A personal note from the
heavy heart, the death of Carol Tate of MWH is reported.
A quality person, a good friend, an outstanding engineer,
and a trailblazer for women in engineering and water
quality, Carol will be remembered at a memorial service

EPA's request, the OIG dropped its recommendation
that EPA consider changing from a
"one size fits all" to a "regionalized"
regulatory approach. "EPA stated that while potential
occurrence and related exposure to a contaminant
may vary by region, the health effects do not. EPA develops
regulations to protect the public from potential health risks... regardless
of where they are or the size of the system. In doing so,
regulations are established that are risk-based,
as opposed to a
"one size fits all"
approach." (p. 13 of report)

with the estimate that private bedrock

with the significant number
of wells that have arsenic above the EPA MCL

such analyses. However,
