I have a new well, constructed in October, the third one we had to drill for our newly contructed home. We live in southwestern Virginia, where we are approaching drought conditions. The first well dried up quickly, after only two weeks of household use. The second well was a dud, barely putting out any water at all. The third well, drilled with an air drill, is 500 feet deep, and was putting out only 1-1.5 gallons per minute at the time it was drilled. The static level rose to within 70 feet of the top, and we have had plenty of water thanks to storage. The water, however, has not cleared up. The sediment filters I have installed between the well and the storage tank are still allowing really fine sediment, about the consistency of flour, into the house. I have tried acitvated carbon filters with low micron ratings, 5 then 1 respectively, with some success. But the problem is not solved. The well driller says that he, knowing he was coming into a dry area, instructed his employees to use a minimal amount of casing to ensure that no inflow was cut off. I am hesitant to mess with the well. 3 weeks with no water was enough, and I simply cannot afford to drill another well if we ruin this one. I would like to handle the sediment problem via filtration, but fear that conventional backwashing and/or reverse osmosis systems still won't take out the smallest stuff. I have heard that I may have my filters in the wrong place, that I may need to place them between the storage tank and the faucet. I plan to try that this weekend. Any thoughts, suggestions, or ideas would be greatly appreciated.
