mentioned above, and as evidenced by the water well some one-half mile away. These exploration holes were drilled. at a rapid penetration rate using compressed air for cuttings removal. If wet zones are encountered, the large volume and high pressure of the drilling air tends to dry limited inflow. Damp zones on the wall of the hole will catch the dry cuttings from the strata being penetrated below, forming a cake, so that the hole continues to be drilled dry. If the cuttings become damp and sticky or fractures are encountered so that the hole is not thoroughly cleaned, the driller must begin injecting some water with the compressed air to flush the. cuttings from the hole. That depth must not be considered a water table unless water begins exiting the hole prior to the driller beginning injection. It is therefore not possible to say with any certainty if, or where, any water actually comes into the hole, nor at what volume. If cuttings do become damp, it usually occurs at some point below the water-bearing zone, and has to do with drilling rates and down time. However, the cuttings, electric. logs of the hole, and depth at which the driller had to start injecting can be used to estimate a potential water-bearing zone's location. On the other hand, the water exiting the hole is almost entirely that which the driller injected, therefore, it is not possible to acquire any ground water quantity or quality data from this type of exploration drill hole. ' Along with the plugging diagram in Appendix A are notes showing where the driller began injecting water and the water level standing in each hole'when it was probed. These standing water levels should.not be thought of as the static water level. C. Each drill site and access routes to .each hole have been reclaimed. Pits were backfilled to cover the cuttings that were not returned to the holes. Cuttings outside the pits were mostly raked into the soil or were scattered thin. Rocks, dead brush, and trees, were scattered about the disturbed areas. Ali disturbed areas were scarified and seeded. Photos of the sites taken from similar view points .as the pre-disttubance photos are enclosed. D. Drill holes are marked on the ground~by 2"x2" wooden stakes with metal tags showing the hole IDs. A drill hole location map is attached as Appendix B. The hole locations are given in UTM {NAD 27) coordinates in the following table: Hole Number UTM~ 12 S East North WW-07-I S 668830 4278144 W W-07-16 668727 4278254 WW-07-17 668742 4278289 WW-07-18 668767 4278266 WW-07-19 ~ 668380 ~ 427$385 W W-07-20 668396 4278364 WW-07-21 66841.1 ~ 4278337 WW-07-22 668455. 4278358 WW-07-23 668440 .. 4278387 W W-07-24 668427. 4278414 W W-07-25 668513 4278441 WW-07-26 ~ 668477 4278445 W W-07-27 668455 4278443 W W-07-28 668459 4278420
