| Short Description |
During 1989 and 1990, Ecology′s Environmental Investigations and Laboratory Services Program purchased two flow-through centrifuges and installed them in an outfitted trailer. This self-contained "centrifuge system" has been used to collect suspended particles from NPDES-permitted waste-streams, rivers and storm water. This paper summarizes the general success of efforts to collect, analyze and evaluate data from these particulate samples. Issues addressed include the resources (time and money) required to obtain samples and data, and special problems encountered in analyzing the particulate samples. (Also see abstract below) | |

| Abstract | Long Description |
During 1989 and 1990, Ecology′s Environmental Investigations and Laboratory Services Program purchased two flow-through centrifuges and installed them in an outfitted trailer. This self-contained "centrifuge system" has been used to collect suspended particles from NPDES-permitted waste-streams, rivers and storm water. This paper summarizes the general success of efforts to collect, analyze and evaluate data from these particulate samples. Issues addressed include the resources (time and money) required to obtain samples and data, and special problems encountered in analyzing the particulate samples. The efficacy of using centrifuge-collected particulate data for three objectives is discussed. These objectives are to: 1) screen effluents or surface waters for the presence of compounds associated with the particulate phase; 2) quantify pollutant loads associated with the particulate phase of effluents or surface waters; and 3) use data from particulate analysis (organic chemical, TOC, grain size, etc.) to assist in modeling or otherwise predicting the impact of discharges on nearby sediments. |
