Ahead of this presentation I surveyed some customers for my high production board shops and of those 4, 3 disposed directly to drain with both the chemical isolation stream and their spent wash charges. This of course is under permit and was with auditing done routinely, typically monthly sampling, and audits done semi-annually by the EH&S service, whether it’s internal or external. The last facility is a super fun site that was designated in 1987 so they continue to drum up their spent wash solution or on site as it is treatment and disposal. The chem iso still goes down to drain.
