We had Robert Gorovenko test our water in June 05.  At the time we had an iron permanganate system which we've since made into flower pots, because we couldn't find a garbage dump to put it in.   The thing wasn't working, we have high PH, high H2S, and high iron and we were getting high drinking it.  Robert recommended a chlorine injection system, and the Reverse Osmosis for drinking and cooking.  The old adage, you get what you pay for, is really true here.  We don't use rubber gloves any more for cleaning, our skin is not chapped anymore and our hair is softer.  There are no stains on the surface of the tub, taps, toilets etc, and they are not being destroyed like they were before.  We us far less soap, because it is much more efficiently used due to the water being softened.  Robert is very informative and helpful, and he gave us very good service.  We encourage everybody to have their water tested and get a good system for their health and home.  You won't be disappointed!
