The VT DOH recommends testing for gross alpha every 5 years. This test provides insight on the total radioactive concentration of your water supply and will indicate if additional testing is necessary.
FAQ:
What does gross alpha measure?
Gross Alpha is a test that is performed to measure the overall radioactivity in drinking water. Naturally occurring radioactive elements emit alpha particles as they decay. Alpha radiation exists in the soil, in the air, and also in water.
How do you remove gross alpha from water?
Gross Alpha in groundwater can be removed by the use of a water softener (i.e. ion exchange) or reverse osmosis system. The type of system necessary to remove Gross Alpha particles will be based on the underlying constituent (i.e. radium, uranium) contributing to elevated Gross alpha activity.
