Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (page 21). "The Tsulquate and the Airport Sewage Treatment Plants were evaluated over a 5-day period from June 9 to June 14, 1986. The plants were last evaluated in December 1978 as part of a shellfish survey of Hardy Bay and Beaver Harbour (EPS Regional Program Report 79-18). In 1978, operational problems were found at the Tsulquate STP mainly due to the contact stabilization mode of operation and the large flows during wet weather. In 1982, the mode of operation was changed from contact stabilization to extended aeration allowing easier control for the STP operator. Since 1978, the Department of Highway's facilities, the homes along Beaver Harbour and the Fort Rupert Indian Reserve have connected to the Airport STP creating a larger load on the plant. This report represents an assessment of the treatment plants under the above modified conditions. Recommendations are made to improve the final effluent quality and to protect the fishery resources in the Port Hardy coastal waters"--Abstract, page i. Issued also in print format.
