National Water Service

High levels of acidic water can turn into a serious problem for your plumbing. Water with high acid content causes corrosion to your plumbing which can lead to leaks or floods. In addition, it will corrode and cause green and blue stains to form on your fixtures. To counteract this, a calcite filled acid neutralizer can be installed. The calcite in the Neutralizer injects reactive magnesium oxide into the water supply which dissolves into the water and neutralizes the acidity.

National Water Service installs and maintains Birm Systems that naturally remove iron and manganese without chemicals. Using oxygen already present in the water, these systems eliminate staining, metallic taste, and odor — keeping your water fresh and crystal clear.

Radon is a naturally occurring radioactive gas and comes from the natural breakdown or radioactive decay of uranium. It is usually found in igneous rock and soil, however well water may also be a source of radon. Radon is measured in Pico Curies per Liter (pc/L). The EPA recommends that homes with Radon levels of 4 pc/L in the air have remediation installed in the home. 10,000 pc/L of radon in water adds 1 pc/L to radon in the air. Levels below 4 pc/L of radon in the air still pose a significant health risk according to the EPA, Centers for Disease Control, the American Lung Association and the American Medical Association. Radon is the leading natural cause of lung cancer in the US and the sixth leading cause of all types of cancers. In the past year alone, we have found very high levels (up to 60,000 pCi/L) of radon in wells all around the Washington and Baltimore Metro Regions, specifically in Montgomery and Howard Counties, in Maryland.
