(b,) An electronic repeating pipette. It can produce a repeatable vacuum so that the sample volume passing through the glass filter will only depend on the properties of the sample (e.g., TSS). (2) Test the system for artificial and real stormwater runoff to establish the method. Artificial runoff will be made up of silt, clays, and sand of different combinations. Real stormwater will be sampled from several construction sites. The project will establish calibration curves of TSS vs. the passed water for different runoff mixtures. The performance, statistics, and cost effectiveness of the method will be evaluated. The research is a significant, initial step in tracking TSS in the field. The method should be rapid, cost-effective, reliable and easily commercialized.]]> Wed, 05 Jun 2013 01:01:41 GMT https://rip.trb.org/View/1251920 Improving Highway Work Zone Safety https://rip.trb.org/View/1228380 Thu, 03 Jan 2013 13:19:57 GMT https://rip.trb.org/View/1228380
