| Details: | SUMMARY: pH minimum is not met DETAILS: Lab staff measured pH in field at entry point, cafeteria, and gym. Readings were 5.97, 6.20, and 5.98, respectively, and confirmed by lab values. Thus, corrosion control treatment is not being operated correctly. This puts into question whether past readings from PWS are accurate, and thus a pH of 7.2 may in fact be adequate for optimal corrosion control. ACTION NEEDED: Lane County to query operator about pH measurements accuracy. | ||
