I recently compared a Consumer Confidence Report I received with one from a friend in the adjacent city. His report included contaminants which were not included in my report. Is my local water system not accurately reporting everything?
No. The table found in the consumer confidence report (CCR) normally contains information concerning contaminants that have been detected only. A detected contaminant is any contaminant detected at or above its minimum detection limit (MDL). According to the Consumer Confidence Report Rule (63 FR 44512; August 19, 1998), contaminants that are not detected or that are detected below the MDL do not need to be included in the table in the CCR. Therefore, most likely, the contaminants not found on your report were either not detected or were detected below the (MDL).
