I. Individual.well data were NA. Total gallons estimated from oil pumped. 2. Individual well measurement was NA due to equipment failure. Total gallons estimated from oil pumped. 3. Thickness of oil not measureable due to heavy rain. 4. Oil sheen in well;thickness not measureable. S. Product too viscous to vacuum. 6. Oil sheen in well;oleophilic sock in use. 7. SPO too thick to obtain accurate thickness measurement. 8. Oleophilic socks placed in all SPO wells during the fourth quarter of 2006.Trial SPO removal method. 9_ Thickness of SPO is approximate and was calculated by collecting a second depth-to-SPO measurement after extraction, I 10.Not accessible due to alleyway reconstruction project. 11.Beginning August 15,2007,SPO/water mixture thickness recorded as well depth minus depth to SPO. Entire well column was evaculated during extraction. 12.Total estimated minimum thickness of SPO/water mixture removed in feet since April 1997. 13.Total estimated minimum gallons of SPOAvater mixture removed since April 1997;converted to gallons using 1 foot of depth equals 0.653 gallons of crude oil for 4inch-diameter wells.
