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 upperoccurrence concentration which would produce a maximum product water level at the MCL.
