Abstract
Monofluorophosphate salts, especially sodium monofluorophosphate (Na.sub.2 PO.sub.3 F), when added to potable water sources in concentrations between 0.1 mg/L and 500 mg/L, significantly reduces lead (Pb) leaching into said water, producing the double benefit of reducing lead solubility and thus content in drinking water, while at the same time adding fluoride to that drinking water, with the anticaries benefit that fluoridation provides.
