NOTES:
1. All locations and dimensions of site and near vicinity features are approximate only.
2. All wells were surveyed on November 3, 1992 and June 21, 1993 for elevations from a-
Na"ona' Geodedic Vertical Datum benchmark (1929).
3 Wa•e, tab'e elevations are based on measurements taken on September 27, 1993.
4. G•o--d wale, contours are ir:erpola:ed between data points and inferred in other areas.
G•a.,^d waver contours are representative of conditions measured on the dates indicated.
Leve's may vary overtime due to seasonal changes or other factors. Water table e!evation data
at MW -14D ^as rot been included in mapping these contours.
5. Grouted waver contours and flow directions shown assume homogeneous and isotropic aquifer
co ,c , o^s and horizontal flow. AC'ual subsurface conditions may vary from those shown.
6. Laboratory resu!:s are from September 27 and 28, 1993 sampling events.
7. Figu•e derived from'Monitonng We" Location Plan', prepared by Golden Land Survey, Inc.,
