Abstract |
The Lead and Copper Rule, implemented in 1991, set a Maximum Contaminant Level (MCL) for soluble lead and copper concentrations in standing water samples obtained from household plumbing. Treatment options, depending upon system characteristics, can sometimes either prove costly, difficult to control, or have negative secondary impacts in the system. Additionally, many small groundwater systems have not been chlorinated in the past. Chlorine is a strong oxidizer, and as such, would be expected to have a negative impact on corrosion rates. New regulations will require disinfection, and this may negatively influence corrosion rates and the concentrations of lead and copper in the drinking water. Increased corrosion of iron and associated consumer complaints are also possible. This study will address corrosion control in small public water systems, with emphasis on responding to the Lead and Copper Rule, and disinfection related problems such as red water and taste and odor complaints from consumers. |
