1 These harmonized values were agreed upon by representatives of USEPA and Health Canada for the purpose of evaluating products to the requirements of this Standard.
2 Influent challenge levels are average influent concentrations determined in surrogate qualification testing.
3 Maximum product water level was not observed but was set at the detection limit of the analysis.
4 maximum product water level is set at a value determined in surrogate qualification testing.
5 Chemical reduction percent and maximum product water level calculated at chloroform 95% breakthrough point as determined in surrogate qualification testing.
6 The surrogate test results for heptachlor epoxide demonstrated a 98% reduction. These data were used to calculate an upper occurrence concentration which would produce
a maximum product water level at the MCL.
