Hope Valley Reservoir (South Australia) – Giardia

“…The Atrazine contamination follows the shutdown of Hope Valley Reservoir after the parasite giardia was discovered – and the discovery of cryptosporidium in Myponga Reservoir on August 31. EPA evaluation branch manager said because Atrazine was a potent herbicide with a long life, the waterway would be contaminated for another year.” The Advertiser (Adelaide) September 17, 1998 p3
