Physical, chemical, and biological methods have been used to remediate arsenic contaminated water.[181] Bioremediation is claimed to be cost-effective and environmentally friendly.[182] Bioremediation of floor water contaminated with arsenic aims to convert arsenite, the poisonous type of arsenic to humans, to arsenate. Arsenate (+5 oxidation state) is the dominant type https://www.xcritical.com/ of arsenic in floor water, whereas arsenite (+3 oxidation state) is the dominant form in hypoxic to anoxic environments. Many species of bacteria can remodel arsenite to arsenate in anoxic situations by using arsenite as an electron donor.[183] This is a helpful technique in ground water remediation. Another bioremediation technique is to use crops that accumulate arsenic of their tissues via phytoremediation but the disposal of contaminated plant material must be thought-about.

In polluted areas, uptake of the more toxic arsenite ion (found extra significantly in decreasing conditions) is in all probability going in poorly-drained soils.
The Occupational Safety and Health Administration has set the permissible exposure limit (PEL) to a time-weighted average (TWA) of 0.01 mg/m3 (0.01 ppb), and the National Institute for Occupational Safety and Health (NIOSH) has set the beneficial publicity limit (REL) to a 15-minute constant publicity of 0.002 mg/m3 (0.002 ppb).[193] The PEL for organic arsenic compounds is a TWA of zero.5 mg/m3.[194] (0.5 ppb). A few species of bacteria are in a position to make use of arsenic compounds as respiratory metabolites. Trace portions of arsenic may be an essential dietary factor in rats, hamsters, goats, chickens, and presumably other species.
