Preventative Treatment for Harmful Algal Blooms at Indian Lake

For Immediate Release: 5/18/2020 3:37 pm

Indian Lake on Thursday, May 21 will be treated with aluminum sulfate, also known as alum, to curb the growth of harmful algae

Alum is a safe and effective way to control the growth of harmful, toxin-producing algae by removing phosphorus from the water. The application of alum is a common practice to maintain a healthy lake and poses minimal risk to humans and animals after application is complete. The application is coordinated with the Indian Lake Watershed Association and has been approved by the Worcester Conservation Commission.

If you have any questions, please call the Department of Public Works and Parks Customer Service Center at 508-929-1300.

In addition, all visitors to the beach are reminded that swimming remains prohibited under Gov. Baker's orders because of COVID-19. Anyone visiting the beach is encouraged to maintain proper social distancing of at least 6 feet.
