| Details: | SUMMARY: Update on membrane replacement and corrosion control DETAILS: Chris sent a draft of the lead public education brochure for me to review, I sent back my comments and he hopes to mail it out to users within the next few days. They were able to get some used Polymem membranes from Rockaway Beach and install them-- they are working well and water production is much improved. They were also able to pass a PDT which is great-- they are conducting a PDT daily again and I asked him to notify me if they are unable to pass one again. They are still planning on doing the retrofit with new membranes project, maybe also new media for pretreatment filters and possible coagulation (discussed plan review). New tank is planned to be constructed in July, discussed need for plan review. ACTION NEEDED: Distribute lead education to users this week. Have lab do WQP and source water testing for purposes of corrosion control treatment determination. Submit plans for review for membrane retrofit, corrosion control treatment, pre-membrane treatment, and new tank. | ||
