Having safe drinking water is a human need and right for every man, woman and child. People need clean water to maintain their health and dignity. Having better water is essential in breaking the cycle of poverty since it improves peoples health ,strength to work.However, declining water quality threatens the gains made over the past twenty years to improve access to drinking water. From 1990 to 2011, global efforts have helped 2.1 billion people gain access to improved drinking water, but not all of these new sources are necessarily safe.The quality of our global freshwater supplies is under increased threat of contamination. While water contains natural contaminants, it is becoming more and more polluted by human activities, such as open defecation, inadequate waste water management, dumping of garbage, poor agricultural practices, and chemical spills at industrial sites.Chemical contamination of drinking water both naturally occurring and from pollution is a very serious problem.Water quality testing is a tool that can be used to help identify safe drinking water. Water testing plays an important role in verifying the safety of drinking water, investigating disease.
