Abstract

Human waste disposal is a health concern in many backcountry areas. This study measured Clostridium perfringens in beach sediments of Prince William Sound, Alaska, to detect fecal contamination resulting from intertidal disposal. Analysis involved holding times that exceeded eight hours. In repeatedly sampled stored sediments, C. perfringens did not decay for 101 days, indicating its reliability for detecting fecal contamination when stored. Fecal contamination was not detected in sediments while campers practiced intertidal disposal. Concentrations of C. perfringens at beach campsites did not correlate with use. The lack of detectable fecal contamination in affected beach sediments suggests that intertidal disposal of wastes may be a safe method for up to 13 campers in a group.
