Appendix 2. Water-level
measurements for selected wells on Pahute Mesa and vicinity, Nevada
Test Site, 1963-98
Method used to determine depth to
water: L, interpreted from geophysical log; R, reported, method
not known; S, calibrated steel-tape measurement; T, calibrated
electric tape; V, calibrated electric cable (wire line or iron horse).
Quality-assurance flag: A, anomalous value; AT, water level
does not agree with second access tube in same open interval; C,
affected by well construction, queried where uncertain; D, dry
hole; H or L, static water level in well is elevated above (H) or
depressed below (L) regional ground-water level; R, well pumping or
recently pumped; N, water level affected by nuclear test; X, water
level corrected for borehole deviation; --, no flag applied
Water above bottom of open interval: length of water column in
well from top of water to bottom of open interval listed in table
1.
