As oil and natural gas development expands in the MHA (Mandan, Hidatsa, and Arikara) Nation, current air and water quality needs to be studied and recorded, along with additional continued monitoring, to determine how the air and water quality have changed. There are currently no local existing air quality data for the MHA Nation communities. There were never any baseline studies done prior to the oil and natural gas development. There are currently nearly 1,000 active wells located on the reservation producing over 300,000 barrels of oil per day. There could be potentially another 2,400 additional wells in the future. It is very important to gain an accurate reading of air quality in the MHA Nation before natural gas drilling expands significantly.
