The data may suggest that growing lowland rice during the wet season could reduce the amount of nitrate leached to the shallow aquifer.
These values, however, do not measure the other non-timber benefits of the forest, only its contribution to aquifer recharge.
Irrigators can also get ground water or contingent water rights, which can be used to fill dams or recharge aquifers.
Under such conditions, nitrate can be leached and can contaminate the shallow aquifer which is also a source of drinking water.
The topography and chaotic terrain may favor a hydrothermal aquifer as the original setting where hematite formed.
An important example is the extraction (appropriation) of resource units from a renewable resource stock such as fish, rangelands, groundwater aquifers, or forests.
Geothermometry and chemical and isotopic compositions can be used to assess changes in aquifer status during production.
Let us assume that over a semiperiod the particles travel a small distance compared with the size of the aquifer.
