(Alden, N.Y.) As the damage estimate from Tuesday's powerful earthquake in Virginia is calculated, experts worry seismic waves may have damaged underground water wells.
Tremors from earthquakes can affect water wells up to thousands of miles away.
The National Ground Water Association (NGWA) issued an advisory for land owners with water wells.
Symptoms of a damaged water well include, fluctuations in water levels, a decrease in water quality, and a change in the well's production.
The National Ground Water Association recommends calling a expert to evaluate the water well if there are problems.
