There may be one or two water prob-lems in Maryland and Delaware that Ron Edwards and his staff haven't seen yet, but it's only a matter of time. "We have very diverse water in this area," says Edwards, 66, founder and CEO of Hague Quality Water of Maryland, based in Annapolis, MD. "We have as much as 35 parts per million of iron; we have sulfur, low pH, arsenic, radium. We have a lot of fun solving a lot of different problems. We have among the highest nitrates and chromium rates in the nation."
