Further <br /> field-testing should be completed to enlarge the data set, how,rovor,tho initial data cloarly shown tho d©trament to <br /> accuracy which purging creates <br /> MU S aUORRAP V <br /> U.S E P A <br /> Procedures Manual for <br /> 1 Fenn, et al 198$ Groundwater Monitoring at Solid EPJV530/SWt311, <br /> Waste Disposal Factlitses <br /> 269p <br /> Manual of Groundwater National Water Well <br /> 2 Scalf at al 1981 Sampling Procedures Association, Dublin,OH <br /> U S Geological Sury®y, <br /> Wilson and Development of a primer on <br /> 3 Dworkin 1984 crater well sampling for volatile Reston.VA <br /> organic substances <br /> 44p <br /> Groundwater <br /> Sampling Groundwater for V g, No 12 <br /> 4 Petgyjohn,pt al 19t31 Organic Contaminants <br /> ® p 180-189 <br /> GROUNDWATER, <br /> Methodology for monitoring <br /> 5 Humenick at al 1980 groundwater at umnlum solutlon V 7 No 4, <br /> mines <br /> P 82-89 <br /> Proceedings of the Third Annual <br /> A laboratory investigation of the Symposium on Groundwater <br /> Purging Behavior of small Monitoring and Aquifer <br /> 6 Unwin and Huss 1983 g 9 Restoration National Water <br /> Diameter monitoring well Well Association Dublin,OH, <br /> p.257-262 <br /> GROUNDWATER, <br /> Barcelona, Laboratory F-valuation of <br /> 7 illi J .et al 1984 <br /> Groundwater Sampling V 7 No 4, <br /> Mechanisms <br /> p 82-89 <br /> 3rZ4199 a zl Yi+'t <br /> 14 of 14 <br />
