Emerging Contaminants
Science Center Objects
Emerging contaminants, or contaminants of emerging concern, can refer to many different kinds of chemicals, including medicines, personal care or household cleaning products, lawn care and agricultural products, among others. These chemicals make it into our Nation's lakes and rivers and have a detrimental affect on fish and other aquatic species. That have also been shown to bioaccumulate up the food web - putting even non-aquatic species at risk when they eat contaminated fish. The USGS monitors and assesses these dangerous chemicals from their source all the way through the food web.
BACKGROUND
Since the 1990s studies around the country have investigated how a wide range of chemical compounds, industrial pollutants, and human by-products have been making it into our Nation's waterways. Traditionally, most people were not overly concerned about this because the old mantra used to be "dilution is the solution to pollution" However, this is far from true. After the contaminants make it into the rivers and streams, tests show that there are measurable quantities of these contaminants within the water, itself, as well as in the under-water sediments, the nearby aquatic insects, migratory fish that eat the insects, and even predatory wildlife that consume all these different organisms.

Contaminants of emerging concern enter the environment every day. To understand where these chemicals come from, we just need to think about our modern lifestyle. People use chemical-based products each day. These chemicals remain in wastewater and beyond because treatment plants weren't designed to take out these chemicals. Similarly, industrial processes that have their own treatment processes don’t remove all these chemicals, either. Eventually, they end up in the Nation’s lakes and rivers. So these chemicals are getting into the environment and we're concerned about the effects they might be having on organisms, including humans. After all, different contaminants have been detected in drinking water supplies and their risk to our health is still uncertain.

Hormones and pharmaceuticals in groundwater used as a source of drinking water across the United States
This is the first large-scale, systematic assessment of hormone and pharmaceutical occurrence in groundwater used for drinking across the United States. Samples from 1091 sites in Principal Aquifers representing 60% of the volume pumped for drinking-water supply had final data for 21 hormones and 103 pharmaceuticals. At least one compound was...

Wastewater indicators, hormones, sterols, antibiotics, and pharmaceuticals in soil at an agricultural field irrigated with domestic septage, central Minnesota, September 2014
Treated domestic septage can be used to irrigate agricultural fields as a disposal method or as a means to reuse water. Because traditional on-site treatment systems are not designed to remove wastewater indicators, hormones, sterols, antibiotics, and pharmaceuticals, land application of septage potentially results in soil contamination. Soils...
