The copper system produced some elevated lead levels and, under some conditions, potentially harmful levels of copper.^] A subsequent independent health risk assessment of the test data, conducted by CH2M Hill, concluded that PVC pipe poses no greater threat to health than copper pipe and, under some conditions, may be the preferred piping material.^] Battelle Memorial Institute undertook a series of tests in 1983 to determine whether various piping materials were susceptible to permea tion -- the phenomenon by which potential water contaminants (such as soluble fertilizers or spilled gasoline) pass through the pipe wall to contaminate the water being carried within.

After positioning the truck and trailer (see Attachment 1 'MISCELLANEOUS TRUCK, TRAILER, BLOWER, AND RELIEF VALVE DETAILS"), just east of the Compound Silos, Lindsey, Spann, and Howell connected the trailer unloading flex line to a metal transfer line leading to the boxing hopper located some 275 feet away.
