EPA Releases User-Friendly Pesticide Concentration Calculator

The Environmental Protection Agency (EPA) has 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.

Key Improvements: Faster, Easier and More Comprehensive

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

Automated Features Enhance Accuracy

The updated calculator integrates a number of previously distinct processes into one smooth operation. It no longer requires extra models since it now automatically computes parameters like pesticide spray drift. 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.

Promoting Transparency and Collaboration

The purpose of making this calculator available to the public is to increase the transparency of EPA's risk assessment procedures. This tool can be used by stakeholders to provide input on submissions to the Agency, encouraging collaboration and informed decision-making.

This update follows a previous update from April 2023, which standardised scenarios for evaluations of ecological and drinking water risks. To ensure the efficacy of the model, EPA will continue to update it as needed.
