Performance Data
1
Influent challenge levels are average influent concentrations determined in surrogate qualification testing.
2
Environmental Protection Agency Maximum Contaminant Level, as required under the Safe Drinking Water Act.
3
Micrograms per Liter, which is equivalent to parts per billion (PPB).
4
Maximum product water level was not observed, but was set at the detection limit of analysis.
5
Maximum product water level is set at a value determined in surrogate qualification testing.
6
Chemical reduction percent and maximum product water level calculated at chloroform 95% breakthrough point, as determined in sur-
rogate qualification testing.
7
The surrogate test results for Heptachlor Epoxide demonstrated a 98% reduction. These data were used to calculate an upper occur-
rence concentration, which would produce a maximum product water level at the MCL.
