Notes

Request any (up to three (3)) of these analytes together.

Alternatively request IMIS Code Q115 and SLTC will report any significant amounts of these analytes.

Results for unrequested analytes in this group will be reported if significant amount are found.

Toluene, sec-Butyl Acetate, Benzene and Isobutyl Alcohol all have/are known interferences. Please indicate on the 91A which of these compounds are known to be present.

There is no need to contact SLTC before sampling.
