How can INDA help the wastewater industry… its ratepayers… and its consumers? • Real lab testing is needed • Not just a problem for SCAP members and California agencies • Non woven product “re-formulation” needed? • “Compounds of concern” in nonwovens? • Improved labeling for consumersand industrial users
