Includes bibliographical references. "In 1973, a major investigation of asbestos fibres in water and sediment samples of Lake Superior began at Canada Centre for lnland Waters. A procedure for obtaining total fibres per litre of water samples was developed. This report documents that procedure, describing problems encountered and suggested solutions, and outlining the mathematical equations for determining fibres per litre"--Abstract, p. v.
