Pipe Dreams: Tapping into the Health Information in Our Sewers
The emerging field of sewage chemical-information mining is taking advantage of a readily available yet underappreciated resource: the untreated waste flowing under our feet and the biosolids remaining after treatment. It turns out that sewage and sewage sludge hold a wealth of data on chemical consumption and exposure, and potentially even the health status of whole communities.EHP

Most chemicals that people are exposed to via consumer products are ultimately washed off or excreted; they are collected in municipal sewers and sent to wastewater treatment plants (WWTPs). Fat-soluble chemicals—i.e., those that can accumulate in the human body— tend to be the ones that resist treatment.Source: Courtesy Arizona State University
Substances that withstand treatment can find their way into fertilizer derived from sewage sludge. This popular soil amendment for agricultural fields thus represents a potential route for anthropogenic chemicals to enter the food supply.© Justin Kase zsixz/Alamy
Surveys of sewage sludge have revealed varying concentrations of dozens of anthropogenic chemicals, including a) compounds used in pharmaceuticals and personal care products, b) surfactants, c) perfluorinated compounds, and ...
