Journal ArticleDOI

Microbial partitioning to settleable particles in stormwater.

TL;DR: Estimates of the fraction of organisms associated with settleable particles in stormwater should be valuable in surface water quality modeling efforts, many of which currently assume that all microbes exist as free (unattached) organisms.
Journal ArticleDOI

Outbreak of viral gastroenteritis due to a contaminated well. International consequences.

TL;DR: The investigation documented SRSVs in a vehicle epidemiologically linked to a gastroenteritis outbreak, demonstrating the power of molecular detection and identification and underscore the importance of fundamental public health practices such as restaurant inspection, assurance of a safe water supply, and disease surveillance.
Journal ArticleDOI

Intra-storm variability in microbial partitioning and microbial loading rates

TL;DR: Higher concentrations of both settleable particles and microbes entering the water column soon after the onset of a storm led to higher loading rates of settleable microbes in the storm's earliest stages, a trend that could have important implications for the design of stormwater management structures (e.g., detention basins).
Journal ArticleDOI

Concentration and Detection of Cryptosporidium Oocysts in Surface Water Samples by Method 1622 Using Ultrafiltration and Capsule Filtration

TL;DR: The capsule filter system currently recommended for method 1622 was compared to a hollow-fiber ultrafilter system for primary concentration of C. parvum oocysts and the recovery rates were significantly lower and more variable than those from reagent grade water.
Journal ArticleDOI

Statistical Evaluation of Factors Affecting Indicator Bacteria in Urban Storm-Water Runoff

TL;DR: In this paper, an urban watershed in Raleigh, North Carolina, was monitored for indicator bacteria during 20 rain events and the results showed elevated levels of E. coli, enterococci, and fecal coliform.
