Water analysis is performed by trained professionals to determine the safety and purity of drinking water, or to assess contamination levels from pollution or other problems. It can also be used to assist in reversing such problems, or to measure osmosis of outside chemicals into municipal water supplies for health reasons. The information gathered from water analysis may be used for educational (microbiology, for instance) or industrial purposes as well. Test kits use colorimeters, electrochemical markers, ion selective filters, pH meters, turbidimeters and chemical strips, among other tools, to check for reagents such as chlorine, environmental pollutants, oxygen osmosis and water quality. Purification of wastewater requires equipment such as filters and boilers, as well as constant analysis to ensure that such measures are working correctly.
