more and more irrigation water will be needed to meet increasing demands for food for growing populations. This will require intensive management and international cooperation. Since almost all liquid fresh water on the planet occurs underground‚ groundwater will be used more and more and‚ hence‚ must be protected against depletion and contamination‚ especially from non-point sources like intensive agriculture. Such a holistic approach requires not only supply management‚ but also demand management

The fibrous root structure of those native plants‚ acted as an effective filter with their high water-holding capacity. Some rainwater was held by the roots and some rainwater leached downwards through the soil carrying the dissolved salts. Groundwater transpired back into the air through the leaves of the native plants. As Europeans introduced traditional

Groundwater contamination is the degradation of natural water quality as a result of human activities‚ and pollution occurs when contaminant concentration levels restrict the potential use of groundwater.

Volatile organic chemicals (VOCs) contaminate 90% of the U.S. aquifers‚ but 2% of samples had unsafe VOC levels. The US found that ⅓of the 26k industrial waste ponds didn’t have liners to prevent toxic liquid wastes from seeping into aquifers. The EPA had completed the cleanup of 297k of the 436k underground

Summary: Water pollution remains one of the most visible and persistent signs of our impact on the natural world. Cleanup of some older pollutants has been offset by new contaminants that threaten freshwater ecosystems and foul our drinking water. The sight and smell of grossly polluted waterways provided some of the original impetus to the environmental movement in the 1970s. Nearly a century before that‚ the dangers of polluted water to human health drove what became known as the "sanitary
