Rivers are surface water sources that flow towards the ocean. They are generally larger than creeks and are predominantly fresh water sources with a range of contaminants. The contaminants in a river will depend on the material the river flows through as well as what lives in and along its banks. The two main contaminants in river water are suspended solids (which will vary in concentration during the year) and microbiological contamination. A river will become brackish as it approaches the ocean, so the treatment technologies required will depend on how far from the ocean the river water is drawn. Major cities and extractive industries are commonly located on rivers, so industrial pollution can also be a contaminant of concern. […]
