R <br /> Well Ivo. 3, the northerly well , had a standing w' er level <br /> of -39. 82' below the casing top. Six gallons were bailed <br /> from the well (about 6.6 gals . were calculated to equal five <br /> times the water column in the well ) . The well .;as almost <br /> bailed dry at this point. The water recovered was slightly <br /> muddy at first clearing towards the end. Samples were <br /> collected as described above. Sampling %..as completed at 2: 20 <br /> P11. After a 10 minute wait, the water level was measured <br /> again and it was found at -39. 50' , .02' higher than the <br /> first measurement. <br /> WATER SURFACE AND SLOPE <br /> i-ir.
