Identify opportunities to optimize chlorine residual in the distribution <br /> system. <br /> d. Review historical water quality reports to identify potential problems <br /> with source-water quality. <br /> e. Estimate recycled water demands in each reach of the distribution <br /> system using historical winter recycled water consumption data for all <br /> current customers. Consultant will also estimate maximum age of the <br /> water at up to four locations in the distribution system using an existing <br /> computational model. <br /> f. Analyze baseline chlorine residual measurements at four locations in <br /> the distribution system and identify apparent discrepancies between <br /> model predictions and field measurements. <br /> g. Identify protocols for sample collection and laboratory analysis of water <br /> stains at the Maple St. Correctional (County Jail) complex.
