  • Selective Serotonin Reuptake Inhibitors and β‐blocker Transformation Products May Not Pose a Significant Risk of Toxicity to Aquatic Organisms in Wastewater Effluent‐Dominated Receiving Waters

    A probabilistic ecological risk assessment was conducted for the transformation products (TPs) of three β‐blockers (atenolol, metoprolol, and propranolol) and five selective serotonin re‐uptake inhibitors (SSRIs; citalopram, fluoxetine, fluvoxamine, paroxetine, and sertraline) to assess potential threats to aquatic organisms in effluent‐dominated surface waters. To this end, the ...

    The US Geological Service and Environmental Protection Agency have been monitoring the increasing levels of persistent organic pollutants (POPs) in freshwater streams, aquifers, and off-shore coastal waters for the past decade, with the primary identified chemicals being residuals from pharmaceuticals, and petroleum-based fertilizers, herbicides, and pesticides (Pyrines and Pyroids). This ...


  • Proposed plans for UCMR Program

    At an April 2010 stakeholder’s meeting, the EPA discussed proposed plans for the third phase of the Unregulated Contaminant Monitoring Regulation (UCMR) program. If approved, approximately 4,800 public water utilities will be required to monitor up to 30 contaminants starting in 2013. The second phase of UCMR (UCMR 2) sampling, which began in 2008, concludes at the end of this year. UCMR 2 ...


  • Chemicals in reverse osmosis-treated wastewater: occurrence, health risk, and contribution to residual dissolved organic carbon

    The quality and safety of reverse osmosis (RO)-treated secondary wastewater (WW), for indirect potable re-use, was assessed using a dataset of 375 chemicals measured in RO-treated WW. A screening health risk assessment indicated that four N-nitrosamines were of potential concern, although median concentrations of these chemicals were always below health values. The most frequently detected ...
