  • There is a change in the taste, odor, or appearance of the well water, or if a problem occurs such as a broken well cap, inundation by floodwaters, or a new contamination source
  • The well has a history of bacterial contamination
  • The septic system has recently malfunctioned
  • Family members or house guests have recurrent incidents of gastrointestinal illness
  • An infant is living in the home, or
  • To monitor the efficiency and performance of home water treatment equipment.

Along with human activities, water quality is affected by a combination of natural processes. Most relate to chemical compositions underground. However, other factors such as biological, physical, and radiological conditions can affect water quality as well.

Louisiana Groundwater and Water Well Statistics

Few states can accurately or confidentially determine how many residential wells are in place. For each region, the American Housing Survey by the U.S. Census provides regional data.

Louisiana is found in the South, along with these other states: Maryland, Delaware, Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Texas, Oklahoma, Arkansas, Tennessee, and Kentucky.

The last American Housing Survey Census indicates this region had 4,360,0002 households served by residential wells, with an average of 2.63 persons per household. The USGS estimates the population of self-supplied water supply users in Louisiana to be 492,000, all of whom use groundwater.

  • 906 community water systems use groundwater for 3,164,000 people
  • 116 non-community, non-transient water systems use groundwater for 48,900 people
  • 225 non-community, transient water systems use groundwater for 49,000 people
  • 8,550 irrigation wells used serving 1,600 farms and 883,000 acres
