are found outside the 50 foot radius from the aid, adjust the scale to fit the
site (ie. 1" = 50'). The distance from the aid to the last battery found will
be considered one (1) SITE RADIUS. The search for batteries should be extended
outward for one additional SITE RADIUS. For example, if the last battery found
is 40' from the aid, the search pattern should be out to a minimal distance of
80' from the aid. Take up to four (4) photos of each site.
Using the site plan drawing determine the area which represents the greatest
concentration of batteries. From the center of the area with the greatest
number of batteries you will take soil sample #1. Soil sample #2 will be taken
out at 1 SITE RADIUS within three feet of the position of the outermost
battery. Soil sample #3 should be taken out at SITE RADIUS 2. Soil sample #3
will be used as a background sample.
