Book Synopsis Assessing the Groundwater Contamination Risk of Drywell-induced Stormwater Infiltration Using Analytical and Numerical Methods by : Emily Clare Edwards
Download or read book Assessing the Groundwater Contamination Risk of Drywell-induced Stormwater Infiltration Using Analytical and Numerical Methods written by Emily Clare Edwards and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Drywells are gravity-fed, excavated pits with perforated casings used to facilitate stormwater infiltration and groundwater recharge in areas where drainage and diversion of storm flows is problematic. Historically, drywells have been used as a form of stormwater management in locations that receive high volumes of precipitation; however the use of drywells is increasingly being evaluated as a method to supplement groundwater recharge, especially in areas like the state of California, which currently faces a loss of water security due to the predicted effects of climate change on water occurrence, and the effects of the recent severe drought. Strict regulations currently limit the use of drywells in the northern half of the state; however, drywell field studies have been performed in neighboring states that have led to drywell regulation reform, and more widespread drywell use. A review of the available drywell literature shows that drywells can be an effective means to increase recharge to aquifers; however, the potential for groundwater contamination caused by polluted stormwater runoff bypassing attenuation processes in surface soil and near surface sediment has prevented more widespread use of drywells as a recharge mechanism. Numerous studies have shown that groundwater and drinking water contamination from drywells can be avoided if drywells are used in appropriate locations and properly maintained. The effectiveness of drywells for aquifer recharge depends on the hydrogeologic setting and land use surrounding a site, as well as influent stormwater quantity and quality. These parameters may be informed for a specific drywell site through geologic and hydrologic characterization and adequate monitoring of stormwater and groundwater quality. Detailed characterization and monitoring were performed as part of a drywell field and numerical modeling study conducted in Elk Grove, California, to determine the effects of drywell-induced stormwater infiltration on the local hydrogeologic system. Two drywells were constructed for the project: one in a preexisting stormwater quality basin fed by residential lots, and one at an industrial site. Site stormwater and groundwater were sampled between November, 2014, and May, 2016, and analyzed for contaminants. Results of water quality sampling were used to determine the stormwater contaminants of interest and the concentrations of these contaminants in the stormwater entering the drywell systems at each site. The vertical, one-dimensional transport of these contaminants through the vadose zone from the bottom of the drywells to the seasonal high water table were simulated using a 1D variably saturated flow and transport model and site specific parameters. This was done in order to predict long-term effects of stormwater infiltration on the surrounding hydrogeologic system, as the results of the field study were only indicative of short-term effects. The results of the field study and numerical modeling assessment indicate that the drywells do not pose a risk to local groundwater quality and may be an effective source of aquifer recharge and tool for urban stormwater management.

Book excerpt: "Stormwater infiltration is the most complete approach to stormwater management. Only infiltration can simultaneously solve problems of water quality, flood control, streambank erosion, aquifer recharge, and maintenance of downstream base flows and wetland hydroperiods. Stormwater Infiltration is the first book to explain the principles of natural science on which infiltration is based, how to apply infiltration to any region of the country, and what kinds of results can be expected. It brings into one publication the complete range of necessary information on soils, vegetation, infiltration, hydrology, design criteria, site layout, construction process for surface and subsurface basins, porous paving materials, feasibility, maintenance, and performance. It draws more than half a century's actual experiences from all over the United States to place stormwater management in a context of environmental balance and quality for human life."--Provided by publisher.

Book Synopsis Stormwater Infiltration and Groundwater Integrity by : Kristopher Craig Gallagher
Download or read book Stormwater Infiltration and Groundwater Integrity written by Kristopher Craig Gallagher and published by . This book was released on 2017 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonpoint source pollution captured by urban stormwater runoff is the greatest challenge for surface water quality improvements. Computer-based design tools have been developed to help mediate this issue by guiding end users through the implementation of decentralized stormwater management. The majority of these tools focus on treatment via biofiltration, yet concern regarding this treatment regime is rising. Case studies from research past clearly indicate the susceptibility of groundwater to contamination from extensive anthropogenic activity at the surface. Contaminants, such as nitrates and pathogens, are not completely removed before runoff enters the underground watercourse. Additionally, national and state legislation, which explicitly lists where neglect for groundwater quality is permissible exacerbate concerns. This research analyzes the efficiency the BMP Siting Tool developed by the US Environmental Protection Agency and the Grey-to-Green Decision Support Tool developed by the University of South Florida. The tools were used to obtain cartographic data illustrating suitable sites for bioswales and infiltration basins throughout northern portion of Hillsborough County, Florida. This data was then integrated with the Karst Aquifer Vulnerability Index (KAVI) groundwater vulnerability model. The area of bioswales and infiltration basins that intersected areas of the KAVI model listed as highly vulnerable or moderate-to-highly vulnerable was calculated. This permitted an assessment of which BMP facility had the greatest sitings atop vulnerable areas, respective of the tool. The BMP Siting Tool sited 2.80% of all bioswales and 27.89% of all infiltration basins above vulnerable areas. Likewise, the Grey-to-Green Decision Support Tool sited 21.66% of all bioswales and 9.62% of all infiltration basins above vulnerable areas. These results prompted the development of a supplemental groundwater vulnerability framework to be incorporated into both tools analytical process.

Book Synopsis Urban Stormwater Management in the United States by : National Research Council
Download or read book Urban Stormwater Management in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
Book Synopsis Investigating the Effects of Variable Water Chemistry on Bacterial Transport During Stormwater Infiltration by : Haibo Zhang
Download or read book Investigating the Effects of Variable Water Chemistry on Bacterial Transport During Stormwater Infiltration written by Haibo Zhang and published by . This book was released on 2013 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pathogenic microorganisms and heavy metals have frequently been detected in urban stormwater runoff. Pathogens transport to the groundwater table with the infiltrating water and cause groundwater contamination. A variety of physical, chemical and biological factors have been studied for their effects on bacterial transport. However, the effect of heavy metals has largely been ignored, despite the elevated concentrations common in stormwater runoff. This work examines changes in bacterial and soil surfaces using scanning electron microscopy and energy dispersive X-ray spectroscopy after exposure to synthetic stormwater amended with heavy metals. Sets of batch bacterial sorption experiments were conducted under different conditions by varying heavy metal concentrations in synthetic stormwater and soil exposure history. The results indicate that the presence of heavy metals increases bacterial attachment to soil surfaces. Modeling bacterial transport during stormwater infiltration is challenging due to the variability and complexity of the physical, chemical and biological interactions in the soil-water-bacteria system. This work quantified changes in bacterial attachment under variable solution chemistry using a newly combined rate equation, which varies temporally and spatially with changes in solution chemistry. The relative importance of physiochemical variation on the estimation of bacterial attachment was quantitatively described using two-phase Monte Carlo analysis. A semi-reactive microbial transport model was further developed in HP1 (HYDRUS1D-PHREEQC) with the incorporation of the newly combined rate equation. The model matched observed bacterial breakthrough curves in laboratory column experiments well. This method represents one step towards a more realistic model of bacterial transport in complex microbial-water-soil systems. The developed model was further applied to the investigation of bacterial removal in field bioretention systems. The influent and effluent water samples from bioretention systems in New York City were sampled and analyzed over the summer of 2012 for fecal indicator Escherichia coli. Reduction of the effluent bacterial concentrations was observed and the removal efficiency was up to 66%. The antecedent dry period was found to affect bacterial removal. Shorter antecedent dry period results in higher soil moisture which is favorable for bacteria in soil to persist. The semi-reactive microbial transport model was applied and the modeled bacterial removal efficiency agrees well with observed values with a slight overestimation. This is primarily due to the presence of preferential flow paths in the field bioretention systems, which are not considered in the model.
