Microbial Source Tracking in the Manasquan River Estuary: Research Project Summary

Multiple Antibiotic Resistance (MAR) analysis, one of several new tests developed within the past decade, was used in an attempt to identify the sources of fecal pollution in the Manasquan River estuary. The estuary is vital for recreational activities and as a shellfish resource. The test identifies fecal-derived, human- and animalspecific Escherichia coli (E. coli) bacteria through host-influenced differences in antibiotic resistance. The estuary contains multiple sources of fecal pollution. At many sites there appears to be an abundance of inputs from wild animals. This is an ongoing study. The work to date is best viewed as a “pilot project,” providing a tool to begin to identify sources of E. coli in the estuary. Due to the current limitations of the MAR technology and the lack of unambiguous source apportionment at most sites, the best use of the data may be to rule out potential sources of pollution.

Survey of Surface Source Waters for Giardia And Cryptosporidium and Water Treatment Efficiency Evaluation: Research Project Summary
(Trenton, N.J. : Department of Environmental Protection, Division of Science and Research, 1995-08) Atherholt, Thomas B.; LeChevallier, Mark W.; Norton, William D.
Giardia and Cryptosporidium (shortened to "Crypto") parasites are among the leading identified causes of waterborne disease in the United States. Giardia cysts and Crypto oocysts have been identified in many surface waters throughout the country, but the concentrations in most of New Jersey's (NJ) surface waters, many of which are used as source waters for drinking water treatment plants, are unknown. To provide safe drinking water, treatment plants need to remove Giardia and Crypto from untreated water or reduce their concentrations to safe levels. Peak parasite levels, together with adverse water treatment factors, such as low water temperature, determine the maximum risk of human infection. However, parasite testing is not required by law and is not routinely performed by water treatment plants or regulatory personnel because the methods available are difficult, expensive, time-consuming, and have other drawbacks.
