The present study was conducted as a three part investigation to
(i) examine the incidence, distribution and kinds of standard plate
count bacteria present in chlorinated and raw water; (ii) study the
ecological role and possible health significance of Aeromonas spp.
in distribution water, and (iii) evaluate the effects of...
Previous studies of six Oregon public water supply systems revealed that greater proportions of the standard plate count (SPC) bacteria from distribution waters were multiple antibiotic resistant (MAR) compared to isolates from the corresponding source raw waters. In the present study, two of these water systems were examined further to...
Blood, liver, kidney, femur, and ovaries were assayed
from female Wistar rats following oral administration of
uranyl nitrate. Three uranium concentrations were
studied for six time periods ranging from 4 hours to 240
hours following gavage. Uranium burdens of tissues were
determined by neutron activation and delayed fission
neutron counting...
Water in 70 percent of the cities in the United States is hard enough that softening is either required or recommended. It is estimated that approximately 30 percent of all homes in the United States use water softeners. Water softeners, the cation exchange types suited for residential use, exchange sodium...
The removal of microbial populations from potable water has been a practice with great importance towards public health, as it has resulted in the reduction of literally millions of cases of infectious disease. In the United States, pathogenic organisms are most commonly removed from drinking water through the application of...
