Opportunistic Pathogens and the Brain-eating Amoeba, Naegleria fowleri in Reclaimed Water, Municipal Drinking Water, and Private Well Water
… reclaimed water systems, aging water mains, and private well systems. Phase one examined the role of biological treatment to remove organic carbon and disinfectant type on the occurrence of OPs during distribution of reclaimed water. Laboratory-scale simulated reclaimed water distribution systems …

Quantifying Potential Sources of Microbial Contamination in Household Drinking Water Samples
In Virginia, over one million households rely on private water supplies (e.g. well, spring, cistern). Previous literature acknowledges bacterial contamination in private water supplies as a significant public health concern in the United States. The present study tested private wells and springs in …

Associations between Fecal Indicator Bacteria Prevalence and Demographic Data in Private Water Supplies in Virginia
Over 1.7 million Virginians rely on private water systems to supply household water. The heaviest reliance on these systems occurs in rural areas, which are often underserved in terms of financial resources and access to environmental health education. As the Safe Drinking Water Act (SDWA) does not …
