Pine beetle may affect drinking water, experts say

A major attack of the mountain pine beetle on a forest in Alberta could threaten more than just the trees.

It could also lead to water quality issues that may create headaches when it comes to treating drinking water downstream, according to an expert at the University of Alberta.

Healthy trees, especially older ones, use a "huge" amount of water from early spring through October, according to Uldis Silins, a professor in the department of renewable resources at the University of Alberta.
