Most driller , pump installers and plumbers aren't water quality people. Have the water tested by a certified testing laboratory. Then take the results to a reputable water conditioning company and have them mak recommendations (in writing).
To condition bad well water with water conditioning is usually a band-aid for the real problem. If possible it's always best to rectify the situation at the source. . . the well! If it's iron in the water it's usually treatable. . . if it's actually mud (clay) in the water, it could be a leak at the casing seal. A qualified driller with a downhole camera may be able to determine a leak at the casing seal. This is assuming you have a rock well and not a sand well. Since you are in centeral North Carolina I am assuming it's a rock well.
