Have you ever wondered how chemicals behave across a landscape, which areas are more vulnerable to leaching or runoff, and when to use advanced modeling in higher tier assessments? Using spatially distributed modeling, those questions and more can be answered by Waterborne’s experts and tailored to your project needs. 

We assess the fate of chemicals from the field-level to continental-scale and determine how these chemicals impact our waters. Our experts use geographic information systems (GIS) in combination with models such as SWAT, PRZM, RIVWQ, RICEWQ, and GeoPEARL to compute estimated environmental concentrations in groundwater and surface waters under different agronomic and weather conditions. Waterborne has modeled watersheds in the United Kingdom, United States, Japan, Australia, Brazil, and Europe. Spatially distributed models are an excellent tool to determine the impact of best management practices (BMPs) across the landscape. 

For consumer products Waterborne uses specialized models based on river networks. We host and enhance the iSTREEM model which uses a river network of over 200,000 miles to model in-river concentrations based on waste water treatment plant effluent from more than 10,000 wastewater treatment plants in the US alone. iSTREEM is available for the US, Canada, Japan, Mexico, and China. Whereas our SPatially EXplicit environmental routing and deposition model (SPEX) is designed to estimate emissions and model the fate of particles (such as microplastics) exiting point and non-point sources in the US and the EU. Our staff can help you select the best model for your solution.

Also, Waterborne staff is actively involved with the SETAC EMAG-Pest SDLM group. The goal is to establish a standard SDLM method to be used according to the FOCUS groundwater tiered approach (FOCUS, 2014, Sanco/13144/2010, version 3, 10 October 2014).
