Like many contaminants in drinking water, barium is potentially hazardous at levels that do not impart a noticeable taste, odor, or appearance to the water. Below are publications associated with groundwater contamination. Although HCN is highly soluble in water, its solubility decreases with increased temperature and under highly saline conditions. Hydrofluoric acid, HF, a weak acid, will react with sodium hydroxide, NaOH, a strong base, to produce aqueous sodium fluoride, NaF, and water. In the surface water pathway, the HWIR modeling scenario includes several transport processes that require metal partition coefficients: (1) The overland transport of metal contaminants in runoff water in the watershed and the consequent partitioning between soil and water; (2) partitioning between It is also hygroscopic, converting first to the dihydrate BaCl 2 (H 2 O) 2.
