Assessing the vulnerability of groundwater sources to fecal contamination
The Honolulu Board of Water Supply (HBWS) selectively chlorinates half of its groundwater supply to provide drinking water that meets the Total Coliform Rule. The objective of this study was to determine whether the groundwater sources used by HBWS are vulnerable to contamination with fecal matter and would require routine disinfection. Larger volumes (1,000 mL) of samples from groundwater and ...
متن کاملGroundwater Contamination
INTRODUCTION In the southern United States, chemicals are an integral part of the management of bare-root nurseries. The rationale for using chemicals is based on economics as they can reduce hand labor, improve the use of valuable seed, and increase seedling performance. The cost of all chemicals associated with loblolly pine seedling production averages less than 0.2 cent per seedling. The co...
متن کاملComparison of seven protocols to identify fecal contamination sources using Escherichia coli.
Microbial source tracking (MST) uses various approaches to classify fecal-indicator microorganisms to source hosts. Reproducibility, accuracy, and robustness of seven phenotypic and genotypic MST protocols were evaluated by use of Escherichia coli from an eight-host library of known-source isolates and a separate, blinded challenge library. In reproducibility tests, measuring each protocol's ab...
متن کاملUsing Bacterial Source Tracking and Other Innovative Techniques to Identify Sources of Fecal Contamination in Stormwater
Stormwater runoff can transport a variety of pollutants including heavy metals, excess nutrients, sediments, trash, etc. Several studies dating back to the 1970s have shown that a number of human pathogens are often present in stormwater and can lead to serious health risks. The resulting health and economic impacts can be significant since the presence of elevated concentrations of microorgani...
متن کاملManaging Groundwater Radioactive Contamination at the Daiichi Nuclear Plant
The Great East Japan Earthquake and tsunami of March 2011 severely damaged three reactors at the Fukushima Daiichi nuclear power station, leading to a major release of radiation into the environment. Groundwater flow through these crippled reactors continues to be one of the main causes of contamination and associated transport of radionuclides into the Pacific Ocean. In this context, a number ...
