PROCEDURES AND SAMPLING LOCATIONS

B-I

PROCEDURES AND SAMPLING LOCATIONS

All sampling procedures, analytical methods, and data manipulations remain

the same as described in earlier reports. However, this reporting period

covers the months July through October, 1969, rather than the calendar quar-

ter. Subsequent reports will each cover a three month interval, beginning

with the period November, 1969, through January, 1970. Results for each

calendar year will be summarized.

During this reporting period NFS-Erwin relocated the security fence around

the plant facilities and thus necessitated a change in some of the IMP

sampling locations. The "security" and "restricted" areas now enclosed

by fence are much larger than before. The relative positions of the sampling

locations on the site perimeter remain the same, but their actual distances

from facility buildings have increased. All of Banner Spring Creek and a

section of Martin's Creek above and below the entrance of Banner Spring Creek

are now within the boundary of the restricted area. Figure 3 shows the lo-

cation of both the new and old fences and the present approximate positions

of the site perimeter sampling locations.

Because of the small number of water and water sediment samples (quarterly

sampling intervals), all 1969 results for these samples are reported.

Sampling locations, types of samples, and figures of the NFS (E) area com-

prise the remainder of this section.
