What about showering night before? Cologne? Soap? Detergents? Shoe materials? So many items have PFAS... protocols have changed since this video I think.
Is your shirt PFAS free? Is the chlorine residual recorded as Free or Total chlorine? And should you not take a field reading of both free and total chlorine and record both results on the COC?
Incredibly helpful.
