Description

This guide was developed to support schools and daycares when they undertake an assessment of lead and copper in drinking water in their facilities. It provides details on how to conduct an assessment of potential lead and copper, how to interpret the results when lead and copper levels exceed Health Canada's maximum acceptable concentration, and how to access support from Alberta Health Services throughout the assessment process.

Description

Cu deficiencies exist across the Canadian prairies in particular as well as south into the adjoining American states. Crop yield and quality losses in Alberta alone in both wheat and barley has run into tens of millions of dollars annually. Copper deficiency is a simple problem that can be corrected in most instances with a single application of granular copper-based fertilizer. The effects of this single application can last for up to 10 years or more. Foliar applications of copper fertilizer have to be applied annually to cereal crops growing on copper deficient land. Thousands of provincial producers from Fort Vermillion to Milk River have now seen modest to spectacular yield and quality gains from copper applications on their wheat and barley crops.

Description

This document contains the relevant toxicological information and other literature used to develop a water quality guideline that protects freshwater aquatic life against copper toxicity. Its derivation follows the Protocol to Develop Alberta Water Quality Guidelines for Protection of Freshwater Aquatic Life (Alberta Environmental Protection 1996). Copper is an essential compound for plants and animals in small quantities. However, copper becomes toxic when biological requirements are exceeded. Copper is widely distributed in environmental media because it is a naturally occurring element. Compared to natural emissions, emissions of copper from human activities are substantial. Most copper released from human activities comes from disposal of coal ash residue and spreading of municipal and industrial wastes on land.
