Is Radon in Water a Concern in Wilmington, Delaware?

Radon in Water WilmingtonIf you live in Wilmington, Delaware, you are most likely concerned about the quality of the water and air in your home. One of the most dangerous potential contaminants that you should be monitoring is radon, which can infect the water supply in a house.

Radon is a gas that is odorless, colorless and radioactive. It is created when radium decays, and it can be found in the soil and water in many parts of the country. In fact, private wells are more at risk for radon contamination than soil deposits near the surface, so they should be inspected regularly. In sufficient concentrations, radon is a known carcinogen; it is especially likely to cause cancer of the lungs when a person inhales the radon in water that escapes from a house’s water supply into the air.

Radon in Water and Its Risks

Radon in water may get into the air from contaminated water during activities like showering, washing clothes and other ordinary water-related tasks. The U.S. Environmental Protection Agency recommends maintaining standards for radon in water of up to 300 pCi/L for public water supplies, according to the Safe Drinking Water Act. However, many have found radon levels in their own water supplies far above this level — especially in homes that are supplied by private wells.

Wilmington is in New Castle County; recent testing shows that the average indoor radon levels in the air in this county are 2.7 pCi/L. This is below the accepted safety cutoff of 4.0 pCi/L, according to the EPA. However, studies of the radon levels in a selection of homes and apartments in Wilmington have shown that about 10 percent of them do contain potentially dangerous radon levels. To make sure that this does not happen to you, be sure to have your home tested if you live in this area.

How Can Radon in Water be Removed from Your House?

Radon in your home could come from either the ground around the house or from the water supplied to it. If you are worried about radon, especially if you own a well, you should have SWAT Environmental test both the air and the water. A different type of test will be required for each.

Radon is not usually a problem from a public water system due to the fact that the water there is treated and processed so that any radon that may exist is released into the air through the processing plant’s aeration system — although there can be exceptions. Private wells, however, can often be contaminated with radon.

Radon in water can be removed through a variety of mitigation processes; SWAT Environmental’s radon experts can determine which is best for your situation. Possible options to protect your home include the installation of specialized aeration systems or granular activated carbon (GAC) filtration systems. Do not attempt to deal with waterborne radon on your own; the risk to your health and that of your family is too high.
