J. Favaloro pointed out that this is not a money-saving effort or a physical move, but rather an exercise on paper to reduce redundancy and increase efficiency. It is not even certain if this consolidation will take place. M. Delaney added that there will not be a reduction in services. The goal for this consolidation is July 1. Plume tracking is a field test of the dilution of the new MWRA outfall.
Dilution is used in toxicity calculations.
Using dilution and known toxic amounts of substances, one can work back to calculate how much of the contaminants can be allowed in the wastestream. Dilution was well studied using a physical model in the EPA test tank. Roberts et al. The concentration of dye was measured and dilution could then be calculated since it is the reciprocal of concentration. Minimum dilution can be looked at as the reciprocal of the maximum concentration allowable.
