Sediment sampling of proposed dredge sites in the confluence of the Snake and Clearwater rivers
The purpose of the study was to measure the concentration of dioxins in sediment proposed to be dredged from the Lower Granite Reservoir near Lewiston, Idaho, and compare it to concentrations found at the reference sites. The area to be dredged is immediately adjacent to and downstream from an effluent discharge pipe belonging to the Potlatch Corporation`s pulp mill. Information provided by the Environmental Protection Agency (EPA) indicate the need to test for dioxins and furans in sediments of waters adjacent to and downstream of pulp mill effluents because of the by-product created through the chlorination process

Ecological evaluation of proposed discharge of dredged material from Oakland Harbor into ocean waters (Phase 3 of 38-Foot Project). Volume 1, Background and appendixes A through H
At the request of the US Army Corps of Engineering (USACE), environmental studies were conducted by Battelle/Marine Sciences Laboratory (MSL) to evaluate the suitability of sediments from Oakland Inner Harbor for dredging and ocean disposal. During the Phase 3 38-Foot Project, sediment cores were collected from mudline to {minus}39 ft mean lower low water at various locations in Oakland Inner Harbor channel and allocated to six composite samples. These composites were evaluated through physical/chemical analyses, acute toxicity to sensitive marine organisms, and bioaccumulation potential. Sediment samples from individual locations were tested for physical/chemical parameters only. The results of toxicological and bioaccumulation testing may be used by USACE to determine the amount of potential dredged material from Oakland Inner Harbor channel acceptable for open-water disposal as defined by the Draft Implementation Manual (EPA/USACE 1990) and consistent with the Water Resources Development Act of 1986 (Public Law 99-662). This is Volume 1 of a two-volume data report that presents the data gathered during the Oakland Harbor Phase 3 38-Foot Project, conducted in the Fall of 1990. This data report does not include interpretation or statistical analysis of the 38-Foot data. Volume 1 includes the project background as well as a full presentation of data and results in Appendixes A through H. Volume 2 contains the remaining data in Appendixes I through L
âAt âAmen Mealsâ Itâs Me and Godâ Religion and Gender: A New Jewish Womenâs Ritual
New ritual practices performed by Jewish women can serve as test cases for an examination of the phenomenon of the creation of religious rituals by women. These food-related rituals, which have been termed ââamen mealsââ were developed in Israel beginning in the year 2000 and subsequently spread to Jewish women in Europe and the United States. This study employs a qualitative-ethnographic methodology grounded in participant-observation and in-depth interviews to describe these nonobligatory, extra-halakhic rituals. What makes these rituals stand out is the womenâs sense that through these rituals they experience a direct con- nection to God and, thus, can change reality, i.e., bring about jobs, marriages, children, health, and salvation for friends and loved ones. The ââamenââ rituals also create an open, inclusive womanâs space imbued with strong spiritualâemotional energies that counter the womenâs religious marginality. Finally, the purposes and functions of these rituals, including identity building and displays of cultural capital, are considered within a theoretical framework that views ââdoing genderââ and ââdoing religionââ as an integrated experience

Chemical evaluations of John F. Baldwin Ship Channel sediment phase 2
In August of 1990, the battelle/Marine Sciences Laboratory (MSL) conducted a program of sampling, geologic characterization, and chemical analysis of sediments from five sites in the West Richmond reach of the John F. Baldwin Ship Channel in San Francisco Bay. Additional sediment samples were collected for the USACE Waterways Experiment Station (WES) Wetlands and Uplands testing programs. The objective of the MSL study of the five West Richmond sites was to determine the physical characteristics and chemical contaminant levels in sediments proposed for dredging. Metals concentrations were comparable to or lower than those reported in the Phase 1 study. Butyltin concentrations were very low, and organic contaminants (PAH, PCB and pesticides) were not detected. Differences between Phase 1 and Phase 2 results may be explained by the fact that Phase 2 stations are outside the shipping channel. 16 refs., 4 figs., 16 tabs

Measurement and estimated health risks of semivolatile organic compounds (PCBs, PAHs, pesticides, and phthalates) in ambient air at the Hanford Site
Air samples for polychlorinated biphenyls (PCBs), chlorinated pesticides, phthalate plasticizers, and polycyclic aromatic hydrocarbons (PAHs) were collected at three Hanford Site locations (300-Area South Gate, southeast of 200-East Area, and a background location near Rattlesnake Springs). Samples were collected using high-volume air samplers equipped with a glass fiber filter and polyurethane foam plug sampling train. Target compounds were extracted from the sampling trains and analyzed using capillary gas chromatography with either electron capture detection or mass selective detection. Twenty of the 28 PCB congeners analyzed were found above the detection limits, with 8 of the congeners accounting for over 80% of the average PCB concentrations. The average sum of all individual PCB congeners ranged from 500-740 pg/m{sup 3}, with little apparent difference between the sampling locations. Twenty of the 25 pesticides analyzed were found above the detection limits, with endosulfan I, endosulfan II, and methoxychlor having the highest average concentrations. With the exception of the endosulfans, all other average pesticide concentrations were below 100 pg/m{sup 3}. There was little apparent difference between the air concentrations of pesticides measured at each location. Sixteen of the 18 PAHs analyzed were found above the detection limit. Phenanthrene, fluoranthene, pyrene, fluorene, chrysene, benzo(b)fluoranthene, and naphthalene were the only PAHs with average concentrations above 100 pg/m{sup 3}. Overall, the 300 Area had higher average PAH concentrations compared to the 200-East Area and the background location at Rattlesnake Springs; however, the air concentrations at the 300-Area also are influenced by sources on the Hanford Site and from nearby communities

Investigation of potential polychlorinated biphenyl (PCB) contamination on Hanford site arc-loop roads
Two roads on the Hanford Site, which had been treated during past Site operations with oil for dust suppression, were analyzed for potential polychlorinated biphenyl (PCB) contamination. The general locations of these roads are (1) off Washington State Route 240, north of Horn Rapids Dam, and (2) between the 200 East and 200 West areas, south of the 200 Area fire station. Each road had an intact crust of oil/tar on top of the underlying soil surface. A set of control samples were collected at an untreated soil site near the Prosser Barricade air sampling station. Samples were collected of the oil/tar surface crust, the soil immediately beneath the surface crust (0 - 3 cm below the crust), and a deeper soil sample (13 - 23 cm below the surface crust). Samples were collected at two locations on each road. The PCBs were extracted from the samples using a roller technique with methylene chloride, cleaned using column chromatography and high-pressure liquid chromatography, and analyzed by capillary gas chromatography using electron capture detection. The samples were analyzed for PCBs as the following technical mixtures: Aroclor 1242, Aroclor 1248, Aroclor 1254, and Aroclor 1260. All samples at all locations were less than the following detection limits: surface crust (41 ug/kg dry weight) and soil (2.1 ug/kg dry weight). These concentrations are below the U.S. Environmental Protection Agency (EPA) Region IX preliminary remediation goals for PCBs in residential soil (66 ug/kg) and well below the preliminary remediation goal for PCBs in industrial soil (340 ug/kg)

Ecological evaluation of proposed discharge of dredged material from Oakland Harbor into ocean waters (Phase 3 A of -42-foot project)
The Battelle/Marine Sciences Laboratory (MSL) conducted a study to detemine whether dredged sediments from Oakland Inner and Outer Harbors were, suitable for ocean disposal. Nineteen test treatments, six reference treatments, and control treatments were tested for physical/chemical parameters, water column effects, dredged sediment-toxicity, and bioaccumulation potential. Physical/chemical parameters were analyzed at each site and each composite sediment to a depth of -44 ft MLLW. These parameters included analysis for geological characteristics, conventional sediment measurements (grain size, total volatile solids, total organic carbon, oil and grease, and total petroleum hydrocarbons), metals, polynuclear aromatic hydrocarbons (PAHs), pesticides, butyltins, and polychlorinated biphenyls (PCBs). Physical/chemical data were used in support of the toxicological and bioaccumulation testing, but were not used in the decision-making criteria described iti the Draft Implementation Manual under Tier III testing. To evaluate water column effects, MSL conducted suspended-particulate-phase (SPP) tests using the mysid shrimp Holmesimysis sculpta, speckled sanddab Citharichtys stigmaeus, and larvae of the pacific oyster Crassostrea gigas- Both a 48-h and a 96-h test were performed. The MSL evaluated dredgedsediment toxicity by conducting a total of eight solid-phase toxicity tests using the following organisms: the bivalve clam Macoma nasuta, the polychaste worm Nepthys caecoides, the speckled sanddab C. stigmaeus, and the arnphipod Rhepoxynius abronius. Test duration ranged From 10 to 28 days. Bioaccumulation potential was evaluated in the 28-day M. nasuta and N. caecoides solid-phase exposures by measuring the Contaminants of concern present in their tissues after exposure to test, reference, and control sediments
