'Depths measured from ground surface during well installation and reported on the monitoring well construction logs
2Well depths measured by SynTerra, June 30 and July 1, 2015
3 Where total depth was not measured well screen elevations were estimated, based on the difference between TOC and ground surface elevations.
Monitoring well coordinate and elevation data for newly installed wells from surveys provided by McKim & Creed, completed 8/14/15. McKim and Creed also verified survey location at several existing locations.
* No boring logs available for "CHATH" piezometers, monitoring zone assigned based on depths and comparison to nearby sample locations with boring logs
