After sitting idle for 10 years the arsenic treatment plant won't be getting revamped. The state found clean water near the plant when they dug a well recently. This is the third installment in our series Contaminated, in which we explore the 300 California communities that lack access to clean drinking water.

Arsenic xide is obtained as a byproduct from dusts and residues produced during the treatment of other metal ores such as gold and copper. [25] The arsenic xide can be purified on site or sold to a refinery. [7] China is the world's leading producer of arsenic (25,000 tons in 2014) followed by Chile (10,000 tons) and Morocco (8,000 tons).

With respect to wild type, the profile of rpn4Δ after treatment with arsenic was the most dramatically altered, save for arr1Δ (Figure (Figure2 2 and Additional data files 11 and 12). These data suggest that arsenic modification of sulfhydryl groups on proteins leads to protein inactivation and therefore degradation via the 26S proteasome.
