Testing water filtration systems

Water is crucial to human life, but it can also be a killer.

Water contaminated with micro-organisms or chemicals, which is then used for drinking or cooking, is a leading cause of disease and death across the world. Poor facilities for the disposal of sewage and other waste water can quickly lead to the spread of dangerous diseases.
