What are the two types of groundwater?
Groundwater is found in two zones. The unsaturated zone, immediately below the land surface, contains water and air in the open spaces, or pores. The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone.
What are the four types of groundwater?
Types of Geological Formations of Groundwater
- Aquifer.
- Aquitard.
- Aquiclude.
- Aquifuge.
Why is groundwater not good?
Groundwater may contain disease-causing microorganisms which can cause illness. Some groundwater supplies in Victoria have been found to contain high levels of chemical contaminants, such as arsenic, which can cause illness in people who drink the water.
What is the groundwater?
Ground water is water underground in saturated zones beneath the land surface. Contrary to popular belief, ground water does not form underground “rivers.” It fills the pores and fractures in underground materials such as sand, gravel, and other rock.
Is groundwater freshwater or saltwater?
Of the remaining 1 percent, almost all of it — about 96 percent — is groundwater, according to the National Oceanic and Atmospheric Administration (NOAA). The rest of our freshwater is found at the surface in streams, lakes, rivers and wetlands.
Which is not example of groundwater?
The correct answer is OPTION 1: Water flowing in rivers. It acts like water in a sponge, filling the pores and crevices in subterranean materials like sand, gravel, and other rock.
What are the negative effects of groundwater depletion?
Some of the negative effects of ground-water depletion include increased pumping costs, deterioration of water quality, reduction of water in streams and lakes, or land subsidence. Such effects, while variable, happen to some degree with any ground-water use.
What are the advantages of groundwater?
The advantages of ground water are:
- i. Ground water does not evaporate.
- ii. It is helpful in maintaining the water levels of wells.
- iii. Ground water provides moisture to large amount of vegetation.
- iv. There is relatively few chances of contamination of ground water by human and animal waste.
What is groundwater resources?
The groundwater resource is a sustainable water resource belonging to the earth’s water cycle, which flows thanks to the natural energy provided by the sun.

What does groundwater mean in California Court?
Groundwater and the Courts. Percolating groundwater is often defined as water moving through the soil by gravity along the path of least resistance. In California, the term covers all groundwater that is not flowing in a known and defined channel.
Is there a universal law governing groundwater management in California?
But in California, which does not have a statewide groundwater management program, the only truly universal law governing pumping is the state constitutional mandate that water not be wasted or put to a non-beneficial use . Defining groundwater rights in the West has never been easy.
What is the difference between groundwater and surface water rights?
In the past, the guiding principle, in contrast with the centralized state-controlled surface water rights, is that with groundwater, geology is varied and can be complex and location-specific, so decision-making is best left to local officials.
What is the Sustainable Groundwater Management Act?
The Sustainable Groundwater Management Act (SGMA) was carried by Sen. Fran Pavley, D-Agoura Hills and Assemblyman Roger Dickinson, D-Sacramento. It requires land use plans to consider groundwater sustainability plans and to assess the impact of land use on groundwater.
