Got the news yesterday that a routine water test from a residential spigot not 5 blocks from my house tested positive for E. coli. Of course I'm taking all the precautions I can, but I'm curious if E. coli can affect my tank any? I haven't made any water in 2 weeks, so my current top off supply should be ok. The research I've done so far says that a standard (non industrial) RO/DI unit will NOT remove E. coli from the water supply, and that while its not an ideal environment, E. coli can survive in saltwater. Has anyone ever dealt with this before?
