Where does my drinking water come from?

 The drinking water that is supplied to our homes comes from either surface water or groundwater. Surface water collects in streams, rivers, lakes, and reservoirs. Groundwater is water located below the ground where it collects in pores and spaces within rocks and in underground aquifers. We obtain groundwater by drilling wells and pumping it to the surface.

Public water systems provide water from surface and groundwater for public use. Water treatment systems are either government or privately-held facilities. Surface water systems withdraw water from the source, treat it, and deliver it to our homes. Groundwater systems also withdraw and deliver water, but they do not always treat it.


A private well uses groundwater as its water source. Owners of private wells and other individual water systems are responsible for ensuring that their water is safe from contaminants.
