The Environmental Protection Agency (EPA) announced the release of a significantly improved Pesticide in Water Calculator. This updated tool makes it easier to estimate pesticide concentrations in water bodies, which helps with risk evaluations for both ecological and human health.

Faster, Easier, More Comprehensive

Faster processing rates and an intuitive interface of the new calculator enable speedier and more effective analysis. One important feature is the ability to conduct numerous pesticide simulations at once, which eliminates a laborious manual process that was previously required.

Automated Features Enhance Accuracy

The updated calculator combines a number of formerly distinct phases into a smooth operation. It no longer requires extra models since it now computes parameters like pesticide spray drift automatically. In addition, users may automatically include all pertinent water bodies in risk evaluations and take into consideration how the weather affects the application of pesticides.

The purpose of making this calculator available to the public is to improve the openness of the EPA’s risk assessment procedures. This tool may be used by stakeholders to provide input on submissions to the Agency, encouraging cooperation and well-informed decision-making.

The most recent update comes after a previous one from April 2023 that standardized scenarios for evaluations of ecological and drinking water risks. To ensure the efficacy of the model, the EPA will keep updating it as needed.
