Beatrice Silver was in the middle of cataloguing the health impacts caused by industrial pollution in her community with her neighbour, Clarence Williams, when Williams’ health declined and he passed away. Williams was in his late 50s, and Silver says his death is connected to the job he previously held at Westlake Pipe and Fitting facility, which makes polyvinyl chloride, or PVC pipes. The factory is located in the middle of Upper Sumas 6 reserve.
