I suspect that the crud at the bottom of your well and on the sides is
causing your coloured water. But after all this, I'm wondering if it
wouldn't just be better, and cheaper in the long run, to drill a new
well. Not a dug well with concrete rings, but a proper drilled well
with 8-inch steel casing. Drilled wells are inherently safer from
contamination by surface runoff. Shallow wells with the concrete
rings are an ongoing pain because stuff is always getting into them,
and they can be difficult to clean. Almost impossible, in your case.

See if any of the neighbours have drilled wells and what their water
quality is. You may just be throwing good money after bad by trying
to fix your shallow well. Again, the local health inspectors may be
able to give you valuable local information on local wells and the
groundwater quality.

Good luck.

I agree somewhat with a new well when compared to the one there now. But
there shouldn't be an assumption that with a new well there would be no
need for water treatment equipment. You (generally) may not need some of
what you have, or it might be too small and you'd need larger or
different equipment.
