ued to increase with time even at the later sampling
points and was consistently higher for undisturbed sites
than for campsites. A decline in AWCD from site 7
samples between 192 and 240 h was the result of a color
change in the control well between 192 and 240 h.
Analyses of microbial activity were done on OD readings
at 192 h to maximize microbial population growth and
before interference from external sources affected
