“…At the 300 Area's southern border, a cross-river water sampling transect found that all water samples were below ambient surface water quality criteria and that slightly elevated (compared to both mid-river) concentrations of anions and total uranium were found for the Franklin County shore. The slightly elevated concentrations of anions and total uranium along the Franklin County shoreline has been observed in prior sampling efforts and likely resulted from extensive irrigation in the area (Poston et al 2001;Poston et al 2002).…”

“…It was not possible to collect all samples on the same day because of the large study area, numerous target biota, and the large amount of samples required. Water sampling dates (all in 2001) and daily (24-hour) average flow conditions for the Columbia River measured at Priest Rapids Dam (Poston et al 2002) are discussed below. The 300 Area and Vernita Bridge river water and 300 Area riverbank spring water was collected on August 27 at 2,680 cubic meters (95,700 cubic feet) per second river flow.…”

Because most changes for Rev. 1 were relatively minor, all individuals identified in the original distribution list who did not receive a copy of Rev. 1 were sent a cover letter describing the changes, a web address (http://sesp.gov/reports/reports.html) to view or print a PDF file of Rev. 1, and a copy of the Rev. 1 Preface. A limited distribution of Rev. 1 was made; however, hardcopies of PNNL-13692, Rev.1 are available upon request to Greg W. Patton at (509) 376-2027

“…Because disposed and discharged quantities of fission products could be related to the production of special nuclear materials, early records were secret and few efforts were made to develop or show total inventories of radionuclides with greater impact to man and the environment (e.g., technetium-99, iodine-129) until very near the end of Hanford's production mission.

“…Hexavalent chromium is a contaminant of concern for the Hanford Site because of its use as a corrosion inhibitor for cooling water systems in the nuclear reactors. Direct discharges of chromium to the river ended with the shutdown of the last single-pass reactor in 1971; however, residual chromium is still present in the soil column, groundwater, and some biota (Poston et al 2002.…”

This study involved the collection of juvenile fall Chinook salmon and Columbia River water samples to assess whether fall Chinook salmon were exposed to chromium that upwells into the river from contaminated groundwater originating at the Hanford Site. Juvenile fall Chinook salmon were seined and water samples were collected from three locations in the Hanford Reach during the period of juvenile salmon freshwater residency in early May, mid-May, and mid-June 2002. The concentrations of chromium in fish and river water were measured and the overall conditions of the fish were evaluated. Sample collection focused on the 100-D and 100-H Areas, which were the locations most likely to have elevated chromium concentrations in the environment based on groundwater monitoring data. The Vernita Bridge area served as an upstream reference site for all samples. All Columbia River water concentrations for chromium determined during this study were less than or equal to 0.1 µg/L, which were below the Washington State ambient surface-water quality criteria of 10 µg/L. Body burdens of chromium were not statistically different for fish collected at the 100-D and 100-H Areas compared to the Vernita Bridge location; thus, there was no indication of elevated exposure or uptake of Hanford sources of chromium. No gross morphological anomalies were noted in any fish collected during this effort. Histological assessments for fish examined during this study exhibited normal and healthy tissues and comparison of fish body lengths and weights from these locations revealed no evidence of physiological stress for organisms collected near the 100-D or 100-H Areas. Taken collectively, these results indicated that there was no impact to juvenile fall Chinook salmon from chromium released into the Columbia River from Hanford during 2002. v
