Data Series 233
The primary purpose of this study was to monitor changes in contaminant composition and concentration in the air and water during the construction and operation of a major thoroughfare being built upwind of the Sweetwater Reservoir. To accomplish this, the study was divided into two phases. Phase One sampling was designed to establish baseline conditions for target compounds (primary sampling) in terms of detection frequency and concentration in air and water. Phase Two sampling is planned to continue during and after construction of the roadway to assess the chemical impact this alignment project may have on the water quality in the reservoir. In addition to the ongoing data collection, six special studies were initiated during the reporting period of Phase One to assess the occurrence of specific chemicals of concern, such as moderate-use pesticides and degradates, trace metals, and wastewater compounds in water samples.
Many compounds were analyzed to provide a better understanding of the effects urbanization may have on a drinking-water reservoir. Before any reservoir water was sampled, depth profiles were made of temperature, pH, dissolved oxygen, and specific conductance which were measured at each reservoir sampling location (table 2). Analytical results for the primary water sampling are given in tables 3 and 4. Analytical results for the primary air sampling are given in tables 5A–7A. Data for the six special studies are given in tables 8–13. Quality-control data for water samples are given in tables 14 and 15. Quality assurance data for air sampling are given in tables 16A–20A. Quality-control data for two special studies are given in tables 21 and 22.
