SITE GEOLOGY AND HYDROLOGY Sample Clauses

SITE GEOLOGY AND HYDROLOGY. The Site is located in the central Willamette Valley on a quaternary floodplain of the Willamette and Mary’s Rivers, approximately 10 to 15 feet above the river level. The confluence of the rivers is approximately a 1/2 mile from the Site. The southern Corvallis area has been fluvially reworked by both rivers, and as a result, shallow geology consists of sedimentary deposits with varying layers of permeability. Local relief fluctuates 10 to 15 feet, and the site is situated on a terrace that forms a mound between the steep slopes of the Mary’s River on the west and north sides, and the shallow slope towards the Willamette River on the east side. The shallow geology beneath the Site consists of silt and clay (Willamette Silt) from the surface to approximately 20 to 25 feet below ground surface (bgs), and sands and gravels (Linn Gravels) from approximately 25 to 40 feet bgs. Below about 40 feet is bedrock, mostly tertiary marine turbidite rocks referred to on most of WRD well logs as sandstone. The Siletz River Volcanics may be the bedrock in some of the xxxxx in the area. Hydrogeologic information provided from other cleanup sites in the vicinity suggests that the Willamette Silt and bedrock have low hydraulic conductivity, and the Linn Gravels have high hydraulic conductivity. The Linn Gravels form the primary aquifer in the area and the impacted domestic xxxxx draw water from this aquifer. However, it is likely that the uppermost groundwater will be encountered in the Willamette Silt, and it is also likely that the Linn Gravels aquifer is hydraulically connected to the Willamette Silts throughout the area because there may be no confining layer between them. Therefore, VOC contamination in the shallower Willamette Silts, especially involving dense nonaqueous phase liquids (DNAPLs) such as TCE, is likely to readily migrate to the deeper Linn Gravels. Because water-levels have not been surveyed in xxxxx in the site vicinity, groundwater flow direction in the vicinity of the Site is unknown but thought to vary. Regional groundwater flow in the Linn Gravels is to northeast towards the confluence on the Mary’s and Willamette Rivers. Local groundwater flow in the Linn Gravels at the Site may be Xxxxx Street - PA 6 July 28, 2003 CERCLIS No. ORN001002357 to northwest due to the proximity to the Mary’s River floodplain and because of the topographic mound on which the Site is located. Local groundwater flow in the Linn Gravels may also follow regional flow to the ...
