I have been involved with wastewater research for several years developing new disinfection methods and pollutant removal technologies from the effluent before it is released to the surface water. From the treatment plant supervisor's perspective, the only thing about wastewater treatment that matters is meeting the plant's National Pollutant Discharge Elimination system (NPDES) permit requirements. However, I am now looking beyond the NPDES permit and local geographical boundaries and trying to understand the impact of wastewater discharge thousands of miles away on the oceanic ecosystem, in particular on planktons. I am not a marine toxicologist. So, I am looking for your help in identifying the chemicals with the potential or known toxicity for planktons. Planktons, being on the bottom of the food chain can cause major disruption in the whole oceanic ecosystem if eliminated from the system. PCBs and some sunscreen products have been found to negatively impact the plankton population. Can you suggest any potentially toxic chemicals known to cause damage to planktons that might be present in the wastewater? If you can provide specific names or a class of chemicals, it will be really helpful. Your feedback and help are greatly appreciated.

Thank you,
