Trumark Companies - Baseline Water Quality Monitoring Program


ADH conducted baseline water quality sampling of two water bodies that flow through the proposed Gentry-Suisun Development Project. The project site comprises approximately 171.5 acres of currently undeveloped land south of SR 12 and west of the Union Pacific Railroad tracks. The land is currently in an unincorporated area of Solano County, and will be annexed into the City of Suisun City as part of the proposed project.
Preparation
ADH reviewed available data and documents pertaining to water quality conditions on the project site and areas upstream of the site that may effect on site water quality. These data and documents, including relevant portions of the draft EIR, documentation of the proposed sampling locations, and available environmental regulatory agency databases and reports were included in the data analysis and interpretation report.
Field Sample Collection
ADH collected water samples on one occasion from two locations: One site each in Ledgewood Creek and Petonia Slough that were located using a portable GPS unit. Field measurements of temperature, pH, conductivity, salinity, dissolved oxygen, and turbidity were measured and recorded on a field log sheet. Additional site observations noted for each site included weather conditions, stream bank conditions, flow characteristics, presence of floating materials, oil sheen, foam, trash, and biological activity.
Data Analysis and Reporting
A letter-format report was prepared that included a description of methods employed, field observations, analytical data, results of site comparisons, comparisons to water quality standards and guidelines, and interpretation with respect to site conditions or background/ upstream data.
