TLDR
I consider riparian buffers to be the most important factor influencing nonpoint-source pollutants entering surface water in many areas of the USA and themost important wetlands for surface water quality protection.Abstract:
Because of wet soils adjacent to the streams, riparian buffers are frequently present between farming and urban activities on the uplands and small streams. These riparian areas have been shown to be very valuable for the removal of nonpoint-source pollution from drainage water. Several researchers have measured >90% reductions in sediment and nitrate concentrations in water flowing through the riparian areas. The riparian buffers are less effective for P removal but may retain 50% of the surface-water P entering them. I consider riparian buffers to be the most important factor influencing nonpoint-source pollutants entering surface water in many areas of the USA and the most important wetlands for surface water quality protection.read more

Challenges to incorporating spatially and temporally explicit phenomena (hotspots and hot moments) in denitrification models
Peter M. Groffman,Klaus Butterbach-Bahl,Robinson W. Fulweiler,Arthur J. Gold,Jennifer L. Morse,Emilie K. Stander,Christina L. Tague,Christina Tonitto,Philippe Vidon +8 more
TL;DR: In this article, the authors describe the prospects for incorporating hotspot and hot moment phenomena into denitrification models in terrestrial soils, the interface between terrestrial and aquatic ecosystems, and in aquatic ecosystems.
Flux and Sources of Nutrients in the Mississippi-Atchafalaya River Basin
Donald A. Goolsby,William A. Battaglin,Gregory B. Lawrence,Richard S. Artz,Brent T. Aulenbach,Richard P. Hooper,Dennis R. Keeney,Gary J. Stensland +7 more
TL;DR: In this article, the authors address the following two questions: 1) What are the loads (flux) of nutrients transported from the Mississippi-Atchafalaya River Basin to the Gulf of Mexico, and where do they come from within the basin? 2) What is the relative importance of specific human activities, such as agriculture, point-source discharges, and atmospheric deposition in contributing to these loads?

Nutrient dynamics at the interface between surface waters and groundwaters
TL;DR: In this paper, the surface water/groundwater (SW/GW) interface is a crucial control point for lateral nutrient fluxes between uplands and aquatic ecosystems and for upstream/downstream (longitudinal) processes in lotic ecosystems.

The use of constructed wetlands for removal of pesticides from agricultural runoff and drainage: a review.
TL;DR: The results of the survey revealed that the highest pesticide removal was achieved for pesticides of the organochlorine, strobilurin/strobin, organosphosphate and pyrethroid groups while the lowest removals were observed for pesticide of the triazinone, aryloxyalkanoic acid and urea groups.

Role of the riparian zone in controlling the distribution and fate of agricultural nitrogen near a small stream in southern Ontario
TL;DR: In this paper, Watershed water flow and geochemical measurements were taken along a transect of monitoring wells extending across the riparian area into an agricultural field, and a sharp decline in both nitrate and chloride concentrations was observed near the field-riparian zone boundary.
