  • Search and Rescue Demo With Deep Trekker

    Search and Rescue operations are a large part of police divers jobs. While it is never nice to hear about a drown victim, the work that police divers do is extremely important to provide closure to the families involved. Each time a brave diver enters the water there is a number of risks involved, especially when the specific task at hand holds so much weight. One of the most ...

  • Case Study - Groundwater Discharge Permit - Plymouth, Massachusetts

    The process of obtaining a groundwater discharge permit for a subdivision scale septic absorption system was faciliated by using the advanced GIS features within EnviroInsite. Geologic features were downloaded and presented at the site scale along with the subdivision boundary and potential downgradient receptors. A cross-section was created showing the detailed soil descriptions, water levels ...

After attendee self-introductions, Hayes asked if corrections ...

  • Private rights, public interests and water use conflicts: evolving water law and policy in Michigan

    Water conflicts are rare across Michigan's history. As a result, water rights have received little attention by courts or the legislature. Traditionally, the common law of water rights in Michigan embraces the riparian doctrine for surface water and provides landowners with the right to use groundwater. However, two recent changes in common and statutory law significantly modify the legal ...

  • Recovery of Ruthenium and Other PGMs from Spent Petrochemical Catalysts

    The recovery of platinum group metals from spent petrochemical catalysts has economic benefits by the protection of the supply chain of these valuable and rare metals, thereby helping to create a sustainable value chain in the petrochemical industry for catalysts. Introduction The platinum group metals (PGMs) are used extensively in catalysts for the petrochemical industry owing to ...

  • A new frontier in Texas: managing and regulating brackish groundwater

    The challenge of providing access to clean water is visible in Texas, where chronic drought coincides with increasing water demand. The 2012 Texas State Water Plan reports a 2,700 million cubic metres (MCM) gap between freshwater supply and demand in 2010, a number predicted to grow to 3,100 MCM by 2060. Due to the difficulty of reducing water demand, policy makers and water providers are ...

  • Towards an effective protection of groundwater resources: putting policy into practice with the drinking water protection file

    Groundwater in the Netherlands is a major resource for drinking water. As such it must be carefully monitored and managed. Evaluation of the European Water Framework Directive (EU-WFD) showed that protection of this valuable resource needs improvement. The Drinking Water Protection File identifies necessary measures needed per water abstraction site. The Protection File is part of the Dutch ...

  • A grid-based integrated surface–groundwater model (GISMOD)

    A distributed hydrological model, the Grid-based Integrated Surface-groundwater MODel (GISMOD), was developed to simulate hydrological processes by considering water interaction among different soil layers. The model integrates six modules. Basic information on catchment, such as the flow direction and the drainage network, can be obtained automatically from digital elevation model (DEM) data ...

  • Food industry needs to step up on responsible groundwater use

    Californians are all too familiar with what happens when water is not treated as the precious resource it is. But most of us are unaware of the enormous power we have through our day-to-day purchases, social media campaigns and petition drives to push food companies to take more responsibility in protecting global water supplies. Food production, the world’s biggest water user, is a major ...

  • Managed aquifer recharge: the widening gap between law and policy in India

    The past decade has witnessed discussions on various options to overcome groundwater depletion, such as rainwater harvesting (RWH) and ‘artificial recharge’ methods. This paper addresses law and policy issues relating to managed aquifer recharge (MAR). Based on an analysis of the National Water Policy of India and water polices and laws of the Indian states, a concrete case study, namely ...

  • Tools for assessing sea level rise vulnerability

    Increasing sea level has the potential to place important infrastructure we rely on every day at risk, yet we lack good data to make decisions on what to do, when, and with what priority. The objectives of the research were to develop a method for estimating the time scales for various increments of sea level rise (SLR) throughout the 21st century, develop an accurate methodology for predicting ...

  • Solutions-IES Completes First Risk-Based Remediation Under New State Law

    A former electronics manufacturing facility in North Carolina (NC) had conducted groundwater remediation since 1991 to remediate low-level chlorinated solvents.  Under RCRA, the originally approved Remedial Action Plan (RAP) recommended pump and treat (P & T with air stripping and carbon) to capture and remove the contaminants.  Upon coming on board the project, Solutions-IES ...

  • Improved light-transmission method for the study of LNAPL migration and distribution rule

    In this study, diesel was selected as a pollutant to study the migration and distribution rule of light non-aqueous phase liquid (LNAPL) in the simulated vadose zone. Saturation was regarded as a critical parameter to reflect the LNAPL migration and distribution rule. To get LNAPL saturation distribution figures, an image processing method of saturation was established to improve ...

  • Groundwater management in China

    After introducing groundwater development and other issues, the paper analyzes China's groundwater management system and its problems, and provides suggestions for improving the system. Increasing water demand since the 1970s has resulted in severe groundwater overdraft, water level decline and water quality degradation in China, but the current management system is not able to provide an ...

  • Risks from Renegade Nanoparticles during field deployments within NanoRem

    The aim of NanoRem is to support and develop the appropriate use of nanotechnology for contaminated soil and groundwater remediation. NanoRem focuses on facilitating practical, economic and exploitable nanotechnology for in-situ remediation. This can only be achieved in parallel with a comprehensive understanding of the environmental risk-benefit balance for the use of nanoparticles (NPs). One ...

  • What you don`t know can hurt you

    What You Don't Know Can Hurt You: The ins and outs of site inspection in a new era As NPDES permits strive to improve storm water runoff, site inspections and monitoring put an increasing demand on businesses and municipalities to evaluate and report their program performance. One of the primary goals of the permits is to gather additional data through site monitoring. The permits now are ...

  • Interpretation of aged sorption studies for pesticides and their use in EU regulatory leaching assessments

    First‐tier regulatory exposure assessments for pesticides assume that pesticide sorption is instantaneous and fully reversible. In EU regulatory guidance, an increase in sorption over time (‘aged sorption’) can be considered at the higher tier to refine predicted environmental concentrations in groundwater. Research commissioned by the UK Chemicals Regulation Directorate (CRD), funded by ...

  • Groundwater, flooding and hydrological functioning in the Findhorn floodplain, Scotland

    A large floodplain of the River Findhorn, northeast Scotland, was investigated using hydrogeological and hydrochemical methods (including residence time indicators) to characterise groundwater/surface-water coupling and groundwater flooding. The study demonstrated widespread stratification within the floodplain: shallow (<8 mbgl) deposits are highly permeable (100 m/d); deeper deposits ...

  • Water management problems in the Copiapó Basin, Chile: markets, severe scarcity and the regulator

    This research focuses on the determination of the factors that led to the failure of water management in the Copiapó Basin in Chile. Interestingly, the existence of full private ownership and free tradability of water rights has not prevented the overexploitation of groundwater resources. In the paper, firstly, water regulation and the role of the regulator in Chile are briefly discussed. ...
