Frequently Asked Questions
When should I have my well water tested?
The National Ground Water Association (NGWA) recommends well owners test their water at least annually for bacteria, nitrates, and any contaminants of local concern. More frequent testing should be considered if:
- 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.
What can impact groundwater quality?
Forty-seven percent of the United States depend on groundwater for their basic drinking water supply. Having a basic understanding about groundwater quality will help ensure that your well is supplying potable water for your household.
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.

Properly constructed and maintained water well systems are designed to keep microorganisms such as bacteria, viruses, and protozoa from getting inside the well system and into the water. When a water test indicates the presence of microorganisms in a well, disinfection of the well system is recommended along with some level of inspection.

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.
Maryland 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 2.683 persons per household. The USGS estimates the population of self-supplied water supply users in Maryland to be 1,420,000, all of which use groundwater.
- 396 community water systems use groundwater for 959,000 people
- 539 non-community, non-transient water systems use groundwater for 149,000 people
- 2,260 non-community, transient water systems use groundwater for 331,400 people
- 1,520 irrigation wells used serving 600 farms and 78,700 acres
