STATISTICAL ANALYSIS OF NEWFOUNDLAND DRINKING WATER SOURCES CONTAINING ARSENIC
ABSTRACT Arsenic (As) is a toxic element that is released to the environment by natural processes and anthropogenic activities. Canada and the United States recently lowered their recommended maximum acceptable concentration for As in drinking water to 10 μg/l. However, As contents exceeding this le...
