Initially 5-10 "Worse case" sites associated with each use industry should be selected for monitoring similar to that done at manufacturing facilities. Monitoring should be designed to provide scoping baseline data to inform future site selection ifneeded, and to allow qualification efforts to reduce releases.

Screening level study design is site/industry dependant, but may include: 5-10 surface water samples upstream, at the site, and downstream, 620 wells with quarterly groundwater sampling, 5-10 air samples, monthly wastewater sampling, quarterly sludge sampling if discharges go to POTW, 20-50 soil samples, 20-50 biota samples Surface water, groundwater wastewater, air, soil, biota (plants, herbivores, avian terrestrial species) monitoring studies around use facilities Data to characterize environmental concentration away from use site and to identify limit of environmental contamination Wastewater and sludges from POTWs receiving discharge from user facilities should be included -4-
