Details: SUMMARY: Hand feeding chlorine DETAILS: Jim spoke to James Nusrala about low flow in-line ultrafiltration units for collodial iron removal. James explained the plan review process. During this time it was noted that the most recent coliform sample had a chlorine result of 5.6ppm. Jim started hand feeding the chlorine a couple of years ago because they could not maintain the chlorine residual with the pump and usage. I emailed Jim and explained that we could no longer allow them to hand feed the chlorine. The levels were all over the board. Jim responded that they spoke to the feeder pump people and they assured him that the new pumps would be able to maintain the residual better than before. They are planning on installing the pump tomorrow. ACTION NEEDED: none
