box or pump housing, then it must have a locked, overlapping cover capable of preventing contaminants from getting into the well. The grout must be from a depth of at least 50 feet below the land surface, except as specified in number 7 below.
