The Kern County Housing Authority operates a farm labor housing center near Shafter, California. The housing center only operates six months of the year, when transient laborers work the nearby farms. The well supplying water for the North Shafter Farm Labor Center began experiencing nitrate contamination several years ago, causing the authority to purchase bottled water for the residents. To reduce the expense associated with bottled water, the authority obtained a grant to construct an ion exchange nitrate removal plant for the center. The treatment plant, which began operation in early April 1994, produces 480 gpm (30 L/s) of water with nitrate reduced from 62 mg/L to 30 mg/L.
