The quality of the water we drink and use for personal care is very important to our health. From the well to the faucet, water comes into contact with many different materials, chemicals, and technologies. This is where planners, tradespeople, building owners, and occupants can make a difference. This course module covers the environmentally and health-conscious use of laundry detergent and cleaning agents, as well as the pros and cons of water-saving technologies, including the use of rainwater and graywater.
