At yesterday’s meeting of the two water boards, City Council, and the Board of Supervisors, they unanimously rejected the use of chloramines to purify the regional water supply, Lisa Provence reports for The Hook. Faced with a choice between an $18M granular activated carbon filtration system or a $9M chloramine-based system, they were considering adding the ammonia derivative to save $9M. Most public water supplies in the state are purified with chloramines, but the catch is that they can suck the lead right out of old pipes, which is particularly dangerous for children. Concerns about chloramines were widespread, with dozens of people speaking against chloramines at yesterday’s meeting, but nobody speaking in favor of them. Next up: Ginning up another $9M to fund a new carbon filtration system.
