Oak Bluffs residents told to boil water

The Oak Bluffs Water District declared a "boil water order" at 5:30 last night due to the presence of coliform bacteria in the public water system.

[concerned]

This is happening to offen and needs to be solved.
If valves opening and closing is the problem the maybe they need new seals or valves. I do know is that when coliform gets in the water there is some cross contamination and needs to be tracked down. Lets face it,they just put in all new mains in just a few years ago and this is happening? There is no reason for this to be happening.
SO FIX IT
