1. Example data provided. The data provided is not representative of actual storm volumes or treatment.
2. I\ on -detect infuent and effluent sample results will be assigned a value of zero for the calculation and the values from duplicate samples will be averaged together,
Acronyms;
< MDL; less than the minimum detection limit
HFPO-DA; hexafluoropropylene oxide dimer acid
PF VIOAA; 2,2-difluoro-2-(trifluoromethoxy) acetic acid
P_VIPA; perfluoromethoxypropyl carboxylic acid
