Water Resources Chemicals – Dabcoat 22 (DC-22)

The Lead and Copper Rule mandates that the City have a corrosion control program

approved by the Virginia Department of Health. Beginning in the early 1990's, the City performed

extensive sampling from high risk homes for lead and copper. Although the City’s water would

be considered corrosive based on its natural characteristics, the City has never exceeded the lead

and copper limits mandated by the rule. This is attributed to the corrosion inhibitor that is added

to the water. Based on the results of this sampling, the Virginia Department of Health determined

that the City optimized their corrosion control program.

The City has been using the current corrosion inhibitor, Dabcoat 22 (DC-22) for more than

30 years. This corrosion inhibitor was chosen after testing many different products using metal

coupon testing in the distribution system. Any changes to the corrosion inhibitor would require

prior approval of the Health Department. In order for them to approve the change, the City would

need to perform corrosion testing using the new product and would have to perform additional

testing of homes throughout the City. Because of the many complicated reactions that occur in

water, changing any treatment chemicals can have a negative impact. In the case of corrosion

inhibitors, the City risks not only using a product that doesn't work as well, but it could cause

years of protective coating to come off the distribution piping and actually cause corrosion in the

system.

Due to the sensitivity of this chemical, the City of Lynchburg intends to award Sterling

Water Technologies, PO Box 602, Columbia, Tennessee, 38402-0602 the sole source contract for

the purchase of Dabcoat 22. This is a specially formulated chemical which has proven effective

to inhibit corrosion in the water system. The estimated annual expenditure is $56,000.00 at an

initial cost of $1.405/lb.
