Bacterial Contamination of Water Resources on Moen, Truk Islands, Federated State of Micronesia

摘要

Shallow wells and individual rainwater catchment systems meet the water requirements of many Micronesians. The quality of this water is a matter of public health interest because this region suffers from a high incidence of gastrointestinal disorders and water-related diseases. Poor sanitary conditions and particularly inappropriate excreta disposal practices pose a significant threat to shallow groundwater quality. Groundwater is usually used for nondrinking purposes; however, when alternative water sources are unavailable groundwater may be consumed. Rainwater catchment systems are the preferred source of drinking water. Catchment systems are often poorly maintained and storage capacity inadequate to last through even brief dry periods. The relationship between ambient sanitary conditions and shallow groundwater quality was examined on the island of Moen, Truk, Federated States of Micronesia. Sanitary conditions in the areas surrounding each site were evaluated. Special attention was paid to the proximity of latrines and to the presence of animals and standing water.
