Surface discharges of anthropogenic nutrients historically have been the focus of Florida’s waterquality regulations. Groundwater contributions to eutrophication of Florida’s surface waters are a more recent focus. Florida’s naturally oligotrophic springs, streams, and lakes are experiencing significant anthropogenic nutrient contamination resulting from groundwater discharges with elevated nit...

Water (brine) co-produced with oil in the Williston Basin is some of the most saline in the nation. The Prairie Pothole Region (PPR), characterized by glacial sediments and numerous wetlands, covers the northern and eastern portion of the Williston Basin. Sheridan County, Montana, lies within the PPR and has a documented history of brine contamination. Surface water and shallow groundwater in t...

The standard index of microbial air contamination (IMA) for the measurement of microbial air contamination in environments at risk is described. The method quantifies the microbial flow directly related to the contamination of surfaces coming from microbes that reach critical points by falling on to them. The index of microbial air contamination is based on the count of the microbial fallout on...

Acid-base data for oxide minerals are fundamental building blocks for adsorption models. Although the influence of impurities is often discussed in a qualitative way, a quantitative analysis is largely missing. A notable exception is the discussion of the possible effect of surface impurities on the results of mass titrations. In the present contribution potential contaminations are discussed i...

Introduction: Neutron contamination is very harmful for the patients receiving radiation therapy due to the high relative biological effect of neutrons. Medical linear accelerators head are made up of materials with high atomic numbers, and High-energy photons interaction with heavy materials can produce neutron contamination. In this study, neutron equivalent dose, neutron spe...
