Circulated water drift3/21/2023 ![]() No foliar injury symptoms associated with salt deposition were observed in either the simulation drift studies or cooling tower monitoring program during the investigation. Results obtained from these simulated drift studies were compared with results obtained from 12 monitoring sites located at 1.6-, 4.8-, and 9.6-km distances from an operating natural-draft cooling more » tower at Chalk Point, Md. The studies involved two sources of salts (NaCl and brackish water from the Unit 3 cooling tower a Chalk Point, Md.), and various salt deposition rates (0.97 to 22.24 kg ha/sup -1/ week/sup -1/). « lessįield studies were conducted on Maryland tobacco (Nicotiana tabacum L.) for 8 weeks during each summer from 1973 to 1977, to acquire information on the response of tobacco to simulated saline aerosol deposition from brackish water cooling towers. These results suggest that the operation of the Unit 3 cooling tower using brackish water was not having a significant impact on tobacco grown in the region. In the cooling tower monitoring program, no significant (p less than or equal to 0.05) differences were observed for yield, quality, burn, Cl contents or metabollic index value with respect to distances or years X distance interaction however, year-to-year variation was significant. ![]() No foliar injury symptoms associated with salt deposition were observed in either simulation drift studies or cooling tower monitoring program during the investigation. The studies involved two sources of salts (NaCl and brackish water from the Unit 3 cooling tower at Chalk Point, Md.), and various salt deposition rates (0.97 to 22.24 kg ha/sup -1/ week/sup -1/). A portion of the first seasonal test data was used as input to drift transport models as a first step in model verification and determination of stack drift interference with measurements aimed at determining downwind cooling tower contributions. On-site meteorological data was also acquired more » over the report period and is presented in summary form. In addition, results are presented of continuous monitoring measurements wherein downwind sodium concentration, cooling tower droplet size measurements and time-lapse plume photography were acquired. ![]() Source measurements of droplet size and mineral mass emission were conducted in the Unit 3 natural draft cooling tower and scrubber stack together with downwind measurements of a number of parameters including droplet size during two Intensive Monitoring Periods (Seasonal Tests). Results of a field measurement program conducted as part of the Chalk Point fossil-fuel power plant cooling tower project for the fiscal year 1976 are presented in two volumes. ![]()
