| environ. | groundwater endangering Threat to the quality and quantity of groundwater by activities related to the use of land. As some activities (e.g. landfill) present a particular risk of pollution, the closer an activity is to a well or borehole, the greater the risk of the pumped water being polluted. The type of soil, the geology, the rainfall and the amount of water pumped out of the ground must all be taken into consideration | utsette grunnvann for fare |
| environ. | groundwater extraction The process, deliberate or inadvertent, of extracting ground water from a source at a rate so in excess of the replenishment that the ground water level declines persistently, threatening exhaustion of the supply or at least a decline of pumping levels to uneconomic depths | grunnvannsuttak |
| environ. | groundwater pollution Contamination of any water found under the earth's surface by any leaching pollutants, such as inorganic compounds (chlorides, nitrates, heavy metals, etc.), synthetic organic chemicals (pesticides, fertilizers, etc.) and pathogens (bacteria, parasites, etc.) | grunnvannsforurensning |
| environ. | groundwater protection Precautionary actions, procedures or installations undertaken to prevent or reduce harm to the environmental integrity of fresh water found beneath the earth's surface, usually in aquifers, which supply wells and springs | grunnvannsvern |
| environ. | groundwater quality Groundwater accounts for over 95% of the earth's useable fresh-water resources; over half the world's population depends on groundwater for drinking-water supplies. This invisible resource is vulnerable to pollution and over-exploitation. Effective conservation of groundwater supplies requires the integration of land-use and water management | grunnvannskvalitet |
