Communities at Risk - Protecting Family Drinking Water in Rural Alaska

People living without piped water and sewer can be at increased risk  for diseases transmitted by the fecal-oral route. One Alaskan   community that relies on hauled water and sewage was studied to   determine the pathways of fecal contamination of drinking water and   the human environment so that barriers can be established to protect   human health. Samples were tested for the fecal indicators  Escherichia coli and Enterococcus. Several samples were tested for   the pathogens Giardia lamblia and Cryptosporidium parvum and source   tracking methods were employed. Surface water flow transported   bacteria within the community during spring thaw and human fecal   contamination was detected in town, but flow from the dump did not   appear to contribute to contamination in town.    Within the home, fecal bacteria were found on water dippers, kitchen   counters and floors, and in hand-washing basins. Giardia was found   at the dump, but not in water from the river adjacent to the   community. Exposure to fecal contamination could be reduced by   cleaning up after dogs, carefully disposing of wastewater, and by   protecting stored drinking water.    (microbial source tracking); (MST); (bacterial source tracking);   (BST); (Giardia lamblia); (Enterococcus); (E. coli);   (Cryptosporidium parvum)
