We all need water for various purposes – for drinking, bathing, washing, irrigation etc. Amongst all, the drinking water should be safe and contamination free for a healthy living. There are various types of water tests which apply stringent criteria to ensure microbial, mineral and chemical safety of drinking water. A microbial or bacteriological test indicates presence of any pathogenic or disease-causing bacteria in the drinking water. EPA has designated testing of coliform bacteria as a standard for determination of safety of using water as these bacteria are simple to identify and are much abundant. The Drinking water test kit is made to check for presence of various coliform bacteria & nitrates. Suck kits are quite accurate as all testing material - including sampling bottles are often sterilized to prevent external contamination of samples. A mineral analysis on the other hand provides an estimate of the extent of mineral impurities in the water. Many industrial-waste chemicals can also contaminate a water supply and impair its usability and/or create a health hazard, for instance, petroleum products, industrial chemicals, agricultural pesticides, heavy metals like lead so and so forth. So, water must be checked periodically.
