Creator:

Weisberg, Stephen B., Bednaršek, Nina, Feely, Richard A., Chan, Francis, Boehm, Alexandria B., Sutula, Martha, Ruesink, Jennifer L., Hales, Burke, Largier, John L., and Newton, Jan A.

Abstract:

This is PMEL Contribution 4396. Acidification has sparked discussion about whether regulatory agencies should place coastal waters on the Clean Water Act 303(d) impaired water bodies list. Here we describe scientific challenges in assessing impairment with existing data, exploring use of both pH and biological criteria. Application of pH criteria...

Enterococcus and Escherichia coli fecal source apportionment with microbial source tracking genetic markers - Is it feasible?

Creator:

Wang, Dan, Farnleitner, Andreas H., Field, Katharine G., Green, Hyatt C., Shanks, Orin C., and Boehm, Alexandria B.

Abstract:

Fecal pollution is measured in surface waters using culture-based measurements of enterococci and Escherichia coli bacteria. Source apportionment of these two fecal indicator bacteria is an urgent need for prioritizing remediation efforts and quantifying health risks associated with source-specific pathogens. There are a number of quantitative real-time PCR (QPCR) assays...
