HABER GOLD PROCESS (HGP) PASSED CALIFORNIA'S DEPARTMENT OF HEALTH SERVICES STRINGENT AQUATIC TOXICITY TESTS Note the test requires 50% animal survival rate after 96 hours-the Haber Gold Process better this requirement: HGP had an 85% to 100% survival rate. Also; comparison of metals content in #1 Head Solution versos #4 Spent Solution clearly shows no leach out of toxic raw metals with the Haber Gold Process (HOP), which is a common environmental hazard with cyanide: ================================================================== 24 March 1988 Edward S. Babcock & Sons. Inc. P.O. Box 432 Riverside, California 92502 Dear Mr. Babock: Enclosed are the results of the California Department of Health Services 96-Hour Acute Aquatic Toxicity Bioassay performed on the .4 HOP Spent Solution sample submitted on 14 March 1988. MBC utilized the latest California Department or Health Services procedures for testing the sample. The #4 HOP Spent Solution sample submitted PASSED the 96-hour acute toxicity testing at all concentrations tested. Currently, Title 22, Section 66696, Article II or the California Administrative Code requires wastes to pass the 96-hour aquatic toxicity testing with greater than 50% survival at the 500 mg/t concentration for compliance.
