I think my point is that the additional water needed for Coupeville will need to come from the Skagit river which is very finite at certain times of year. Yet there are going to be certain water rights in Central Whidbey that have to replaced at the historical rates not a new lower rate where is that water coming from. Within a few years a large potion of the Central Whidbey aquifer is likely to be contaminated by PFOA's it only takes 1 gallon of said substance to contaminate a billion gallons of potable water and put it above current standards which are likely to be tighter further in the future.
It is you who should use some common sense.
