Groundwater pollution in Central Valley, California
Aerial view of Central Valley waterways.
Contaminated groundwater in the Central Valley of California is a growing problem due to contamination and overuse.[1] This problem is compounded by the overdrafting of underground aquifers.[1]
Currently, nitrates are the most abundant pollutants in the Central Valley due to the copious amounts of agricultural runoff from the farms.[2] The concentration of naturally occurring arsenic is also an issue.[3] This is a public health concern as groundwater is often the primary water source in the region.[1]
Near-term solutions to reduce pollution and overuse are often costly and hard to implement in a timely manner.[citation needed]
