Description

The objective of the sampling program initiated by AENV in July 2002 was to scope out the degree of spatial variability in Wabamun Lake water quality. Eight other lakes were also sampled to allow comparisons of the intra- and inter-lake variability in water quality. This document provides a compilation of the data and highlights the major findings

In 2002 Alberta Environment (AENV) initiated several studies (including this one) in response to complaints about murky water in the lake near the TransAlta Utilities Corporation (TAU) ash lagoon... More ≫

Description

In 2002 Alberta Environment (AENV) initiated several studies (including this one) in response to complaints about murky water in the lake near the TransAlta Utilities Corporation (TAU) ash lagoon outfall and in support of an investigation on fish mortality. The specific objectives of this study were to document surficial sediment quality of Wabamun Lake with respect to metals and trace organics and to compare results with those from other lakes.

Description

This report serves three main purposes. Firstly, it provides a refined representation of the sensitivity of Alberta lakes to acidifying atmospheric deposition. Secondly, it compiles data from a number of different surveys of northern lakes; spatial and temporal trends for these potentially sensitive lakes are described. Thirdly, this report documents and evaluates some of the chemical analyses used, providing a foundation for future work.
