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...

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 level have been detected in many wells and some small surface water bodies in the eastern, central and western regions of Newfoundland.

The primary purpose of this paper is to obtain a better understanding of the factors contributing to the high levels of As in ground and surface water supplies in Newfoundland. Water sample data for the 52 sources were statistically analyzed to identify significant correlations among 32 different parameters. Principal component analysis revealed some differences from water sources in the eastern region of Newfoundland where the main geological formations were different than in the central and western Newfoundland regions.
