Because of the potential toxicity of lead and its deleterious effects on human health, increased attention has been given to the use of lead piping materials in household plumbing. Water that is corrosive to lead has been observed to leach considerable amounts of lead from pipes, especially after the water has been standing in the pipes for several hours. This paper presents a revised model showing the detailed response of the theoretical solubility curves for lead to changes in dissolved inorganic carbonate concentration ( C t ) and pH at 25°C. The model agrees well with previously published pipe loop solubility experimental data as well as with pipe coupon tests and precipitation data at high C t .
