These deposits can serve as sources to ground and surface waters, especially when in contact with low total dissolved solids (TDS) and acidic waters. Water-soluble barium compounds include salts of acetate, hydroxide, silicate, chlorate, nitrate, thiocyanate, cyanide, oxide and halides (excluding fluoride); salts of arsenate, carbonate, citrate, fluoride, oxalate, and tartrate are only slightly soluble in water but are soluble in acids. Brook and Holmes (16) recommend barium cyanide as the precipitant, but experiments have shown that barium chloride or nitrate is equally satisfactory. High pH causes a bitter taste; water pipes and water-using appliances become encrusted; depresses the effectiveness of the disinfection of chlorine, thereby causing the need for additional chlorine when pH is high.

Low levels of certain barium compounds may have no effects on public health whatsoever. . Most barium compounds are colorless. According to the Water Quality Association (WQA), barium exposure is known to have the following human health effects: Different barium compounds have their own specific health effects. Because hydrogen sulfide is a gas dissolved in water that can easily escape or be lost from the sample, a water sample must be chemically stabilized immediately after collection in order for the laboratory to accurately measure its concentration. The solubility of barium compounds increases under low-pH conditions, meaning that higher . From here, barium may enter drinking water sources through surface runoff. A compound is considered water soluble if it dissolves to the extent of at least three percent. Possible carcinogen. [OH-]. Most barium compounds are colorless. Represented on a scale of 0-14 where 0 is the most acidic, 14 is the most alkaline, and 7 is neutral. Enters environment from natural weathering, industrial production, municipal waste disposal, and manufacturing of flame retardants, ceramics, glass, batteries, fireworks, and explosives.

We know now that barium occurs naturally and is an alkaline earth metal. 2) How is water quality changing over time? Commercial pesticide applicators, farmers, and homeowners apply about 1 billion pounds of pesticides annually to agricultural land, non-crop land, and urban areas throughout the United States. Barium is a divalent cation and alkaline earth metal that can be found in naturally occurring mineral deposits. According to an EPA document, barium is found in low levels in most groundwater and surface water sources, typically less than 0.34 mg/L. Gradually decomposed by water and rapidly decomposed by acids to give off hydrogen cyanide, a flammable poison gas. Because of great economic value of silver, recovery practices are typically used to minimize loss. 3090 Xc3 Review, This draft guideline technical document proposes a new maximum acceptable concentration (MAC) of 2.0 mg/L (2,000 g/L) for barium in drinking water, based on kidney effects in male mice. A carcinogen. Causes crippling bone disorder (calcification of the bones and joints) at very high levels.
