Everybody on a well should have a cartridge filter. Preferably, a 4" x 10", or better a 4" x 20".
Could be normal activity in the ground stirring stuff up.
Could be a bad tank, bad pump (possibly the starting switch), bad check valves allowing the water to run back to the well.
Could be a hole in the drop pipe.
Water filters that don't backwash properly can start to puke stuff back into the water.
I can walk you through trouble shooting some of this stuff.
