    2020-7-15 · Beryllium in Drinking Water Beryllium occurs naturally in New Hampshire's bedrock geology. As such, it can dissolve into water and be present in the water from bedrock (artesian) wells. Beryllium has no taste, color or odor, and thus the only way to determine its presence and concentration in drinking water is by laboratory analysis.

    2017-4-25 · Beryllium is a metallic element, it dissolves in water, and it can occur naturally in formations of bedrock. As a result, drinking water that is sourced from bedrock water wells may have Beryllium present. Unfortunately, Beryllium has no discernable color, taste or odor and it cannot be detected without laboratory testing.
