Recommendations for filtering large amount of intermittent sediment from well water
We drilled a well in May of this year to replace our spring. It goes 545 ft deep. They hit rock (limestone, sandstone) at 17 feet. The casing goes down 20 feet as does the bentonite grout. Shortly after the well was installed, after a very heavy downpour, we had a lot of red clay-like sediment in the water, which cleared after a couple of days. Then this week after a couple days of steady rain the water became extremely muddy (looked like apple cider). It has cleared , gotten muddy again , then is clearing again now after running a lot of water from the hydrant connected directly at the well head. We have been assured by the well driller, and the sanitation engineer at the Health Dept that it could not be due to surface water, but is due to a disturbance deep in the ground water. We know now that we need a whole house system to filter the sediment. What we are wanting is recommendations for the type and micron size of the filters. We were thinking that a series of filters , going from larger micron size to smaller would be a good idea, but what sizes? and how many? The sediment appears to be a fine clay-like material. Thanks for your help.
