AMENDMENTS TO:
FIELD PROCEDURE FP 5-1
MONITORING OF HOLLOW STEM AUGER DRILLING ACTIVITIES
The following are specific amendments to the referenced SOP. The amended portions
of the SOP are marked and correspond to the comments listed below.
1. MONITORING OF HOLLOW STEM AUGER AND CABLE TOOL DRILLING
ACTIVITIES.
2. This procedure applies to hollow stem auger and cable tool drilling activities
used to install monitoring wells and drilling activities to determine the type, thick-
ness and certain physical and chemical properties of the soil, water, and rock
strata which underlie the site.
3. 5.2 Cable tool drilling is a procedure which creates a borehole by advancing a
chisel-like bit and steel casing through the substrata. Cuttings and samples are
brought to the surface using a sand bailer. Cable tool drilling can create a
plumb borehole in both consolidated material (i.e., bedrock) and large diameter
unconsolidated material (i.e., large boulders). Samples from the borehole can
be collected from the sand bailer.
4. Amendment not implemented.
5. Amendment not implemented.
6. Use of drilling fluid and quantity used during drilling/reaming/augering.
