Barium sulfide slowly decomposes in water, forming barium hydroxide and barium hydrosulfide. It is soluble in concentrated sulfuric acid. Enters environment from industry, mining, plumbing, gasoline, coal, and as a water additive. Pure barium is often used to make components in machinery, such as spark plugs and bearings. You, or other consumers of your water source, exhibit any symptoms outlined in the Health Risks for Barium section above. Most at-home water test kits dont detect barium. Can cause a variety of cardiac, gastrointestinal, and neuromuscular effects. Although HCN is highly soluble in water, its solubility decreases with increased temperature and under highly saline conditions. Thus, having reliably clean groundwater is of concern for many throughout the world. Generally, the finer the gold, the quicker it will dissolve. Barium concentrations in drinking water in the United States typically average 0.03 mg/L, but can average as high as 0.302 mg/L.

Barium Cyanide, Ba CN 2, is formed by passing anhydrous hydrocyanic acid over cooled barium hydroxide crystals, and dissolves in the water of crystallisation of the hydrated baryta. Although barite is non-toxic, when it comes in contact with deep water brines existing below the Earths surface that are high in naturally occurring chloride, it converts to barium chloride, which is highly toxic. Brook and Holmes (16) recommend barium cyanide as the precipitant, but experiments have shown that barium chloride or nitrate is equally satisfactory. There are two common barium compounds: barium sulfate and barium carbonate. But, having water flow to the surface naturally is a handy way to tap groundwater resources.

Barium cyanide - Wikipedia pyridinium iodate = HC5H5NIO3. 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. 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).
