The City of Worcester Department of Sustainability and Resilience seeks a qualified Contractor to supply polyaluminum chloride (PAC) for the Indian Lake Dosing Station through November 2026. Indian Lake is a 190-acre, shallow lake in Worcester, MA that has been listed on the 2014 Massachusetts Impaired Waters 303d List for Dissolved Oxygen and noxious aquatic plants. In 2001, the Massachusetts Department of Environmental Protection drafted a Total Maximum Daily Load for phosphorous. A large-scale algal bloom in 2014 closed Indian Lake to recreational activity for the entire summer, and high levels of cyanotoxins were recorded. Located at 110 Shore Drive in Worcester, the Indian Lake Dosing Station dispenses PAC through a diffuser in Ararat Brook to inactivate phosphorus as it enters Indian Lake, reducing biologically available nutrients and excessive cyanobacteria growth. The site has a crushed stone driveway and curb cut for a bulk delivery truck to pull off the road while unloading chemicals. Contractor must be registered as a federal contractor in sam.gov or possess a valid Unique Entity Identification number.
