This course will introduce you to the components of a 'typical' water quality field test kit, and get you started on how to use the equipment. Included are: basic information on water quality, interactive e-learning modules, quizzes and links to supplementary resources to help you test the quality of drinking water under field conditions. This course was designed for humanitarian and development workers and community health workers who do not have experience with water quality testing. You may not have access to laboratory equipment or services, but do have access to a portable test kit, or you just want to learn about water quality testing. While this course won’t allow you to become an expert, it will help you get familiar with water quality testing and with your kit!
