  • Emerging Organic Contaminants

    Emerging Organic Contaminants (EOCs) have been defined as synthetic or naturally-occurring chemicals or any microorganisms not commonly monitored in the environment, but which have the potential to enter the environment and cause known or suspected adverse ecological and (or) human health effects (Stewart et al. 2016). Municipal wastewater treatment plant (WWTP) effluent is recognised as a major source of EOCs into the environment. The Nelson Regional Sewerage Business Unit (NRSBU) contracted the Cawthron Institute and Northcott Research Consultants Limited (by subcontract) to analyse a suite of EOCs in the effluent from the Bell Island WWTP.
