Autor: Mark A. Borchardt, Burney A. Kieke, Susan K. Spencer, Elisabetta Lambertini, Tucker R. Burch, Frank J. Loge

Publikováno v: Journal of Water and Health, Vol 21, Iss 9, Pp 1209-1227 (2023)

By community intervention in 14 non-disinfecting municipal water systems, we quantified sporadic acute gastrointestinal illness (AGI) attributable to groundwater. Ultraviolet (UV) disinfection was installed on all supply wells of intervention communi

Autor: Sandra L. McLellan, Elizabeth P. Sauer, Steve R. Corsi, Melinda J. Bootsma, Alexandria B. Boehm, Susan K. Spencer, Mark A. Borchardt

Publikováno v: Elementa: Science of the Anthropocene, Vol 6, Iss 1 (2018)

Despite modern sewer system infrastructure, the release of sewage from deteriorating pipes and sewer overflows is a major water pollution problem in US cities, particularly in coastal watersheds that are highly developed with large human populations.

Publikováno v: Journal of environmental quality.

Antimicrobial resistance is a growing public health problem that requires an integrated approach among human, agricultural, and environmental sectors. However, few studies address all three components simultaneously. We investigated the occurrence of

Statewide Quantitative Microbial Risk Assessment for Waterborne Viruses, Bacteria, and Protozoa in Public Water Supply Wells in Minnesota

Autor: Tucker R. Burch, Joel P. Stokdyk, Nancy Rice, Anita C. Anderson, James F. Walsh, Susan K. Spencer, Aaron D. Firnstahl, Mark A. Borchardt

Publikováno v: Environmental sciencetechnology. 56(10)

Infection risk from waterborne pathogens can be estimated via quantitative microbial risk assessment (QMRA) and forms an important consideration in the management of public groundwater systems. However, few groundwater QMRAs use site-specific hazard

Publikováno v: Environmental Science & Technology. 54:3159-3168

In the United States, approximately 48 million people are served by private wells. Unlike public water systems, private well water quality is not monitored, and there are few studies on the extent and sources of contamination of private wells. We ext

Fate and seasonality of antimicrobial resistance genes during full-scale anaerobic digestion of cattle manure across seven livestock production facilities

Autor: Tucker R. Burch, Aaron D. Firnstahl, Susan K. Spencer, Rebecca A. Larson, Mark A. Borchardt

Publikováno v: Journal of environmental qualityREFERENCES. 51(3)

Anaerobic digestion has been suggested as an intervention to attenuate antibiotic resistance genes (ARGs) in livestock manure but supporting data have typically been collected at laboratory scale. Few studies have quantified ARG fate during full-scal

Publikováno v: Environmental Science & Technology. 53:3391-3398

Regulations for public water systems (PWS) in the U.S. consider Cryptosporidium a microbial contaminant of surface water supplies. Groundwater is assumed free of Cryptosporidium unless surface water is entering supply wells. We determined the inciden
