A source water assessment was conducted in April 2002. Well 1-McArthur Well is considered vulnerable to agricultural drainage and non-irrigated crops. The well is also vulnerable to agricultural/irrigation wells. Arsenic is detected in the water supply and is believed to be associated with runoff from orchards, electronics production wastes, and erosion of natural deposits. Fluoride is detected and linked to natural deposits and fertilizer/aluminum factory discharge.
