A friend of mine owns a house just up the road from Los Brazos on the Sabaneta - Moca highway and drinks well water.....his well is about 220 feet down and hasn't been sick in over 15yrs.....I guess it depends on where you are.....I have drank his water and didn't get sick, but in town don't drink tap water, only bottled water.....
Oh just a funny story..... Watched a guy on that sells bottled water filling his jugs up on the street in Cabarete from a hose and put the seal on the top and taped it on....
The big trucks that sell water, sell that water for cooking not for drinking......A lot of people won't use tap water for cooking, so they buy water from the truck strictly for cooking, and use bottled water for drinking, tap water for washing clothes and bathing....
