Giardiasis: a return of waterborne disease
Complacency about safe water supply has turned to concern over possible chemical contamination and waterborne disease, giardiasis, caused by a protozoan. A case study of an outbreak of giardiasis in Pennsylvania raises questions about water treatment strategies, which must necessarily vary because of differences in public water systems. While giardiasis is an unpleasant and uncomfortable disease, it is not as serious as typhoid, dysentery, and other diseases. The costs of analyzing water systems to detect and eliminate the risk of contamination may exceed the costs of the disease itself. Americans have grown used to safe drinking water, however, and may conclude that the benefits are worth the cost. 2 figures, 1 table.
