1.d. Overview <strong>of</strong> <strong>South</strong> <strong>Wilmington</strong> Environmental CharacteristicsThis section includes brief overviews <strong>of</strong> the physical and environmental characteristics <strong>of</strong> the <strong>South</strong><strong>Wilmington</strong> study area. For a more detailed discussion <strong>of</strong> the environmental conditions and issues in<strong>South</strong> <strong>Wilmington</strong>, please refer to the complete <strong>South</strong> <strong>Wilmington</strong> SAMP EcologicalCharacterization.The Christina River watershed<strong>South</strong> <strong>Wilmington</strong> is located within the Christina River Basin, which occupies 565 square miles inPennsylvania, Maryland, and <strong>Delaware</strong> and includes four major watersheds. The <strong>South</strong> <strong>Wilmington</strong>area is located within the Christian River watershed (78 square miles) and the tidal Christina Riversubwatershed (22 square miles) (Water Resources Agency, 1998).Overall, waters in the Christina River Basin, including ground and surface waters, supply 75 percent<strong>of</strong> public water for residents in New Castle County, <strong>Delaware</strong> (Water Resources Agency, 1998). Tothe City <strong>of</strong> <strong>Wilmington</strong>, the Christina River watershed provides public and industrial water supplies,with the bulk <strong>of</strong> water sourced from surface waters due to thin (low-yield) aquifers in the area(Kauffman, Wozniak, & Vonck, 2003). The Christina River also provides recreational opportunities,such as fishing and boating, and transportation for ocean-going vessels through the Port <strong>of</strong><strong>Wilmington</strong>.Water qualityThe Christina River watershed is subject to a host <strong>of</strong> water quality problems, caused largely by urbanrun<strong>of</strong>f, hazardous/superfund sites, and combined sewer overflows.The tidal Christina River subwatershed was characterized in 1998 has having extremely high totalsuspended sediment (TSS) loads (Water Resources Agency, 1998). TSS is <strong>of</strong>ten used as anenvironmental indicator <strong>of</strong> watershed health; in high concentrations, sediment suspended in thewater column can be a source <strong>of</strong> water quality problems, such as water treatment issues, habitat loss,and impairment <strong>of</strong> recreational uses. Additionally, many pollutants such as metals, nutrients, andtoxins bind to sediment and enter the water column during run<strong>of</strong>f. A TSS load above 600 poundsper acre per year (lb/ac/yr) is considered “high.” With a TSS <strong>of</strong> 928 lb/ac/yr, the tidal ChristinaRiver subwatershed had the second highest TSS load in the entire Christina River Basin (WaterResources Agency, 1998).As urban development increases, the amount <strong>of</strong> land covered with impervious surfaces alsoincreases, causing environmental problems such as water pollution and flooding. Impervious coverincludes man-made surfaces, such as buildings, roadways, or pavement, into which water can notinfiltrate and therefore runs <strong>of</strong>f to the nearest waterbody. Studies indicate that water quality, habitats,and wetlands suffer when greater than 10 to 20 percent <strong>of</strong> an area is covered by impervious surfaces;<strong>of</strong> the tidal Christina River subwatershed, 44 percent is impervious cover (Water Resources Agency,1998).Using several criteria, including TSS and percent impervious cover, in 1998, the tidal Christina Riversubwatershed was one <strong>of</strong> thirteen Christina River Basin subwatersheds identified as having a “highpollution potential” (Water Resources Agency, 1998).12Chapter 1: Introduction
