If you have a well, you should have a whole house filter with at least a
basic sediment filter cartridge in it. Most wells will pickup some sand
and crud at times that will clog faucet aerators and the like which the
whole hose filter with it's much larger surface area will handle much
better. The whole house cartridges are easier to change than chasing and
cleaning aerators and filters at individual fixtures too.

If you have a dirty well, I agree the whole house filter may pay off. But
it's just one more thing to change and leak. When our pump failed I put in
a filter but I'm thinking of bypassing it.

As for drought and water tables, yes shifts in the water table can cause
changes in the amount of crud a well picks up, as can nearby
construction activity.

It depends on how deep your well is. a 200' well usually gets the water
from many miles away. "They" determined our water comes from about 40
miles away. "Nearby" construction doesn't make any difference except that
new homes mean more wells and that can cause some problems caused by drawing
too much water out of the aquifer.
