Topics include water quality issues, water quality parameters, water treatment options, carbon filters, types of purifications systems, reverse osmosis, sterilization, water conditioning.
Municipally treated water is usually low in biological contaminants because of chlorination, but it is not well-screened for industrial and hazardous waste. The chlorine with which almost all municipal water is treated reacts with naturally occurring organic materials, creating harmful trihalomethanes. This is in addition to the chlorine itself which is a microbial poison. And yet health-supporting household water is attainable and affordable, as this course amply illustrates.
