Leakage from septic tanks and/or waste-disposal sites also can introduce bacteria to the water, and pesticides and fertilizers that seep into farmed soil can eventually end up in water drawn from a well. (L96, L214) Health Effects: The health effects of the different barium compounds depend on how well the compound dissolves in water or the stomach contents. The type of barium, how well these compounds dissolve in water, and the subsequent barium concentrations found in water determine the health effects youll experience. barium chloride is more water soluble and more dangerous than barium carbonate), and the waters alkalinity (decreasing pH increases the potential for barium contamination). The health risks posed by these compounds is directly proportionate to their solubility in water; the more easily they dissolve in water the greater health risk they present. If your water does have elevated levels of barium, a short-term solution could be to install a point-of-use water treatment system that removes barium and other cations (positively charged ions), such as calcium, magnesium, sodium, and potassium, systems such as an ion exchange system(IE), water softener (Softener), or reverse osmosis system (RO).
