TABLE 7-9 • <br />(Continued) <br />(e) Transmissivity value for YLb is suspect because annular space between the <br />boring end casing is flowing at the ground surface (well seal failure) and the <br />value is 700 times greeter then the overburden trensmissivities measured et <br />YOY9, YOV28, end YOV30. <br />(f) Transmissivity value for TLOV3 is suspect because annular spate between the <br />boring end teeing is flowing at the ground surf ate (well seal failure) end the <br />trensmissivity is higher then any regional values determined for the <br />overburden and 1060 times greater than the overburden transmissivi[y values <br />measured et TOV9, YOV28, end TOV30. <br />(g) Transmissivity veLue for YLOV4 is suspect because annular space between the <br />boring and casing is flowing et the ground surface (well seal failure) end the <br />trensmissivity is 529 times greeter then the overburden trensmissivity values <br />measured et YOV9, YOV28, and YOV30. <br />(h) Transmissivity value for YOV7 is suspect because the boring was overdrilled 90 <br />feet with only a 7-foot seal to prevent leakage, the well is in hydraulic <br />communication with the lower coal units (well seal failure) as evidenced by <br />the drewdown in Well YW2 while pumping YOV1, and the trensmissivity value is <br />2.6 times greeter than the highest regional overburden value and 2200 times <br />greeter than YOV9, YOV2B, and YOY30. <br />(i) Transmissivity value for YW2 is suspect because annular space between the <br />boring and casing flows at the ground surface (well seal failure) certain <br />times of the year, the well showed water level drawdowns while pumping YOV1, <br />the well was overdrilled 96.5 feet, and the trensmissivity value is 2.9 to 85 • <br />times greater than regional values for the Wedge coal and 7077 times greater <br />than values measured for the Wedge coal at Yoast Wells YW23, YW28, YW24, and <br />YY30. <br />(j) Hydraulic conductivity values could not be determined because of well seal <br />failures et these wells <br />(k) Hydraulic conductivity values could not be determined because of incomplete <br />well completion information <br />References: Oldeker, P., Well Testing-Yoest end Seneca II-W Projects: Consultant report <br />prepared for PYCC, August 5, 7993. <br />Oldaker, P., Yoest-Hydrology/Hydrogeology Study Final Report: Consultant <br />report prepared for PWCC, January 9, 7991 <br />• <br />32 Revised 03/07/95 <br />
