Investigating The Potential For Nitrate-N Removal In Rhode Island Transient Headwater Streams, Molly Welsh, Kelly Addy, Art Gold, Suzanne Cox

Discovery@URI

Excess nitrogen (N) can have detrimental effects on the environment, particularly in coastal waters where inputs from septic systems and agricultural runoff can lead to algal blooms and hypoxic zones. However, transient headwater streams, which comprise a significant portion of streams in watersheds, may have the potential to remove N given their low flow rates, high surface to volume ratios, long retention times, and hydric soils. We investigated the physical characteristics and N removal capacity of transient headwater streams. Four bromide (Br) and nitrate-N slug tests were conducted in four streams in southern RI. Streams were sampled repeatedly as the …
