The aquifer goes from Martha’s Vineyard to New Jersey plus they are looking into tapping it.

OK, but on the east cost, there is no shortage. I believe the only issue is the throughput of water treatment, local governments unwilling to maintain and build plants. Many of these plants are over 50 years old and only been maintained using duct tape and bandaids ;)

So where would this water go, plus how with will it be treated or are they assuming it is "pure" and just pass it on without treatment ?
