a porous medium, as is the case in the report, the <br />hydraulic conductivity from the slug test will be <br />underestimated by a factor of 20/(1/2) = 40. <br />• Applying the concepts of porous medium (Report, <br />p. 19) and hydraulic conductivity (Report, p. 20) <br />to the fractured bedrock is highly questionable, es- <br />pecially for contaminant transport. <br />• The effective porosity has not been even measured. <br />The accepted value of "less than M' is taken from <br />literature [Heath, 1989] that was not subjected to <br />the stringent quality control of peer- review process. <br />• The reference relied on in establishing the flow <br />regime [LeGrand, 19881 is not listed in bibliog- <br />raphy. <br />• Report, p. 18, "[The upper aquifer] material can <br />be reasonably described as hydraulically isotropic." <br />• The 25 -year storm design criterion for storm wa- <br />ter control is highly questionable in the vicinity of <br />drinking water wells and the stream, as demon- <br />strated by the recent storm. <br />• Waste screening process in admitting waste to the <br />landfill has been assumed perfect. Note that small <br />amount of paint solvents can easily be missed and <br />can reach groundwater leaching from the landfill <br />proposed to be constructed WITHOUT A LINER. <br />
