September 2007 presentation to State Water Resources Control Board. Overview of the conceptual approach and tool development activities for assessing the direct effects of sediment contaminants in bays.
January 2007 presentation at the Remediation of Contaminated Sediments Conference. Describes the development and application of the Chemical Score Index, a sediment quality guideline based on the response of benthic macrofauna to sediment contamination.
Based on a July 2007 presentation at SCCWRP. Describes the results of an application of the sediment quality assessment tools and data integration framework to regional monitoring data in order to produce a spatial assessment of sediment quality in California embayments.
Chemistry, toxicity, bioaccumulation, and benthic community data that was collected from various California habitats including bays, estuaries, and offshore areas between 1980-2003 was compiled and integrated into this Access relational database.
This document describes the contents, system requirements, features of the Sediment Quality Objectives Database. The metadata interface and sample queries for extracting data are also described.
An Access database containing metadata (information regarding the source, characteristics, and quality of the data) for each study included in the California Sediment Quality Objectives database.
List of the chemicals required for application of the CA LRM and CSI sediment quality guidelines.
Document describing the calculations needed to interpret the chemistry, toxicity, and benthic infauna data using the sediment quality assessment tools. The calculations are illustrated using a sample data set.
This table displays combinations of the three lines of evidence (toxicity, chemistry, and benthic community) and the sequence of their integration into a single multiple lines of evidence assessment.
A listing of the site assessment categories resulting from each of the 64 possible combinations of the chemisty, toxicity, and benthich community lines of evidence. The list is sorted by chemistry category.
A description of the steps and calculations needed to apply four benthic indices. The steps include data collection, calculating scores for each benthic index, comparing the benthic index scores to threshold values, and integrating the individual index results to determine the benthic community condition classification.
List of benthic macroinvertebrate species found in California embayments including their taxonomy, pollution tolerance scores, and notes for use in benthic index calculations.
Program, habitat characteristics, and sample data files needed for calculation of the RIVPACS benthic index. User must have SAS software to run the program. Instructions for use provided in "Benthic Index Calculation Methods for California Embayments".
Habitat characteristics and sample data files needed for calculation of the RIVPACS benthic index using a web site. Web site userid and password required. Instructions for use provided in "Benthic Index Calculation Methods for California Embayments".
