How is radium treated in private wells?
Of the treatment methods described earlier, ion exchange using zeolite softening is effective for home use. Radium, however, could get past a softener which is improperly maintained. Owners need to check softeners regularly to assure that they are operating properly. These home units also build up wastes that need to be properly disposed, and will increase sodium levels in water. Small “reverse osmosis” units and distillation units may be effective in radium removal in home systems, but the units have limited capacity and severely restrict water flow. The devices can only be used to treat water from a single faucet rather than the entire water supply. Additionally, other water quality problems such as high iron or manganese may interfere with these treatment methods. The Department of Industry, Labor and Human Relations must approve in-home treatment units for radium removal. The DNR must approve the treatment process and each installation.
