RANCHO CORDOVA, Calif. (AP) - California experts are going to take one of the closest looks yet at the safety of watering food crops with oilfield wastewater.
A Central California regional water board said Tuesday it has pulled together state officials, academics and others on the little-studied issue.
Experts say at least five oilfields in the state are now passing along their leftover production fluid to water districts for irrigation, for recharging underground water supplies, and other uses, experts said.
Hydraulic fracturing and other oilfield production generate nearly 2 billion barrels of wastewater a year in the San Joaquin Valley alone.
Increasing number of almond and pistachio growers and other farmers are using the oilfield wastewater to irrigate their food crops.
