A recent study has shown that wastewater carries some unnatural additives—pollutants that may also be present in drinking water. Researchers at the Water Technology Center in Karlsruhe, Germany, found artificial sweeteners in water even after it had gone through sewage treatment. And these artificial sweeteners could be finding their way into drinking water.
This most recent study showed that the sweeteners are present in rivers and streams that receive water from sewage treatment plants. Additionally, water was tested after going through two different kinds of treatment: conventional wastewater treatment and advanced wastewater treatment by soil aquifer. The artificial sweeteners were found in the water after both treatment methods, suggesting that even the more advanced method is not sufficient in removing these pollutants.
