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 31 May 2031.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 September 2031.

Abstract

Water often contains dissolved ions. They are atoms or molecules that bear electric charge. Seawater contains sodium and chloride ions. Industrial wastewater, groundwater, and water produced by fossil fuel extraction contain many other ions. Technologies to separate ions from these water sources can provide freshwater, remove pollutants, and improve manufacturing processes. Some of the ions include critical minerals…
