Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 30 April 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 August 2029.

Abstract

Tiny particles such as microplastics, pathogens, and other contaminants are increasingly found in groundwater, raising concerns for drinking water quality and ecosystem health. Predicting how these particles move underground remains a major scientific challenge because existing models do not accurately represent how particles behave in natural soils. This project seeks to improve understanding of how very small…
