Abstract

This research was done to investigate the fate and transport of a simulated contaminant spill into Wachusett Reservoir using the CE-QUAL-W2 model. The reservoir is located in central Massachusetts (north east of Worcester) and was first filled in 1908. The Massachusetts Water Resource Authority (MWRA) uses the reservoir as a primary source of drinking water for the metropolitan Boston area. The 65-billion-gallon reservoir is replenished by 9 tributaries and also supplemented by the transfer of water from Quabbin Reservoir (412 billion-gallon capacity) through the Quabbin Aqueduct. This transfer is used to meet system water demands, manage the water surface elevation at the Wachusett Reservoir and improve Wachusett water quality. The MWRA withdraws reservoir water at the Cosgrove Intake (CIT) where it flows by gravity to the John J. Carroll Water Treatment Plant at Walnut Hill in Marlborough.
