The presence of hormones in drinking water is a human health concern with several being routinely monitored as part of the U.S. Environmental Protection Agency (EPA) Unregulated Contaminant Monitoring Rule 3 (UCMR3). Due to the widespread use of hormone pharmaceuticals, these often end up in the sewage system as a result of excretion and disposal of unwanted quantities. To monitor the levels of the most common hormones in drinking water, EPA method 539 was developed and this is the basis for the work presented here. Seven hor­mones were concentrated using an automated solid phase extraction (SPE) system containing high surface area reversed-phase (HRPHS) cartridges, followed by liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) with time selected-reaction monitoring (TSRM) for detection and quantification.
