Groundwater vs surface water

The surface water gets easily contaminated and has plenty of pathogens. In contrast, the groundwater is pure, and the presence of pathogens is almost nil. The constant exposure to sunlight heats up the surface water which rises the temperature. Whereas the groundwater remains covered and thus has a constant temperature.

Ponds, lakes, reservoirs, sinks, etc. in the basin, which prevent or delay runoff from continuing downstream. When water "runs off" the land surface, that’s runoff! Due to gravity, the water you wash your car with runs down the driveway as you work, and rain runs downhill. Runoff is an important component of the water cycle.This diagram uses a "cylinder and pipe" layout to show the source (surface water or groundwater) of the Nation's freshwater and for what purposes the water was used in 2015. The data are broken out for each category of use by surface water and groundwater as the source. Data are rounded and are reported in million gallons per day .The Water Quality Control Commission (WQCC) addresses Colorado’s standards for groundwater in Regulation 41, 42, and 43 (listed on the WQCC regulations page). The Water Quality Control Division regulates the discharge of pollutants into the state's surface and groundwater under the provisions of the Colorado Water Quality Control Act of 1974. While groundwater generally has a higher mineral content than surface water, it requires less treatment than surface water. To help ensure that customers only receive safe, high quality water, chlorine is added to groundwater to prevent growth of bacteria in the pipes and tanks of the water distribution system.However, progress has slowed with pollution in 58% of surface water since 2016. In addition, only 42% of surface water bodies and 77% of groundwater are rated …Groundwater, under most conditions, is safer and more reliable for use than surface water.

In many places wells provide a reliable and ample supply of water for home uses, irrigation, and industries. Where surface water is scarce, such as in deserts, people couldn't survive and thrive without groundwater, and people use wells to get at underground water.Groundwater is a part of the natural water cycle (check out our interactive water cycle diagram). Some part of the precipitation that lands on the ground surface infiltrates into the subsurface. The part that continues downward through the soil until it reaches rock material that is saturated is groundwater recharge.

Groundwater pumping can alter how water moves between an aquifer and a stream, lake, or wetland by either intercepting groundwater flow that discharges into the surface-water body under natural conditions, or by increasing the rate of water movement from the surface-water body into an aquifer.
