TEMPORAL DYNAMICS, ANTIMICROBIAL RESISTANCE AND PHYLOGENETIC RELATIONSHIPS OF BACTERIAL TAXA IN IRRIGATION WATER SOURCES AND RELEVANCE TO FOOD SAFETY
As climate change continues to stress freshwater resources, we have a pressing need to identify alternative (nontraditional) sources of microbially safe water for irrigation of fresh produce. Unfortunately, open water sources are often contaminated with many known human pathogens such as E. coli, …

Effects Of Nutrient Overload And Environmental Conditions On Algal Bloom Formation: A Case Study Of Water Sources In Eastern Kentucky
… algal blooms (HABs) that release toxins into the water, potentially limiting the use of these ponds. A pilot study in summer 2018 observed a harmful algal bloom (HAB) occurring in one pond in Madison Country that roughly correlated with a rise in water sulfate levels with no detectable levels of …

A field-based study of alternative microbial indicator tests for drinking water quality in Northern Ghana
Safe drinking water is essential for human survival, yet it is unavailable to over 1 billion of the world's people living in poverty (World Bank, 2009). The current methods used to identify drinking water sources are inadequate, with almost 40 percent of "safe" sources containing unsafe levels of …
