Nitrogen sources and cycling in natural waters by Patrick L Brezonik( Book )

3 editions published in 1973 in English and held by 226 WorldCat member libraries worldwide

Sources of nitrogen were reviewed to determine their significance in lacustrine budgets. Nutrients in rainfall were found significant although their variability obviates precise conclusions. Using literature values for nutrient export from various land uses, nutrient budgets were calculated for 55 Florida lakes. Critical N and P loading rates (above which eutrophication is likely) were estimated from the calculated budgets and lake trophic conditions. Algal fixation in two eutrophic Florida lakes was studied in detail; the total amount of N fixed and factors affecting the occurrence of fixation were evaluated. A survey of fixation in 55 Florida lakes showed significant fixation only in eutrophic lakes. Bacterial fixation in the anoxic hypolimnion of a small lake contributed substantial nitrogen to the lake, and N fixing activity was found in both estuarine and lacustrine sediments. The acetylene reduction assay for N fixation was evaluated; short incubations were found essential. Reduction was light-dependent and N2 acted as a competitive inhibitor. A preliminary experiment suggested that lacustrine sediments act as ammonia buffers; estuarine sediment sorbed ammonia strongly with little tendency to release ammonia to the water. Interferences from high organic color were evaluated for automated inorganic N and P analytical methods. Various amino acids were also shown to interfere with the indophenol ammonia procedure

Ground water pollution in Arizona, California, Nevada & Utah by United States( Book )

4 editions published between 1971 and 1972 in English and held by 145 WorldCat member libraries worldwide

An investigation to determine the ground water pollution problems which exist in the states of Arizona, California, Nevada, and Utah was conducted. Data were obtained through an extensive review of the literature and through interviews with engineers, scientists, and governmental officials concerned with water pollution in the four states of the project area. Mineralization of ground water is the most prevalent factor in the degradation of ground water quality in the project area. Large quantities of ground water in each of the four states are undesirable for many uses because of excessive mineralization. Much of the mineralization of ground water is a result of natural processes. A listing of conditions causing ground water pollution in the project area is included

Water pollution aspects of street surface contaminants by James D Sartor( Book )

3 editions published in 1972 in English and held by 134 WorldCat member libraries worldwide

Material which commonly reside on street surfaces have been found to contribute substantially to urban polution when washed into receiving waters by storm runoff. In fact, runoff from street surfaces is similar in many respects to sanitary sewage. Calculations based on a hypothetical but typical U.S. city indicated that the runoff from the first hour of a moderate-to-heavy storm would contribute considerably more pollutional load than would the same city's sanitary sewage during the same period of time. This study provides a basis for evaluating the significance of this source of water pollution relative to other pollution sources and provides information for communities having a broad range of sizes, geographical locales, and public works pracices. Information was developed for major land-use areas within the cities (such as residential, commercial and industrial). Runoff was analyzed for the following pollutants: BOD, COD, total and volatile solids, Kjeldahl nitrogen, nitrates, phosphates, and a range of pesticides and heavy metals. This report was submitted in fulfillment of Project No. 11034 FUJ, Contract No. 14-12-921 under the sponsorship of the Water Quality Office, Environmental Protection Agency
The carbon dioxide system and eutrophication by Stephen D Morton( Book )

4 editions published in 1971 in English and held by 132 WorldCat member libraries worldwide

To determine the feasibility of eutrophication control by controlling carbon, three major areas were studied: the steady state, in which the growth rates of algae at various constant, maintained dissolved carbon dioxide concentrations were determined; the non-equilibrium, where natural atmospheric replenishment was the sole carbon source; and algal growth with inorganic bicarbonate as the sole carbon source. In studying growth rates of Chlorella, Microcystis, and Anabaena with respect to carbon availability, it was found that algae can utilize dissolved concentrations of carbon dioxide much lower than those from atmospheric equilibria

Study of reutilization of wastewater recycled through groundwater by Doyle F Boen( Book )

4 editions published between 1971 and 1972 in English and held by 127 WorldCat member libraries worldwide

A project to demonstrate the feasibility and safety of recycling water under operating conditions was performed in the Hemet-San Jacinto Valley of the State of California. Since the Valley is a closed basin, and is dependent in part upon imported water, it was felt that recycling of the water would ultimately lead to a reduction in the salt input and resultant degradation of the existing underground reservoir. The project added considerable knowledge and experience to the technology of intermittent wastewater percolation and associated monitoring techniques. A novel feature of the project was the employment of highly sensitive temperature probes to trace the lateral migration of the recharged water, much of which appears to be escaping as shallow underflow to the San Jacinto River and hence not reaching the deep groundwater table
