Workers are going to be putting aluminum sulfate in Lake Auburn next week to fight algae.
The Auburn Water District and Lewiston Water Division agreed to apply an algaecide to the lake last September. The aluminum sulfate will be applied to three quarters of the lake starting Wednesday.
The treatments follow an algae bloom last summer that was caused by phosphorus from stormwater runoff and higher-than-average temperatures. The public water supply remained safe to drink, but there were complaints about the taste and odor of the water.
Auburn Water & Sewer Superintendent Sid Hazelton said the treatment will buy time to implement additional watershed protection efforts.
