  • Poliovirus adsorption by soil particles in seawater

    Creator:
    Jakubowski, W. (Walter)
    Abstract:
    This investigation was initiated in an attempt to delineate some factors affecting the adsorption of poliovirus to soil particles in seawater. The results could have significance in the development of assay procedures for viral contaminants in natural waters. A sample of marine sediment, obtained from an estuary near Purdy, Washington,...

  • Bacteria-phosphate interactions in Upper Klamath Lake sediments

    Creator:
    Harrison, Michael John
    Abstract:
    Interactions between sediment bacteria and available phosphate necessary for algal production in a eutrophic lake were studied. Twenty percent of the organisms isolated solubilized phosphate forms such as CaHPO₄, Ca₃(PO₄)₂, FePO₄, Mg₃(PO₄)₂ and Al₂(PO₄)₂. Solubilization of phosphates occurred under conditions of aerobic growth. Upon quantitative analysis, some isolates were capable...

  • Specific indicator organisms can define the magnitude and origins of non-point pollution in rural environments

    Creator:
    Lamka, Karla Gail
    Abstract:
    A comprehensive study was made on the impact to surface and ground water pollution by a recently populated rural neighborhood located in the foothills of western Oregon. A stream originating in a limited access forest and flowing through a modern zoned housing development was routinely monitored. Sampling was performed during...

  • Persulfate oxidizable carbon as an index of organic pollution in wastewater

    Creator:
    Purkerson, L. Lee
    Abstract:
    Methods for the detection and measurement of waste materials in water have lagged far behind the many complex problems facing workers in the water pollution field. The present study introduces a new method for the detection and measurement of organic pollution in water. This new method, the persulfate oxidation, is...
