Abstract

A preliminary survey of Oak Ridge Operations (ORO) facilities was made to determine if the Legionnaire's Disease Bacterium (LDB) was present in cooling tower water. Total numbers of the bacterium per liter of water were determined, and in some cases isolation of infectious bacteria was attempted. Most of the test cooling towers from the X-10 site had concentrations of LDB in excess of 1 x 10/sup 6//L of basin water. Infectious LDB was isolated from one of the water samples. Some towers from the Y-12 site were also found to contain in excess of 1 x 10/sup 6/ LDB/L of water. With two exceptions, tower samples from the K-25, Portsmouth, and Paducah sites had less than 1 x 10/sup 6/ LDB/L of water. Except for the ORAU Medical Division cooling tower, ORAU cooling towers also had less than 1 x 10/sup 6/ LDB/L of water. The results indicate that chromate treatment is generally effective in preventing high levels of LDB. The results also suggest the desirability of a continuing monitoring program for ORO cooling towers so that concentrations of LDB in the towers can be controlled at reduced levels.

Presence of pathogenic microorganisms in power-plant cooling waters. Final report, October 1, 1981-June 30, 1983

Technical Report Tyndall, R L

Air was sampled at the point of discharge and at short distances downwind and upwind from industrial and power-plant cooling towers. Both high-volume electrostatic and impinger type samplers were used. Concentrates of the air samples were analyzed for Legionnaires' Disease Bacteria (LDB). In some cases, the samples were also tested for the presence of free-living amoebae. The concentrations of LDB in the air samples were well below the minimal infectious dose for guinea pigs and precluded testing of the samples for infectious LDB. Results of LDB analysis were related to the meteorological conditions at the time of sampling. Generally, themore »« less
Legionnaires' Disease Bacteria in power plant cooling systems: downtime report. Final report

Technical Report Tyndall, R L ; Solomon, J A ; Christensen, S W

Legionnaires' Disease Bacteria (Legionella) are a normal part of the aquatic community that, when aerosolized, can be pathogenic to man. The downtime study was designed to determine the degree to which Legionella populations are aerosolized during cleaning and maintenance operations in a closed-cycle steam-electric power plant. Both high-volume and impinger air samples were collected prior to and during downtime operations. Emphasis was placed on sampling inside or adjacent to water boxes, condensers, and cooling towers. Control air samples were taken upwind from the plant site. Water and sludge samples were also collected at various locations. In the laboratory, the concentrationsmore »« less
Concentration, serotypic profiles, and infectivity of Legionnaires' Disease bacteria populations in cooling towers

Conference Tyndall, R L

At the Philadelphia American Legion Convention in 1976 nearly two hundred people developed pulmonary infection. Of these, twenty-eight died. The causative bacterial agent was subsequently isolated and identified as a previously undiscovered human pathogen, that is, Legionnaires' Disease Bacterium (LDB). Currently it is estimated that over one hundred thousand cases of Legionella occur annually. Cooling towers have been shown to be the source of LDB in some of the outbreaks. Ecological information indicates that the bacteria are present in many natural waters. Moreover, there is strong evidence that algal products can stimulate the growth of LDB. Because cooling tower environmentsmore »« less
Legionnaires' Disease Bacterium in power-plant cooling systems: Phase 1. Final report

Technical Report Christensen, S W ; Solomon, J A ; Gough, S B ; ...

A survey was undertaken of the distribution, density, viability, and infectivity of Legionnaires' Disease Bacteria (Legionella) in power plant cooling systems. Water samples were collected during each of the four seasons at various locations within each of nine power plants and from ambient waters at each site. Measurements of a number of physical and chemical characteristics were made, and Legionella profiles (density, viability, and infectivity for guinea pigs) were obtained. Legionella were detected in nearly all samples. Water from closed-cycle cooling systems frequently had lower densities of Legionella than the ambient water. Nonetheless, infectious Legionella, as defined by their isolationmore »« less
