In 2007, about 390 million kilograms (430,000 tons) of pesticides, including herbicides, insecticides, and fungicides, were used in the United States. Pesticides released into the environment for agricultural and nonagricultural purposes can contaminate surface water and groundwater, which are critical sources of drinking water.The various forms of surface water are lakes, rivers, streams, ponds, etc. The surface water lacks in minerals. Ground water is the water located under the ground in a subsurface layer of rocks or soils. The ground water is very rich in minerals. The ground water is generally located in aquifers and can be taken out by drilling deep wells.Groundwater and Humanity. Groundwater is a vital water supply for humanity. Groundwater provides drinking water entirely or in part for as much as 50% of the global population and accounts for 43% of all of water used for irrigation. Worldwide, 2.5 billion people depend solely on groundwater resources to satisfy their basic daily water needs.Water is an essential part of our lives. We need water for the smooth functioning of our lives. However, there isn’t much water left on the planet which is capable of consuming. The sources of water are also running out to a great extent. They are oceans, surface, groundwater and ice caps and glacial melting water.

Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.Groundwater and Humanity.

Jun 6, 2018 · Following rainfall, variations in groundwater turbidity may be an indicator of surface contamination. Color. Can be caused by decaying leaves, plants, organic matter, copper, iron, and manganese, which may be objectionable. Indicative of large amounts of organic chemicals, inadequate treatment, and high disinfection demand. 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.

The quality of surface water and groundwater is a sensitive issue as far as health is concerned. Contamination of these resources should be prevented, controlled and reduced. Heavy metal contamination and contamination due to potassium ions, nitrates, phosphate, chloride and organic solvents need to be removed.If the water cycle were to stop, lakes, rivers and groundwater sources would dry up, glaciers would disappear and precipitation would stop falling.
