Enhancement of biodegradation of methanol and tertiary butyl alcohol in groundwater systems
… the next experiment. This was combined with the addition of alternative electron acceptors, nitrate and sulfate. Variation of pH in non-amended and sulfate-dosed (100 mg/L) microcosms did not enhance the biodegradation of either alcohol. Nitrate addition inhibited both methanol and TBA …

Prevalence, persistence and consequences of microorganisms within oil field environments and mitigation strategies
… can be mitigated by other microorganisms through nitrate addition to oil field systems.

Occoquan Reservoir and Watershed: A Water Quality Assessment 1973–2019
… and address eutrophication issues, including nitrate addition to hypolimnetic waters and installation of a hypolimnetic oxygenation system. The goal of this study is to assess how current management strategies implemented in the Occoquan Reservoir have affected the water quality from 1973 to …

Simultaneous determination of nitrous oxide and ammonia for measurement of in-situ fluxes from natural ecosystems by gas chromatography with headspace autosampler and electron capture detection
… of three bioremediation strategies: air purging, nitrate addition and full fertilizer addition. Compared to values reported in uncontaminated marshes N2O fluxes were lower by a factor of 7, and NH3 fluxes were slightly higher. This suggests that the petroleum had an inhibitory affect on …

Denitrification and greenhouse gas emissions from cultivated and wetland alluvial soils
… denitrification rates of restored wetlands. Nitrate addition to forested wetlands led to a 48% increase in N2O emissions. Forested wetlands exhibited net CH4 sink of 438-1050 g CH4 ha-1 y-1. CO2 emission decreased as WFPS increased from 40 to100% in forested wetlands. Low-elevation clay soils …

Computational Investigations at the Gas-Surface Interface: Organic Surface Oxidation and Hydrolysis of Chemical Warfare Agents and Simulants
… of ozone with C60-fullerene and the products of nitrate addition to a vinyl-terminated self-assembled monolayer. In the first system, we followed a reaction pathway beginning with primary ozonide formation through the formation of stable products. Theoretical vibrational spectra were used to …

Carbon and nitrogen removal in a granular bed baffled reactor
… with high nutrient levels could cause additional problems as anaerobic units are usually designed for the removal of organic matter. In addition, nitrate inhibition to methanogenesis in anaerobic environment could cause further problems during treatment. Therefore, a type of high rate …
