Wells and Groundwater

From the mountains of Allegany County to the shores of the Chesapeake Bay, well maintenance and groundwater are linked across Maryland. Most residential wells withdraw groundwater that is replenished by rainfall entering the ground within a few miles of the well. For this reason, the way you, your neighbor and those outside your community use the landscape can be an important factor in the quality of your water supply.

What's in your well? 
Test annually to find out!

Here are some ways to keep your water clean, clear and healthy:

  • If you live in a home with a well, YOU are responsible for ensuring its safety and maintenance.  Mark your calendar to have your well tested and inspected yearly.
  • It is recommended that water be tested every year for total coliform bacteria, nitrates, total dissolved solids, and pH levels.
  • If you notice a change in your water, contact your local county health department to arrange for a test or to request a list of State-certified water testing laboratories serving your area.
  • Homeowners with wells should sample any time there is a change in odor, taste or appearance of the water.
  • If you suspect a problem with your water, survey your well and consider making simple changes to stay safe such as having your septic system checked or decreasing the amound of fertilizers or other chemicals used around your well.
