ASSE 6040 case studies
ASSE 6040 · Put your knowledge to work in context.
ASSE 6040 - the Cross-Connection Control Program Specialist credential - is a professional qualification aimed at the people who run drinking-water protection programs rather than at the tester who simply hangs a gauge on a valve. Typical candidates administer backflow prevention programs for municipal water utilities, campuses, hospitals, military installations, and large industrial sites: they decide which premises need isolation, review site hazard surveys, approve assembly selections, track annual testing, manage tester qualifications, and answer to regulators after a contamination incident. The ASSE 6040 case studies are 5 cases and about 2,994 words.
