This book was released on 1993 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quarterly biomonitoring tests were performed for one year on composite effluent samples taken-from the Ft. Detrick (Frederick, MD) wastewater treatment plant. The cladoceran (Ceriodaphnia dubia) and fathead minnow (Pimephales promelas) acute 48-h LC50 tests were used to evaluate the toxicity of the effluent for two quarters. The cladoceran 7-d survival and reproduction test and the fathead minnow 7-d survival and growth tests were used for two quarters. The effluent was not toxic to the cladoceran or fathead minnow when tested in both acute and chronic bioassays. One priority pollutant analysis was conducted on a composite effluent sample. The analysis showed that four (Cu, Pb, Ni, and Zn) of 12 heavy metal priority pollutants were present in the effluent. The concentrations of the four heavy metals, with the exception of lead for chronic exposure, were below the U.S. EPA numerical water quality criteria for acute and chronic toxicity of the metals to freshwater organisms. The freshwater chronic criteria value for lead is 3.2 ug/L; 6 ug/L were found in the effluent sample. Two volatile organics (bromodichloromethane and dibromochloromethane) were also detected. Both halomethanes were well below the U.S. EPA numerical water quality criteria for acute toxicity to freshwater organisms; no Biomonitoring, Bioassays, Priority pollutants, Acute toxicity, Chronic toxicity, Cladoceran, Ceriodaphnia dubia, Fathead minnow, Pimephales promelas, Wastewater treatment plant, WWTP. criterion is available for chronic exposure to halomethanes.

Download or read book Evaluation of Biomonitoring Systems for Assessment of Contaminated Water and Sediments at U.S. Army Installations - Continuous Acute Toxicity Biomonitoring of Aberdeen Proving Ground-Edgewood Area Old O-Field Groundwater Treatment Facility Effluent written by and published by . This book was released on 1996 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Old 0-Field is a hazardous waste disposal site at the Aberdeen Proving Ground-Edgewood Area, Aberdeen, Maryland, which has contaminated the underlying groundwater. The contaminated groundwater is collected and treated at the Old 0-Field Groundwater Treatment Facility (GwTF) with subsequent discharge to the Gunpowder River. An in-line automated fish ventilatory biomonitoring system was installed at the GWTF to monitor the effluent for unexpected toxicity as it is discharged. A number of out of control events (stressed fish) occurred during the study (June 23, 1995 to March 31, 1996). The total number of days the system obtained out of control responses was 21.0 d. Explanations for the out of control responses were available for 20.6 d. No obvious explanations were apparent for 0.5 d. The out of control responses occurred from (1) changes in effluent water quality; (2) power failures; or (3) a proportional diluter failure. Changes in effluent water quality accounted for 89.2% of the total out of control responses with explanation. Loss of power and a diluter malfunction accounted for 5.9% and 4.9% of the out of control responses with explanation, respectively. Out of control responses with no explanation occurred 0.2% of the time or 0.5 d during the study. No acute toxicity attributable to the GWTF effluent quality occurred during the study.

Download or read book Evaluation of Biomonitoring Systems for Assessment of Contaminated Water and Sediments at U.S. Army Installations - Aquatic Toxicity Evaluation of Selected Sites During High Surficial Aquifer Flow at J-Field Aberdeen Proving Ground - Edgewood Area written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The surficial aquifer in the vicinity a the toxic burning pits (TBP) at J-Field, Aberdeen Proving Ground, Maryland, is contaminated with a number of chlorinated aliphatic hydrocarbons. The steepest hydraulic gradient in the TBP area is to the southeast toward a marsh. Recharge of the aquifer appears to be greatest in the winter and least in the summer. Flow reversals may take place in the summer. Toxicity in the marsh has been previously detected by several studies. The current study was initiated to define potential toxicity to the marsh ecosystem that may occur as a result of changes in the seasonal flow pattern of the contaminated surficial aquifer discharge into the marsh under high and low aquifer flow conditions. The toxicity of the marsh surface waters, marsh surficial sediments, and a highly contaminated surficial aquifer well up-gradient from the TBP marsh under high aquifer flow conditions, were similar to those observed in previous studies. The current study did show, however, that all three media caused malformations in a frog assay which had not previously been reported. Chemical analyses showed that the chemicals of concern were within an order of magnitude or less of those previously reported.

Aberdeen Proving Ground-Edgewood Area Wastewater Treatment Plant written by and published by . This book was released on 1992 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: An evaluation of several biological monitoring techniques for hazard assessment of potentially contaminated effluent was conducted at the Aberdeen Proving Ground-Edgewood Area Wastewater Treatment Plant (APG-EA WWTP), Aberdeen Proving Ground, MD, from January 1989 to December 13, 1989. An array of biomonitoring tests structured in a tiered hazard assessment framework was used in the evaluation of the effluent. Several levels of biological organization were included in the array of tests. Acute toxicity was evaluated on 24-h composite samples using a 15-min Microtox R assay which employs microbial (Photobacterium phosphoreum) bioluminescent activity. Two 24-h LC50 rotifer (Brachionus rubens) toxicity tests were conducted using 24-h composite samples The following chronic tests were all performed two times using 24-h composite samples: 96-h EC50 algal (Selenastrum capricornutum) growth test, 7-d daphnid (Ceriodaphnia dubia) survival and reproduction test, and 7-d fathead minnow (Pimephales promelas) survival and growth test. Generally, the acute rotifer tests and all chronic tests were conducted during the same periods in order to compare toxicological responses between biomonitoring systems ...

Book excerpt: An evaluation of several biological monitoring techniques for hazard assessment of potentially contaminated effluent was conducted at the Aberdeen Proving Ground Wastewater Treatment Plant (APG-WWTP), Aberdeen Proving Ground, MD, from early May 1990 to February 13, 1991. An array of biomonitoring tests structured in a tiered hazard assessment framework was used in the evaluation of the effluent. Several levels of biological organization were included in the array of tests. Acute toxicity was evaluated on daily 24-h composite samples using a 5- and 15-min Microtox assay which employs microbial (Photobacterium phosphoreum) bioluminescent activity. Three 24-h LC50 rotifer (Brachionus rubens) toxicity tests were conducted using 24-h composite samples.

Book Synopsis Biomonitoring Methods for Drinking Water Protection by :
Download or read book Biomonitoring Methods for Drinking Water Protection written by and published by . This book was released on 2004 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two biomonitoring approaches are being developed to rapidly identify toxicity associated with toxic industrial chemicals in Army drinking water supplies. An aquatic biomonitor continuously monitors water at fixed facilities such as water treatment plants by identifying changes in fish ventilatory and movement patterns. The biomonitor responds within an hour to most chemicals at acutely toxic concentrations. In field testing at two water treatment facilities (Fort Detrick, MD and New York City) the biomonitor has been on-line at least 94% of the time and has identified toxic events at each site. The aquatic biomonitor is being transitioned to a commercial partner and will be available for use at Army facilities in FY05. To apply the biomonitoring approach to Army field water situations, an Environmental Sentinel Biomonitor (ESB) system is being developed. An Integrated Product Team (IPT) of Army users identified ESB system use scenarios and downselection criteria for cell-based toxicity sensors. Using a formal decision analysis approach, an expert panel applied the criteria to 35 technologies. recommending 14 for further testing. These toxicity sensors are now being tested against a set of 15 chemicals. The best sensor (or set of sensors) will undergo further development as part of the ESB system. which is scheduled for completion in FY05.
