Publisher Summary
In a landscape dominated and modified by human activity, it is not be surprising that the water one drink's contains both chemical and biological pollutants. Environmental science evaluates how humans use the earth's natural resources, appraises the repercussions that occur as the result of this use, and evaluates how to mitigate these impacts. Because water that exists at and below the earth's surface is in contact with soil and rock, some mineral or organic matter is dissolved in it. Based on the natural properties of water (H2O) and the properties of each chemical element and mineral combination, the actual occurrence and concentration of an element in water can vary widely. Another crucial chemical property of water is its relative acidity or alkalinity. This chemical characteristic has a direct influence on the concentration of minor elements and trace elements. Many of the compounds found in natural water are the result of biosynthesis and biodegradation. As a result, natural water can contain a wide range of organic compounds. The chemistry of natural water is highly dependent on its geologic and hydrologic origins, as well as its biological contributions. The imparted chemical characteristics to natural water can be highly valued or a potential threat to public health. The federal government essentially issued a license to allow water resources to be polluted up to an acceptable level. As a natural consequence of setting water quality criteria, specific definitions for the terms contamination and pollution were developed.
