Has pollution made drinking water unsafe?
Environmentalists warm that groundwater is badly polluted. Environmental writer Steve Coffel calls groundwater pollution the plague of the 1990s because almost everyone uses groundwater and will be adversaly affected if it becomes seriously polluted.
Groundwater is the water held beneath the earth in large pools and mineral formations. It is the largest available supply of drinkable water. Because groundwater collects at the lowest levels underground, pollutants that settle on the soil above ground eventually seep into it. Year after year they accumulate there. Some groundwater pollutants have been found in concentrations thousands of times greater than in surface water like lakes and rivers.
Those on the opposite side of the debate about water pollution contend that the water supply is safe. Researcher Kristine Napier, for example, argues that the public equates safe water with pure water and that the two are not the same. Napier points out that pure water has never existed in nature,only in laboratories. All natural water is contaminated by other ingredients. Whether it is safe to drink depends not so much on what is in it, but on how much of the contaminant is in it.
In addition, these people argue, water is tested much more thoroughly than in the past. Recent technology has allowed scientists to detect water pollutants at increasingly minute levels. When the scientists report their findings, the public becomes alarmed. But people have probably been drinking these small amounts of polluntants with their water for decades without ill effect.
