GENERAL NOTES
Photoionization detector (PI D) field headspace reading (in parts per million).

NO indicates that no organic vapors were detected.

Comments or observations regarding drilling/sampling made by driller or URSGWC's field personnel

1. Soil classifications are based on the Unified Soil Classification System (USCS) or recorded and include consistency/relative density (where standard blow count correlation is possible). moisture, and color.

2. Descriptions on these boring logs apply only to the specific boring locations at the time the borings were advanced. They are not warranted to be representative of subsurface conditions at other locations or for other times.
