ethene, chloroform, toluene) in groundwater samples at mg/L concentrations.
10. Which EPA method you would use for the analysis of industrial wastewater sludge for
cadmium, mercury, and chromium to evaluate whether the sludges can be disposed in a
nonhazardous waste landfill.
11. Which EPA method you would use for the analysis of semivolatile and nonvolatile

18. Describe the difference between PE/LCS and MS/MSD.
19. Explain what type of the field QC samples should be used in the following cases:
(a) To know if a bailer is contaminated in the groundwater sampling.
(b) To know if airborne contaminants will be responsible for sample contamination
during shipment from and to the lab.
(c) To know if an error (trace contamination) could occur during the entire sampling
operation, shipment, and handling.
(d) To know if any sample variation exists in the field.
