Influent challenge levels are average influent concentrations determined in surrogate qualification testing.
k
Micrograms per liter, which is equivalent to parts per billion (PPB).
l
Maximum product water level was not observed, but set at the detection limit of the analysis.
m
Maximum product water level set at a value determined in surrogate qualification testing.
n
Chemical reduction percent and maximum product water level calculated at chloroform 95% breakthrough point,
as determined in surrogate qualification testing.
o
The surrogate test results for Heptachlor Epoxide demonstrated a 98% reduction. These data were used to cal-
culate an upper occurrence concentration, which would produce a maximum product water level at the MCL.
p
Environmental Protection Agency maximum contaminant level as required under the Safe Drinking Water Act.
