The last 60 years has seen unprecedented groundwater extraction and overdraft as well development of new technologies for water treatment that together drive the advance in intentional replenishment known managed aquifer recharge (MAR). This paper is first attempt to quantify volume MAR at global scale, illustrate advancement all major types relate these research regulatory advancements. Faced with changing climate rising intensity extremes, an increasingly important management strategy,...
Abstract This study examines the relationship between wetlands hidden beneath forest canopy (‘cryptic wetlands’) and dissolved organic carbon (DOC) export to streams lakes in forested ecosystems. In Turkey Lakes Watershed (TLW), located Algoma Highlands of central Ontario, Canada, there is substantial natural variation average annual DOC (kgC ha −1 year ), ranging from 11·4 31·5 kgC catchments with no apparent wetlands. We hypothesized that was related cryptic Cryptic were derived manually...
By using high-performance size exclusion chromatography (HPSEC) and reversed-phase liquid with on-line three-dimensional excitation emission matrix fluorescence detection, we measured properties of natural organic matter (NOM) as a function molecular (MS) polarity. The work was carried out Suwannee River Fulvic Acid, Aldrich Humic naturally occurring river NOM sample. Significant differences in maximum pattern were found separated chromatographically based on MS There existed strong...
Anthropogenic acid deposition has been implicated in the acidification of surface waters central Ontario and elsewhere. However, alternative sources acidity have proposed, including (i) release protons their accompanying anions by soils (e.g. organic acids) (ii) exchange internally generated for cations atmospherically deposited neutral salts sea salts). We show that a typical acidified catchment first hypothesis is not important during periods high discharge or on an annual basis. As most...
[1] Using measured rates of bubble release and diffusive gas transport (also termed surface aeration), we address the role these mechanisms in emissions nitrous oxide methane from four streams. While ebullition streams rivers has received little study, found that was an important mode emissions, contributing 20%–67% (among streams). Nitrous via were negligible (<0.1% emissions). Total (ebullition + transport) over ten times greater than N2O terms CO2 equivalents. Rates highly variable,...
Managed aquifer recharge (MAR) is part of the palette solutions to water shortage, security, quality decline, falling tables, and endangered groundwater-dependent ecosystems. It can be most economic, benign, resilient, socially acceptable solution, but frequently has not been implemented due lack awareness, inadequate knowledge aquifers, immature perception risk, incomplete policies for integrated management, including linking MAR with demand management. achieve much towards solving myriad...
We examined the extent to which photolytic and nonphotolytic decomposition rates of dissolved organic carbon (DOC) could account for annual retention or loss DOC inputs in lakes (retention is equal stream plus atmospheric minus discharge equivalent storage sediments degassed atmosphere). Losses atmosphere were large, averaging 38 70% total seven study between 1980 1992. Up 50% was lost as inorganic C when exposed solar radiation during 6 11 day surface exposures bottles whereas lake...
This study presents a simple model of dissolved organic carbon (DOC) loading to surface waters that is applicable headwater catchments in forested regions on glaciated landscapes. Average annual DOC export was highly variable among the 33 experimental along an east‐west transect, ranging from 0.90 13.74 g C/m 2 /a. It hypothesized proportion wetlands within would explain majority variation average export. To test this hypothesis, digital terrain analysis used derive automatically under both...
Use of Managed Aquifer Recharge (MAR) has rapidly increased in Australia, USA, and Europe recent years as an efficient means recycling stormwater or treated sewage effluent for non-potable indirect potable reuse urban rural areas. Yet aquifers have been relied on knowingly water storage unwittingly treatment millennia. Hence if 'leading edge' is defined 'the foremost part a trend; vanguard', it would be misleading to claim managed aquifer recharge leading edge technology. However taken...
Sustainable use of groundwater is becoming critical in India and requires effective participation from local communities along with technical, social, economic, policy political inputs. Access to for farming also an emotional complex issue as their livelihood survival depends on it. In this article, we report transdisciplinary approaches understanding the issues, challenges options improving sustainability States Gujarat Rajasthan, India. project, called Managed Aquifer Recharge through...
Photochemical transformation of dissolved organic matter (DOM) has been studied for more than two decades. Usually, laboratory or "in-situ" experiments are used to determine photodegradation variables. A common problem with these is that the done at higher ambient temperature. Five were effect temperature on photochemical degradation DOM. Experimental results showed strong dependence Mathematical modeling processes revealed different pathways engaged in DOM inorganic carbon (DIC) strongly...
The capture, treatment, and recharge of urban runoff can augment water supplies for water-scarce cities. This article describes trends in stormwater capture potable supply using examples from the U.S. Australia. In water-limited climates, potential exists large scale harvesting recharge, such as neighborhood-scale larger projects. beneficial use to meet nonpotable demands has been successfully demonstrated internationally. However, terms U.S., lack a regulatory framework uncertainty...
Innovation born of necessity to secure water for the U.S. state Arizona has yielded a model banking that serves as an international prototype effective use aquifers drought and emergency supplies. If understood adapted local hydrogeological supply demand conditions, this could provide highly solution security elsewhere. is semi-arid in southwestern United States growing demands, significant groundwater overdraft, surface supplies with diminishing reliability. In response, developed...
