Environmental Fate Of Sulfur In Sulphur Creek, Valles Caldera, Nm: Implications For Metal Transport And Water Quality, Daniel Lavery
Environmental Fate Of Sulfur In Sulphur Creek, Valles Caldera, Nm: Implications For Metal Transport And Water Quality, Daniel Lavery
Earth and Planetary Sciences ETDs
The 1.2 Ma Valles Caldera in north-central New Mexico hosts a young igneous volcanic hydrothermal system after the model proposed in Goff and Janik (2000). The Sulphur Springs area within Valles Caldera is an acid-sulfate area typical of this model, discharging acidic waters (pH 1.5-3) formed by oxidation of magmatic H2S at the surface. We report on samples obtained from springs and streams collected between October 2021 and May 2023 in the Sulphur Creek and Alamo watersheds. Sulphur Creek receives input from Sulphur Springs and exhibits low pH (2-4) and high concentrations of Al (≤110 mg/L), Fe (≤60 …
Water Quality Assessment In The Santa Fe River: Tracking Pollution Sources Via Quantitative Polymerase Chain Reaction Analysis, Hayley Aurora Hajic

Microbial contamination affects many water bodies in the United States and pathogens associated with contamination pose a threat to human health. While the nation’s lakes, streams and rivers have been monitored for decades, many still do not meet the requirements of the 1972 Clean Water Act. Due to the number of pathogens that occur in water bodies, it is not feasible to directly monitor all of them. Instead of testing for a plethora of pathogens, it is standard practice for water divisions to monitor fecal indicator bacteria (FIB) as a proxy to determine water quality. There are significant flaws, however, …
Water Quality And Public Health Monitoring Of Surface Waters In The Kura-Araks River Basin Of Armenia, Azerbaijan, And Georgia, Amy Ewing
Water Resources Professional Project Reports
The Kura-Araks (sometimes spelled Aras) River Basin is an international river basin located in the South Caucasus with five separate countries contributing area to the watershed. These countries are Turkey, Iran, Armenia, Georgia, and Azerbaijan. Surface water from the Kura and Araks Rivers is used for a variety of uses, including municipal, agricultural, industrial, and mining, and the waste products from each of these uses are discharged back into the rivers. Many of the resulting contaminants pose significant risks to human health, including exposure to organic pollution derived from municipal use, organochlorine pesticides and high nitrate from agriculture, chemical contamination …
