Drinking natural mineral water (coliform group) detection

BAIJIAN - a professional third-party testing and inspection platform that provides testing services for drinking natural mineral water (coliform bacte

Drinking natural mineral water is water that naturally gushes from deep underground or is collected through drilling, contains a certain amount of mineral salts, trace elements, or other components, is not contaminated in a certain area, and preventive measures are taken to avoid pollution; Under normal circumstances, its dynamic indicators such as chemical composition, flow rate, and water temperature are relatively stable within the natural cycle fluctuation range
