Title: Livestock wastes and agricultural drainage - effects on water quality - a case study in the Pittock Watershed in Southwestern Ontario
Author: Thornley, S.; Bos, A. W.
Abstract: An evaluation of the impacts of livestock management practices on water quality was carried out in a Southwestern Ontario watershed in response to continual downstream beach closures and fish kills. The 90 mi2 area of investigation contains over 300 livestock farms. Elevated levels of bacteria. and nutrients were found to be orders of magnitude higher than Provincial Guidelines and Objectives at most sampling points. In fact, effluent from under?drainage systems in headland areas showed bacterial and chemical characteristics comparable in quality to domestic sewage. From a survey of 98 of the basin farmers, it is deduced that ignorance of the problem and economic pressures on livestock farmers together are the major contributing factors.
