Effluent Toxicity Testing Services

Introduction

We perform the full range of routine whole effluent toxicity (WET) testing services on effluents, storm water runoff, ambient and receiving waters to support National Pollutant Discharge Elimination System (NPDES) compliance. We also provide marine and freshwater sediment toxicity testing for a variety of monitoring programs, including ambient, agricultural, and sediment quality objectives (SQO).

Each year, we conduct thousands of bioassay procedures on wet and dry weather discharges, point and non-point source discharges, and soils and sediments. We support a wide variety of clients and projects such as NPDES compliance testing services and other types of environmental compliance monitoring, best management practice (BMP) assessment, site-specific water quality criteria development and negotiation, and total maximum daily load (TMDL) support. We also have expertise in method review and providing regulatory comment on the appropriate use and application of toxicity methods and data. We currently conduct programs for a variety of clients in commercial, federal, and municipal sectors across international geography.
