1. Tsan-Liang Su, Ph. D. and Mahmoud Wazne, Ph. D. Stevens Institute of Technology Hoboken, New Jersey, USA Questor Research Proposal Presentations November 17, 2009 On-Site Low Levels TPH Screening Device in Water and Soil

2. Background  Proposed TPH screen device to replace current TPH test method (EPA 418.1)  Develop an on-site TPH screen device and procedure to determine low levels of TPH in soil and water Approach – Two main features  Raman Spectrometry probe associated with a potable Raman Spectrometer  A mathematical model for data

3. Benefits & Applications On-site and Real-time Analysis Capability  Waste Water Treatment Monitoring mReal-time monitoring or earlier detection of TPH to assess the impact of discharges on the water quality  Waste Water Treatment Monitoring mReal-time Drinking water quality control  Groundwater Monitoring
