With the elimination of the utilidor system where water and sewer pipes were in close proximity to each other, it is highly unlikely that any cross-contamination can now occur. Chlorine disinfection levels dropped below the state standard on three occasions in 2002 and four times in 2003 as a result of equipment failure. As chlorine levels dropped below specified standards, these incidents are considered violations. NJUS has automated alarm systems which immediately notify operators if chlorine levels drop below optimum levels. If the chlorine level drops below specifications (0.2mg/l), standard operating procedure is to collect water samples from the water distribution system to check for Total Coliform Bacteria. On each occurrence a sample was collected. All samples results confirmed the water was free of bacteria and the chlorine was restored to its optimum level in accordance with regulations. A Consumer Confidence Report (CCR) was not distributed for 2002, which is considered a violation. Rather than publishing a 2002 report separately, ADEC approved the inclusion of 2002 testing data with this 2003 report. Previously published CCRs are available from NJUS and are also posted on the web.
