The scientist should test and study target area in order to identify groundwater. The observed landscape can provide information about the occurrence of shallow groundwater. For example, groundwater is more often found under valleys than under hills. Another indicator of groundwater are “waterloving” plants. The presence of groundwater is also under the areas where water is at the surface such as springs or seeps.
Features of the water that can be observed are:
Composition of water-depends on the nature of the soil, so for example if water is circulating in a sandy soil it is acidic and has a few minerals,
Temperature of the water-it varies with season (surface water) or it is usually constant (groundwater),
Turbidity- in surface water, level variables while in ground water is low
Color of water-depends on its composition.
