Water quality measuring equipmentEdit
Water-quality testing kit: IDEXX (1 Idexx Drive Westbrook Maine, 04092 Tel: 207/856-0300) manufactures and sells Colilert, a 24-hour EPA-approved coliform and E. coli test that can be used in the field. Microbiologist Bob Metcalf of Solar Cookers International and others have used this simple, light-weight kit to test the drinking water brought from home by participants in solar cooking workshops. Bob has written a guide to using the Colilert test in the field which describes how to test effectively in developing countries without slavishly following the manufacturer's somewhat over-cautious recommendations.
Dr. Bob Metcalf has created the Portable Microbiology Laboratory, which contains everything needed for water quality testing in the field.
