Generation of enterococci bacteria in a coastal saltwater marsh and its impact on surf zone water quality

Article Abstract:

Enterococci bacteria (ENT) levels in the surf zone at southern California Huntington City and State Beaches are studied to find possible sources of contamination. The main source of ENT is found in a tidal saltwater marsh. Results for environmental factors in the movement of ENT are graphed with a wide array of samples.

Filtration of recombinant Norwalk virus particles and bacteriophage MS2 in quartz sand: importance of electrostatic interactions

Article Abstract:

The nature and magnitude of electrostatic interactions that develop between the Norwalk virus (rNV) and filter media appear to govern the pysicochemical filtration of the virus. Unlike the rNV, the bacteriophage MS2, which is a common surrogate for waterborne viral pathogens, could not be filtrated in natural systems because of their different electrostatic properties.

Partition infrared method for total gasoline range organics in water based on solid phase microextraction

Article Abstract:

Researchers describe here a new method for determining total gasoline-range organics in water. The water is extracted from the sample source, and placed into a small square of Teflon PFA film. As this perfluoroalkoxyethylene polymer lacks C-H bonds, extracted organics can be directly quantified. However, Teflon PFA is not commercially available in the form needed for this procedure. Thus, the film must be lightly sanded. Oversanding will increase opacity, and alter the test data. The film was then attached to a metal backplate using a ceramic magnet, and two screws to hold the magnet. Researchers tested a laboratory-created sample, and then petroleum wastewater samples to obtain very similar data.
