Abstract |
A three-phase analysis program for organics in water is described. In the first phase, a prototype automatic sampler was constructed to sample and concentrate organic compounds from dilute systems, including finished drinking water. The sampler collects and seals up to 26 grab samples for analysis of purgeable organics and perhaps non-volatiles. In the second phase, a general protocol for analytical surveys in which all volatile organics above a specified level in water are identified and quantified will be developed. The master analytical scheme, which incorporates modern GC-MS-computer analytical techniques, should be available in early 1980. Emphasis will be on comparison, selection, and optimization of techniques for sampling, extraction, cleanup, and separation of all gas chromatographable organics in water. In the third phase, a comprehensive data collation and retrieval system for organics in water will be developed. The system, called the Distribution Register of Organic Pollutants in Water (WaterDROP), will include a means for continual updating and dissemination of new information on organics identified in water. WaterDROP will be searchable by several parameters to locate compounds of particular interest to analytical chemists, epidemiologists, enforcement groups, and others. |
