Welcome to CoreFacts, where we're always short on time and big on science. I'm Brian Campbell. Today's question is …

How is water cleaned?

There are many different kinds of treatments depending on what contaminant is in the water. Biological contamination is usually treated by heat (boiling) or by filtration. Inorganic contaminants dissolved in the water can be removed by distillation or chemical exchange. Organic contamination has been treated by biological and chemical remediation, and new treatment methods are being tried every day.
