PLANT PERFORMANCE

To monitor the treatment process and ensure safe standards of operation, wastewater is automatically sampled around the clock at numerous strategic locations throughout the plant. Over 5,000 laboratory tests are performed annually to monitor for impurities in an on-site, state-certified laboratory.
