MBC is certified to conduct California State Department of Health Services Title 22 bioassays and NPDES toxicity tests, and has been involved in both laboratory and field toxicity testing work since 1978. MBC facilities include an environmentally controlled laboratory with sub-systems for maintaining appropriate experimental environments. MBC routinely performs various acute and chronic aquatic toxicity tests and has conducted over 3,000 studies including 96-hour acute and chronic aquatic toxicity, 20-day bioaccumulation, and 120-day chronic exposure tests.
Materials evaluated have included potentially hazardous wastes, cooling water effluents, complex sanitation effluents, production waters, underground tank wastes, dredge spoils, drill muds and cuttings, heavy metals, and various petroleum products.
