| Abstract: | Data management is the foundation for water resource assessment. The ability to successfully
manage large amounts of data (>100MB to 1 GB) collected and submitted during an extended
period is essential to evaluate long-term trends, conduct modeling and determine the effectiveness
of remedial efforts. The Delaware River Basin Commission, on behalf of the U.S. Environmental
Protection Agency, has concluded the Stage 1 Total Maximum Daily Loads (TMDLs) for
polychlorinated biphenyls (PCBs) for the Delaware Estuary in December 2003, DRBC (2003).
Monitoring efforts in support of the Stage 1 TMDLs and subsequent data submission posed
significant difficulties in assimilating the analytical results into a comprehensive database. The use
of different analytical methodologies, and reporting conventions by the various laboratories
involved in this effort required extensive data manipulation and limited the usefulness of the
reported results. The Delaware River Basin Commission is currently developing the Stage 2 Total
Maximum Daily Loads (TMDLs) for PCBs for the Delaware Estuary. The objective of the Stage 2
TMDL is to develop more accurate TMDLs, which require a more precise quantification of the
concentrations and/or loads from the various PCB source categories. This task is made more
complex by the requirements to evaluate different source categories i.e. point source discharges,
ambient river water, sediment, tributary and contaminated site runoff, analysis of 209 compounds,
and the collection of multiple samples. To streamline the Stage 2 process, data quality objectives
(DQOs) were specified to provide a consistent approach to sample collection, analysis and data
reporting. |
| Description: | Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE) hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization. |
