^'jhe results for each compound and/or sample type were averaged by unit and then ranked from the highest concentration to the lowest concentration. The values presented in the tables represent the average concentration detected per unit. The average concentration calculation included samples that were identified as below the detection limit. These samples were assigned a value equal to the detection limit. The sample size for each unit was generally either four or five samples. Unit 4B was not included in the rankings because no micro vacuum samples were collected for lead before cleaning.
