Ongoing monitoring for the odour causing microbial metabolites Geosmin and 2-

methylisoborneol (MIB) was performed during the period February 2006 to January 2007 in

the towns of Maffra, Coongulla and Glenmaggie due to an ongoing algal bloom experienced

in Lake Glenmaggie and the Macalister River. These compounds had been a concern for

Gippsland Water in the previous year and were removed by an additional process of

activated carbon treatment at the water treatment plants.
