Water quality is increasingly becoming a focus of interest from diverse stakeholders. Whether for protection of aquatic species or for human consumption, a reliable understanding of the potential for exposure in both surface and groundwater is essential. Waterborne’s experience in being able to understand and model the fate and transport of chemicals in surface water provides reliable estimates of potential exposure. Regulatory models for surface water such as VVWM, EXAMS, AGRO, TOXSWA are utilized to best represent these environmental conditions.
Geographic Information Systems (GIS) have long been used in combination with specialized models to simulate the fate and transport of chemicals and other constituents in watersheds. Incorporating the entire upstream land area in an exposure assessment is an important component in ensuring water quality for years to come.
Groundwater represents a different environmental compartment for protection. Factors such as soil, weather and chemical properties influence the potential for movement to groundwater. Often groundwater modeling is paired with prospective or retrospective monitoring for comparison or validation. Exposure models using PRZM, PEARL, or MACRO are often applied in regulatory settings, however other models can be applied.
