* Value for well is computed using less than the full period of record because
of a change in well hydraulics, or nearby non-climatic
hydrologic stress.
^ Below normal conditions for well SO-2 are due to nearby pumping.
+ Well MR-1364 was affected by the Pymatuning Earthquake on Sept. 25, 1998.
Record adjusted to compute current conditions shown on
map.
Note: Water levels from well MG-225 are being collected but not reported in
this monthly summary, because they are not comparable to
historical levels due to changes in ground-water pumping.
