Association of runoff risk with private well contamination in a fractured dolostone aquifer. [PDF]

J Environ Qual
Abstract In the United States, private well owners are responsible for monitoring and maintaining their drinking water but have little control over neighboring contamination sources and limited information about daily water quality. Potential for rapid contamination in karst settings exacerbates the challenge.

Microbiological Quality and Analysis of Escherichia coli Resistance to Antibiotics in Beaches: Evaluating Anthropic Influence in Surface Waters in Brazil. [PDF]

Water Environ Res
Anthropic activities and untreated wastewater promote the dissemination of antibiotic‐resistant E. coli (83.3% of isolates) in coastal waters, increasing environmental contamination and public health risks. ABSTRACT Antimicrobial resistance is a problem for public health.

Comparison of Fecal Coliform Agar and Violet Red Bile Lactose Agar for Fecal Coliform Enumeration in Foods [PDF]

Applied and Environmental Microbiology, 2002
ABSTRACT A 24-h direct plating method for fecal coliform enumeration with a resuscitation step (preincubation for 2 h at 37 ± 1°C and transfer to 44 ± 1°C for 22 h) using fecal coliform agar (FCA) was compared with the 24-h standardized violet red bile lactose agar (VRBL) method.

Validity of fecal coliforms, total coliforms, and fecal streptococci as indicators of viruses in chlorinated primary sewage effluents [PDF]

Applied and Environmental Microbiology, 1978
Quantities of combined chlorine that usually destroyed more than 99.999% of the indigenous fecal coliforms, total coliforms, and fecal streptococci in primary sewage effluents destroyed only 85 to 99% of the indigenous viruses present. Viruses were recovered from five of eight chlorinated primary effluents from which fecal coliforms were not recovered ...

Removal of fecal coliforms from sewage treatment plant tailwater through AMF-Canna indica induced bioretention cells

Ecological Indicators, 2023
Fecal coliform in the tailwater from sewage treatment needs to be deeply removed by chlorine disinfection, but ensuing disinfection by-products (DBPs) bring severe environmental and sanitary risks.

Microtechnique for isolating fecal coliforms from soil [PDF]

Applied and Environmental Microbiology, 1983
A most-probable-number microtitration technique for isolating fecal coliforms from soil was developed. A correlation coefficient of 0.86, with a 95% confidence interval of 0.76 less than zeta less than 0.92, was obtained when this technique was compared with the standard elevated-temperature fecal coliform most-probable-number procedure.

Use of microbial fecal indicator monitoring and fecal source tracking as a park management tool in Rocky Mountain National Park

Environmental Challenges, 2022
Visitation to national parks in the United States increased by an estimated 9,304,786 visitors from 2018 to 2019. This increased visitation has resulted in negative impacts to protected natural resources.
