A sinkhole, now about 2 feet deep and approx. 4 feet wide by 5 feet
long, has formed within 5 feet from my deep well equipped with a
submersible pump over 100 feet down. My water supply has not been
affected so far and the pump is doing just fine, judging from the
strong water pressure in the house. Is this just coincidence, or has
the pump got something to do with it? We had a long drought here in
Northern VA followed by torrential rains about 2 weeks ago. Should I
be worried about this, and what can be done about it? Should I wait
until the pump stops working? Thanks for any help.

Actual timing is probably not totally coincidental but areas in VA are
notoriously susceptible to sinkholes from various reasons. Limestone
subsidence is relatively common, but depending on where you actually are
in VA it could even be an old mine shaft.
I'd suggest contacting local authorities and have it investigated -- it
could be small inconvenience or it could be the forerunner of a major
collapse. Only determining local geology and cause can tell.

Thanks for your valuable feedback. Do you happen to know what specific
local government agency or department needs to be contacted? Thanks
again.

I'd start w/ County Engineer (assuming that having a well implies you're
not in a City)...
