Description

This document outlines the policies followed by Alberta Environment staff when developing municipal effluent limits for approvals under the Environmental Protection and Enhancement Act. General procedures interpreting these polices are provided and further detailed in associated procedures manuals. The objective is to ensure that: the most appropriate pollution prevention and control technologies are adopted; and the receiving stream is protected.

Description

The Code of Practice for Watercourse Crossings establishes the objectives, standards and conditions to be met when undertaking the activity of constructing or removing watercourse crossings. Alberta Environment, as the department responsible for the administration of the Water Act, monitors and audits for compliance, and enforces the Code of Practice requirements. This guide is intended to assist those responsible for watercourse crossing in meeting their obligations and requirements under the Code of Practice.

Description

During the 1990s, guided by extensive public consultation, Alberta Environment reviewed water management policies and legislation and a comprehensive new statute, the Water Act, was enacted. Throughout the review process, Albertans made it clear that government needed to ensure sustainable water management and a healthy aquatic environment. The government agreed that effective and efficient water management planning is essential and made a commitment to develop a document to guide such planning, called The Framework far Water Management Planning. A major component of the Framework and a requirement of the Water Act is the Strategy far the Protection of the Aquatic Environment. The Strategy details the government's commitment to maintaining, restoring or enhancing the condition of the aquatic environment. Both the Framework and Strategy are presented in this document.

Description

The objective of this report is to determine whether the ecological effects of treated bleached kraft pulp mill effluent on aquatic invertebrates vary with water temperature. To address this objective, we initially summarized existing studies that evaluated the interactive effects of water temperature on the toxicity of a variety of compounds to aquatic invertebrates. This review indicated that there is a moderately large amount of information indicating that toxic effects of contaminants or other physicochemical stressors can vary with water temperature. These interactive effects between contaminant concentrations and water temperature raise the issue of whether toxic effects of pulp mill effluents that are typically evaluated at 15oC to 20oC, are representative of those at lower temperatures. This is relevant to rivers receiving pulp mill effluent in Alberta, which have lowest dilution capacity in winter, when water temperatures are near 0oC for five months or more. Our review of...

Description

Groundwater is an important natural resource in Alberta. Many farmers and small towns rely on wells to provide drinking water for both domestic and livestock use. Groundwater, however, is vulnerable to contamination from activities around wells and sometimes activities on the land. Groundwater is water that occupies the pore spaces in soil and rocks. It originates as precipitation that moves down through the soil and can be stored in aquifers.

Description

The purpose of the Lesser Slave Lake regulation report is to provide information to the area residents on the background leading to the regulation of water levels and on the effects this regulation has on the Lesser Slave Lake water levels. Impacts of the regulated water levels on agriculture, recreation, fisheries and municipal water supply are presented. The analyses are based on simulated water levels from 1916 to 1992 with the regulation project being in place and are compared to the water levels which existed under the natural lake outlet conditions.

Description

This report summarizes the results of the effluent sampling survey conducted at the Canadian Salt Company Ltd. plant at Lindbergh, Alberta from July 22 to July 25, 1975. The survey was part of the industrial monitoring program of the Water Quality Control Branch, Pollution Control Division. The sampling survey consisted of identification of all effluent sources, composite sampling of these streams over 3 days, as well as grab sampling of Moosehills Creek upstream of the plant and the raw water intake from the North Saskatchewan River.
