"PITT MEADOWS, British Columbia – On an early spring morning the Pitt River flows so calmly that the peaks of the Coast Range seem to pause to admire themselves in its glassy waters.

Zwiernik’s team monitored 60 active nests not only in the nine-block residential area surrounding the former Velsicol plant site but also 15 kilometers downstream. As was the case with the first batch of results, American robins eggs collected contained DDx levels far above those found to induce death in laboratory settings."
