Compared with other drinking water regulatory
determinations, the cost implications of a perchlorate
maximum contaminant level are relatively low
because of the chemical's limited occurrence in source
waters in the United States. However, a small number
of systems are carrying this cost burden and the cost
implications to an individual system having to install
perchlorate treatment would likely be significant.
Several studies have evaluated the nationwide
occurrence of perchlorate in drinking water
sources, but to the authors' knowledge, no study
has been conducted evaluating the cost implications
for treatment of all perchlorate-contaminated
drinking water sources. This study was undertaken
to bridge this information gap in anticipation of
discussions about whether to regulate perchlorate
at a national level.
If the perchlorate regulation is revisited by the U.S.
Environmental Protection Agency, this study is
expected to be a key building block for subsequent
evaluation of the cost implications of a national
perchlorate standard. This article provides an initial
estimate of costs associated with such a standard.
Details can be used as guidelines for water suppliers
as they assess the cost implications of installing perchlorate
treatment at their utility. Includes 32 references, tables, figures.
