GEOCHECK® - PHYSICAL SETTING SOURCE SUMMARY Site-Specific Hydrogeological Data': Search Radius: 2.0 miles Status: Not found AQUIFLOW® Search Radius:2.000 Miles. EDR has developed the AQUIFLOW Information System to provide data on the general direction of groundwater flow at specific points.EDR has reviewed reports submitted by environmental professionals to regulatory authorities at select sites and has extracted the date of the report, groundwater flow direction as determined hydrogeologically,and the depth to water table. LOCATION GENERAL DIRECTION MAP ID FROM TP GROUNDWATER FLOW Not Reported GROUNDWATER FLOW VELOCITY INFORMATION Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional using site specific geologic and soil strata data. If such data are not reasonably ascertainable, it may be necessary to rely on other sources of information,including geologic age identification, rock stratigraphic unit and soil characteristics data collected on nearby properties and regional soil information. In general,contaminant plumes move more quickly through sandy-gravelly types of soils than silty-clayey types of soils. GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY Geologic information can be used by the environmental professional in forming an opinion about the relative speed at which contaminant migration may be occurring. ROCK STRATIGRAPHIC UNIT GEOLOGIC AGE IDENTIFICATION Era: Cenozoic Category: Stratified Sequence System: Quaternary Series: Quaternary Code: Q (decoded above as Era,System&Series) Geologic Age and Rock Stratigraphic Unit Source: P.G.Schruben, R.E.Arndt and W.J. Bawiec, Geology of the Conterminous U.S.at 1:2,500,000 Scale-a digital representation of the 1974 P.B. King and H.M. Beikman Map, USGS Digital Data Series DDS-11 (1994). DOMINANT SOIL COMPOSITION IN GENERAL AREA OF TARGET PROPERTY The U.S. Department of Agriculture's(USDA)Soil Conservation Service(SCS)leads the National Cooperative Soil Survey(NCSS)and is responsible for collecting,storing,maintaining and distributing soil survey information for privately owned lands in the United States.A soil map in a soil survey is a representation of soil patterns in a landscape.Soil maps for STATSGO are compiled by generalizing more detailed(SSURGO)soil survey maps. The following information is based on Soil Conservation Service STATSGO data. 01 Can peM1e�„vveEEnnr�aeol�i�bam gaft mm pe,EERCLI Aleft 'Iity lnlSapbbM98yeaml,WA, AS notvwlisubmd.All of lM mloMabon aM Mmom quanted am tl d ft til ad CPA,epo(Q.~am.b—ply.... nm TC788874.3s Page A-3
