Where does water go once it flows down the sink drain? What about the water trickling down the street into storm drains? Or water discarded from industrial activities? Wastewater is “used water” that’s created by households, cities, and industry. It’s most commonly associated with sewage, but we can also talk about surface runoff and stormwater that flows from roadways into storm drains. In any case, wastewater and stormwater eventually end up in the environment. Because wastewater can come from many different sources, it can contain a variety of pollutants—soaps and personal care products, sanitary waste, pesticides and fertilizers, and fuel, to name a few. Industrial processes might produce wastewater laced with heavy metals or heated so hot that it harms living things nearby. On this page we’ll collect and organize resources on wastewater and how people can begin to investigate it.

Some places to startHere are some activities you might want to try when starting to research wastewater pollution. [notes:grid:getting-started-wastewater] Information on wastewater pollutionSewer systems and how people get exposed to wastewaterIn cities and towns in the US, you’ll mostly find two different kinds of sewer systems that collect and transport wastewater: combined sewer systems and separate sewer systems. Combined sewer systems collect both stormwater runoff from storm drains AND raw sewage from buildings and households. The stormwater and sanitary sewage are both directed in a single pipe to a wastewater treatment plant to be cleaned. When there are heavy rains, however, this increases the amount of stormwater flowing into the combined system. Not all the extra incoming water can be handled by the wastewater treatment plant, and so the rest is released directly into the environment as a Combined Sewer Overflow (CSO), raw sewage and all. In New York City, for example, about 60% of the city is served by a combined sewer system. Separate sewer systems have, as one might guess, separate pipes for stormwater and sanitary sewage. Many stormwater systems in the US are Municipal Separate Storm Sewer Systems (MS4) that have to follow regional and federal permit regulations to reduce water pollution. In most cases, though, the stormwater isn’t fully treated before it gets released into the environment. A separate sanitary sewer system transports raw sewage from households, businesses, and other buildings to a wastewater treatment plant. There, the sewage is treated and the cleaned water is released into the environment.
With any kind of sewer system, there’s the threat of exposing people to wastewater. Untreated or under-treated wastewater can make its way into waterbodies that people use for recreation, fishing, or drinking water. Pollutants can also become airborne when wastewater enters coastal areas. The wastewater might be legally released under a permit, it might be illegally dumped, or it might leak from broken pipes and other sewer system infrastructure. Wastewater pollutants
