PACs, which include organochlorine compounds,metals, and polycyclic aromatic hydrocarbons (PAHs),pose a threat to biota in aquatic systems and humans because many are persistent,bioaccumulative, and(or) toxic (USEPA, 1997). Occurrence of PACs has resulted in the impairment of thousands of streams, lakes, and reservoirs: PACs were responsible for fish-consumption advisories for 23 percent of total lake acreage and 9.3 percent of total river mileage in the United States in 2000(USEPA, 2001), and PACs comprise more than 20 percent of total maximum daily loads (TMDLs)nationwide (USEPA, 2004). Fort Worth lakes and streams are not immune to these problems: Lakes Como, Echo, and Fosdic, and segments of the West Fork and Clear Fork Trinity Rivers are under fishing advisories or bans and are part of a TMDL for legacy pollutants(TDH, 2004; Van Metre and others, 2003). The U.S. Geological Survey(USGS) studied the occurrence and trends in PACs to the Fort Worth waterbodies listed in the TMDL and found relatively high concentrations of legacy pollutants,polycyclic aromatic hydrocarbons(PAHs), and metals in the more urban sites (Van Metre and others, 2003). They also found that the legacy pollutants and PAHs were not uniformly preserved in bottom sediments in the lakes compared to suspended sediments in the streams(Van Metre and others, 2004). Higher concentrations of pollutants in the streams than in the downstream reservoirs raises several questions, including: Are some contaminant levels in soils and street dust much higher than we think based on measurements of aquatic sediments? Are there current uses/releases of legacy pollutants in these watersheds?Does the loss of contaminant during transport indicate greater bioavailability? Are some contaminants better preserved in soils than aquatic sediments?What factors are controlling these differences? What are the primary sources of the various contaminants in these small urban watersheds? A research team from the USGS in Austin, Texas, and a group with the University of Illinois (Ul) are collaborating on a study to answer these questions. The study focuses on changes in organic carbon in soils and sediments as material is eroded from the watershed, transported in streams, and deposited in the small lakes downstream. The study includes Como and Fosdic Lake watersheds. The City of Fort Worth-USGS collaborative study proposed here will add comprehensive chemical analysis of contaminants in soils, street(and parking lot) dust, and sediment cores from the two lakes to the USGS-UI study. Together these studies should provide a much better understanding of the sources of PACs and factors affecting their transport and fate in these small urban watersheds. N (� �aAn -r,n P!i LAI OBJECTIVES The objective of this study is to characterize contaminant levels from source areas(commercial and residential soils and street and parking lot dust)and lake sediment from the watersheds of Lakes Como and Fosdic in Fort Worth,Texas. In addition,the results of this study with provide valuable information to the three-year research study by the USGS and Univ. of Illinois. APPROACH Samples of surficial material and aquatic sediment will be collected and analyzed for PACs from the watersheds of Lake Como and Fosdic Lake. Samples from each watershed will include: residential soils,commercial soils,residential street dust,parking lot dust from sealed and unsealed parking lots,and bottom sediment cores from the lake. Soil samples will be composite samples collected by scraping the top—1 cm from about 40 locations distributed randomly over a several block commercial or residential area. Sampling will target exposed soils deemed most likely to erode,the conceptual idea being to sample soil that is soon to be eroded and become aquatic sediment. About 4 L of material will be collected to provide sufficient material for all chemical analysis and analysis of organic carbon and,in selected samples, chemical sorption properties. The latter two analyses will be performed by the USGS-UI study. Soil samples will be air dried,broken up,and sieved using a 1-mm sieve to remove very coarse sand and larger material. Street and parking lot dust samples will be collected by sweeping using clean,nylon push brooms. Up to 4 L of dust will be collected from at least 3 parking lots of each type(sealed and unsealed)and from 2-3 blocks of residential roadway. These samples will be sieved using a 1 mm sieve. Lake cores will be collected using a 50-cm tall, 14-cm square box corer using methods of the USGS Sediment Research Project in Austin(Van Metre and others, 2004). Because of the need for a relatively large mass of material for the organic carbon and sorption analyses,three or four box cores will be collected from one area of each lake and composited. Composite samples will be for 5-cm intervals to a depth of about 30 cm. Sample from at least 3 intervals will be analyzed. Analyses will include major and trace elements,organochlorine pesticides,polychlorinated biphenyls(PCBs),and PAHs. Methods described and referenced in Van Metre and others,(2004)will be used. DELIVERABLES A USGS Open File Report will be produced by May 2005,presenting all chemical data. The data will also be used in the USGS-UI study and will eventually be included in publications resulting from that study. BUDGET Cost estimates include indirect costs.Most of the funding for this study will be used for laboratory analyses. Costs of sampling and some of the publication costs will be covered by other USGS programs(e.g. the USGS-UI study).
