This on-going assessment, which is renewed annually, is being conducted to assist the Fort in satisfying the requirements of a general National Pollutant Discharge Elimination System permit that authorizes the discharge of stormwater from a site associated with industrial activities (Georgia Department of Natural Resources, 2012). Thirteen sites are sampled once annually. These sites are classified by industrial activity according to Georgia Department of Natural Resources (2012) criteria and include 6 landfill sites (L Sector), 2 Defense Reutilization and Marketing Office (DRMO) sites, 1 Recycling Center site, 1 Storage Tank Disposal Yard site (N Sector), and 3 heating and cooling sites (O Sector) (fig. 3)." }, { "@type": "TextObject", "text": "INTRODUCTION" }, { "@type": "TextObject", "text": "Before the study was expanded in August 2013, the USGS collected data at five sites (fig. 3, Sites Surface Water (SWR)11-1 through SWR11-5).

During the first 30 minutes of runoff, stormwater to be analyzed for oil and grease and semi-volatile organic compounds is collected directly into individual laboratory-prepared bottles by submersing the sample bottles into the center of the runoff, taking care not to disturb any sediment. Additionally, about 4 liters (L) of water are collected from the center of the stormwater runoff into pre-cleaned plastic bottles. This water is placed into an 8-L plastic churn for compositing for analysis for total suspended solids, total and dissolved metals, oxygen demand, and nutrients. Appropriate preservation methods are applied to the processed samples and shipped overnight to the USGS National Water Quality Laboratory (NWQL) and contract laboratory. Samples are analyzed for selected constituents specified by facility type by the appropriate laboratory (Table 1) (Georgia Department of Natural Resources, 2012)." }, { "@type": "TextObject", "text": "References" }, { "@type": "TextObject", "text": "All stormwater samples are collected and processed using standard USGS and Georgia Department of Natural Resources (GaDNR) field procedures (U.S. Geological Survey, variously dated; Georgia Department of Natural Resources, 2012).
