This is the best, you're right on the water source from the nature. I believe it has been in fact reported that even if not all water, some water from some water companies in the DR are in fact potable/drinkable when they left the filtering/preparation facilities, but the state of the plumbing infrastructure in the DR and more importantly, the lack of constant pressure may destroy the quality on the way to the end users/customers. So Coraaplata and others would actually produce potable water but as their distribution system completely sucks, that's not what the customers get...
But as you have a well, you get the best water, ground water and have control of the whole process till your tap...
