As Michael Deed said,

iron ist the most probable reason for your combined mud/taste problem. If you cannot clean the well -certainly the best solution- you may help yourselves by letting run the water through several recipients, thus aerating the water and provoke an oxygen-triggered chemical reaction & sedimentation of the mud in the water. Thereafter, you can / should filter the water trough commercial / industrial filters like the twin big blue or the filters distributed by airjuice corp. (Australia); there are many standardized solutions appropriate for ± 100 consumers. The filters are easier to handle, than sand filters and might prove to be more econmic on the mid and long term.
