Figure 1. STRATIGRAPHIC SECTION OF THE DEER PARK, TEXAS AREA SYSTEM SERIES FORMATION AQUIFER Quaternary Holocene Alluvium Chicot Upper Beaumont Lower Pleistocene Lissie Montgomery Evangeline Willis Goliad Tertiary Pliocene Fleming Miocene Burkeville Jasper Review of lithologic/textural descriptions from exploratory borings, monitoring well installation logs, and other such information indicates that the subsurface at the facility consists of sediments of the regional Beaumont Formation, with the surface soils consisting mainly the Beaumont Clay. These sediments are generally highly-plastic clays, separated by interbedded, lenticular deposits of sandy clay, clayey silt, and silty sand. The silt and sand sediments represent periods of fluvial activity, whereas the clays are mainly of marginal-marine origin. Based on differences in physical properties, the upper 140 to 150 feet of the subsurface can be divided into six distinct units. These units are referred to as Strata 1, 2, 3, 4, 5, and 6, in order of decreasing depth. Figure 2 on the next page provides general unit descriptions of these six strata. 36
Figure 2. STRATIAGRAPHY AND UNIT DESCRIPTIONS UNIT STRATUM 1 STRATUM 2 STRATUM 3 STRATUM 4 STRATUM 5 STRATUM 6 DESCRIPTION GRAY AND TAN SILTY AND SANDY CLAY AND CLAY; interbedded lenticular deposits of clayey silt, sandy silt and clayey sand throughout; general downward coarsening; clays are firm to stiff; unit thickness is approximately 20 feet. LIGHT GRAY AND RED MOTTLED CLAY; very stiff to hard; highly plastic; locally silty and sandy; few discontinuous sandy and clayey silt lenses in some areas; unit thickness is approximately 25 feet. INTERBEDDED LENTICULAR DEPOSITS OF GRAY AND TAN CLAY, CLAYEY SILT, SILTY SAND, AND CLAYEY SAND; few thin seams of fine sand; unit thickness ranges 18 - 28 feet, averaging 22 feet. RED AND LIGHT GRAY CLAY AND SANDY CLAY; interbedded lenticular deposits of clayey and silty sand and silt; lenses increase in occurrence toward base of unit; general downward coarsening; clays and sandy clays are still to hard; unit thickness is approximately 20 feet. TAN SILTY SAND AND FINE SAND; interbedded lenticular sandy clay deposits; unit thickness is often greater than 50 feet. GRAY AND BLACK CLAY; soft to very stiff; locally silty and sandy, Stratum 5/6 contact averages 117 feet below surface elevation. Historically, the Chicot and Evangeline aquifers have been used by local communities and industry as sources for drinking water and industrial process water. The nearest drinking water well lies approximately 2.5 miles directly south of the facility, producing water from the Evangeline aquifer for the city of Deer Park. Deer Park has two operational industrial water-supply wells screened in the Lower Chicot aquifer. Due to regional subsidence, industrial facilities are discouraged from pumping groundwater and encouraged to use alternate water resources. Groundwater withdrawal from the Chicot and Evangeline aquifers is controlled by the Harris-Galveston Coastal Subsidence District. The District issues an annual permit to Deer Park,which specifies the maximum volume of groundwater that can be pumped for industrial water supply. 37
