Years ago we moved into an apartment complex, the water was horrible. My husband called to have it tested it wasn't that great. We ended up installing two different pre-filters and a reverse osmosis system under our kitchen sink just to make sure that we were drinking the best possible water we could without the germs. We talked to the manager in the office at the apartment complex. They told us that the water was generally good drinking condition. By contacting the local health department we started receiving through our email quarterly postings of the water condition. It was amazing how many times e-coli virus had been in the water and it did coincide with everyone getting sick almost at the same time that this was reported. We're thankful for our filter system stopping this for us.
