l' S urve-of :alec instruments and resistance reasurements of lines to retruments at earlous levels yielded no definitive results.

2)

Eesistance.casurements of leads to several motor operated valves were all h:gn and therefore yielded no definitive result.

3)

esistance =easurecents of leads to pump motors at 2'6" and below we
c all nero, indicating water level is above 2'6".

J. ;

Resistance reasurements of lines to power receptacles at approximately four :eet were all cero, indicating water is above four feet.

Future resistance reasurements of leads o additional ctor operated salves (below the electrical penetrations rnd above ~ 6") ca:-
