Apart from the drought, California also has another threat to its water supply: toxic wastewater. The Sacramento Bee reported that the oil industry’s habit of dumping wastewater is a major contributor to this issue. According to some recently revealed investigations and documents, state regulators have allowed over 2,400 illegal injection wells for oil production or wastewater disposal into protected Aquifers of California. Some of these stores hold water clean enough for human consumption or crop irrigation.
Several of those wells were shut down in the previous summer, but many oil companies are still dumping wastewater into supposedly protected underground resources, as admitted by state officials. This poses a significant risk to the water supply of California and to its citizens. Aside from this, there have also been reports of arsenic and nitrates found in the state’s waters.
