SECTION 3.0 ENVIRONMENTAL SETTING
The APE is located within the New Jersey Inner Coastal Plain Physiographic Province (see Figure
3.1). This portion of the Inner Coastal Plain is characterized by unconsolidated clays, sands, marls,
and gravels deposited during the Late Cretaceous, Tertiary, and Quaternary geological time periods
(Widmer 1964; Wolfe 1977; Tedrow 1986). Potomac Formation Cretaceous-(Upper Member) and
Cenomanian-(Lower Member)-Age sand interbedded with clay underlie the APE (Owens, et. al.
1998).
Topographic settings within the APE vary. The SGL Surrounding Property portion of the APE is
located on an upland terrace setting that formerly overlooked the Delaware River, but currently
overlooks made-land to the west (see Figure 1.3). The remaining three sections of the APE are
situated on broad nearly flat, upland plains (see Figure 1.3). Topographic elevation ranges from 40
to 60 feet above mean sea level. Historically, the Delaware River was situated 200 to 300 feet west
of the SGL Surrounding Property section of the APE, 1,400 feet west of the Advance Process
Supply section of the APE, 2,500 feet west of the King Arthur portion of the APE, and 3,600 feet
west of the Penler Anodizing section of the APE (U.S.G.S. 1898) (see Figure 1.2). Pochack Creek,
which drains into the Delaware River, and its tributaries separate Penler Anodizing from the
remainder of the APE. The headwaters of an unnamed tributary of Pochack Creek were once
located roughly 2,000 feet northeast of the King Arthur and Advance Process Supply portions of the
APE (U.S.G.S. 1949). Further, the headwaters of a former seasonal unnamed tributary of Pochack
Creek were located 200-300 feet southeast of the Penler Anodizing section of the APE (Figure 3.2).
Specific soils mapped within the Penler Anodizing portion of the APE in 1966 consisted of
Freehold and Downer, clayey substrata-Urban Land Complex (Fy) soils (Markley 1966) (Figure 3.2).
This soil type consists of areas where either Freehold series, Downer soils, or modified soils are
present, but occupy areas too small to map individually (Markley 1966). Freehold series soils
typically consist of a nine-inch thick dark grayish brown fine sandy loam plowzone, underlain by a
six-inch thick yellowish brown fine sandy loam subsoil, followed by a 20-inch thick dark yellowish
brown sandy clay loam substratum (Markley 1966). Downer series soil profiles consist of a ten-inch
thick dark grayish brown loose loamy sand topsoil, underlain by an eight-inch thick yellowish brown
loose loamy sand subsoil, followed by a 12-inch thick yellowish brown sandy loam substratum
(Markley 1966). Urban land complex soils are comprised of soils altered by construction activities or
capped by roads, parking lots, and buildings. The SGL Surrounding Properties, King Arthur, and
Advance Process Supply portions of the APE were located in portions of Camden County in which
the soils were not characterized in the 1966 soil survey (Markley 1966) (see Figure 3.2).
