The document summarizes a study that monitored roadway runoff and developed design guidance for roadway BMPs. Field studies were conducted at six sub-basins near an intersection of I-80 and I-680 in Omaha, Nebraska. Water quality samples found metals, COD, TSS, and TDS to be major contaminants in runoff. Roadside vegetation was effective at reducing runoff. The existing detention basin provided some pollutant load reductions. Based on results, design guidance was created for BMPs like vegetated swales, bioretention cells, and sand filters to treat roadway runoff.
This document summarizes a case study of balancing wetland and stream preservation with stormwater management for a development project. The initial development proposal impacted wetlands and streams, but these impacts were avoided and minimized through design revisions. Additional mitigation included onsite wetland creation. However, the proposed regional stormwater management ponds could impact water quality in the streams. Alternative approaches were developed that focused on managing stormwater in upland areas before release into waters and wetlands. A monitoring plan was also implemented to evaluate impacts. Through these measures, growth was accommodated while avoiding impacts to resources and maintaining effective stormwater strategies.
This document summarizes a study on stormwater impacts to McVicar Creek. The study aimed to: identify impacts; characterize them through a stream assessment; identify 3 representative sites; pursue further research; and develop remediation recommendations. The initial assessment identified 3 sites - Court Street, Castlegreen, and County Fair - for further study. Additional data collection and stakeholder workshops were held. The workshops developed stormwater management objectives and site-specific recommendations. For Court Street, increased enforcement and education were recommended. For Castlegreen, investigating infrastructure and partnering with local groups. For County Fair, educating landowners and considering end-of-pipe solutions were recommended. The final recommendations emphasized objectives and further stakeholder

Study: The Potential Environmental Impacts of Fracking in the Delaware River ...Marcellus Drilling News
A $320,444 "study" bought and paid for by Big Green groups (the William Penn Foundation and Delaware Riverkeeper) that reportedly shows the impacts (i.e. harms) that would occur if shale drilling were allowed in Wayne and Pike counties in Pennsylvania. Currently those counties cannot drill for shale energy because they are part of the Delaware River Basin Commission's jurisdiction and the DRBC does not allow drilling. This study, using Big Green money, is meant to keep it that way--no drilling ever in those counties, denying landowners their Constitutional rights. It is a sham study with a pre-determined outcome authored by CNA, a non-profit organization that sells itself to the highest bidder.
California regulates stormwater through permits that establish requirements for construction sites. The state regulates stormwater as a pollutant and point source, requiring permits under the Clean Water Act. Regulations establish risk levels for construction sites based on sediment risk and receiving water risk. High risk sites have more stringent controls. Permits set numeric limits for turbidity and pH and require Storm Water Pollution Prevention Plans. The state also regulates wetland and stream fill through policies of no net habitat loss, requiring replacement of impacted areas.

Review on Hydrodynamic Modelling of Desalination Plants Brine Effluent Marine...IJAEMSJORNAL
This document provides a review of hydrodynamic modeling of brine effluent from desalination plants discharged into the marine environment through outfalls. It discusses several past studies that have modeled brine dispersion using software like CORMIX and numerical models. Key findings from the studies include that dilution of brine to 1 ppt or lower within a reasonable distance is needed to limit environmental impacts. Outfall design aspects like inclination angle, discharge velocity, and use of single versus multi-port diffusers can influence initial dilution and dispersion of the brine plume. Tidal currents may cause brine plumes to oscillate and temporarily return to the outfall location, increasing local salinity. More data and unified approaches are still

The document discusses the importance of monitoring land-ocean carbon fluxes at a pan-European scale. It notes that while there is a significant amount of existing data on carbon fluxes, the data is scattered and not standardized. The document recommends establishing a coordinated monitoring network that builds on existing water quality monitoring networks to regularly measure carbon and other parameters in Europe's major rivers, lakes, and coastal waters. Targeted process studies and numerical modeling could help extrapolate the monitoring data and further scientific understanding of carbon fluxes across the land-ocean continuum.
Submission of Lake Ontario Waterkeeper - Reviewing Canadian Nuclear Safety Co...LOWaterkeeper
The Port Hope Area Initiative (PHAI) is an internationally significant undertaking. It is the biggest radioactive waste clean-up project in Canadian history, and involves one of the largest nuclear waste holding facilities in North America. The PHAI is comprised of two distinct projects: the Port Hope waste relocation project (“Port Hope Project”), and the Port Granby waste relocation project (“Port Granby Project”). Together, both projects seek to clean up a combined two-million cubic metres (m3) of low-level radioactive waste from various sites across Port Hope and Port Granby.
The Port Hope Project involves excavating 1,223,250 m3 of historic radioactive waste from several sites around the town of Port Hope to a Long-term Waste Management Facility (PH LTWMF) just north of the community. The project was subject to an environmental assessment (EA) under the Canadian Environmental Assessment Act, 1992 (CEAA, 1992) which was conducted from 2001 to 2007. In 2009, the CNSC granted a five-year Nuclear Waste Substance Licence to Atomic Energy Canada Limited (AECL) to implement the project. In 2012, AECL applied to have its licence extended for ten years. This was granted by the Canadian Nuclear Safety Commission (CNSC), making the current licence valid until December 31, 2022.
The Port Granby Project involves the removal of 450,000 m3 of historic radioactive waste from the existing and poorly contained Port Granby waste management facility to a new above ground waste management facility (the PG LTWMF) 700 metres north of the Lake Ontario shoreline. The Port Granby Project was also subject to a federal EA under CEAA, 1992 and the project was approved in 2009. After a public hearing in September 2010, the CNSC granted AECL a ten-year licence to implement this project.
In the last five years, some progress has been made to ensure the initiative supports a more swimmable, drinkable, and fishable Lake Ontario. But more work is still needed.

Internationally, poor landfill leachate management has caused groundwater and environmental pollution. In Ireland, 95% of landfill leachate is sent to municipal wastewater treatment plants for treatment, but increasingly stringent regulations have increased treatment costs. As landfills can generate leachate for over 30 years after closure, sustainable long-term leachate management is needed. This project aims to characterize Irish landfill leachates and evaluate the impacts and costs of on-site versus off-site leachate treatment to develop management guidelines. Preliminary results found most leachate parameters exceeded levels that can inhibit wastewater treatment.
Oil and gas are essential parts of a sustainable future. Though these are finite energy resources and sources of greenhouse gas emissions, the world continues to require their production. For this reason, it is imperative that we consider improved industry practices.
To begin, the audience will be presented with the most basic principles of sustainability pertaining to oil and gas operations, including SPE’s position on this matter. When oil is discovered at a location, decisions and guarantees cannot be made without considering the project’s life cycle. Our commitments must be demonstrated consistently along each stage of a project in direct consideration of a sustainable future.
Next, several case studies relating to sustainability, integrating the realities of the social license to operate and operations will be presented to the audience, detailing the required steps for the successful execution of any project facing challenging conditions.
The presentation will conclude by underlining that the inclusion of internal and external stakeholders will only enrich the project and, therefore, pave the road to success. It is our responsibility to create a culture of operational professionalism and reliability through active participation. In order to counterbalance the world’s energy demand, we must produce oil and gas while considering that the more efficiently the energy is produced, the more affordable the energy will be. The oil industry is not only committed to its own sustainability but also to the sustainability of our planet.
This document provides an overview of the Cloud to Coast research project which aims to improve the ability to predict exposure and health impacts of pathogens in coastal waters. The project involves developing an integrated model of hydrology, hydraulics and transport of faecal indicator organisms from source in catchments to coastal areas. Extensive sampling and monitoring is being conducted in the Ribble catchment to inform models, which will then be used to assess health impacts under different scenarios and inform policy.
The research developed a hydro-environmental numerical model called DIVAST to more accurately predict flood peak elevations, inundation extent, hazard risk, and water quality levels. The model has been implemented in commercial codes used by major organizations worldwide on large projects, mitigating risks from floods and water quality issues. It has resulted in marked environmental, health, economic and industrial benefits.

Integration of the MODFLOW Lak7 package in the FREEWAT GIS modelling environmentMassimiliano Cannata
The MODFLOW Lake Package is integrated into the FREEWAT GIS environment in order to simulate surface water - groundwater interaction using state of the art techniques for numerical simulations, thus allowing the improved consideration of surface water bodies for water resources management. Surface water bodies, both stationary and flowing, can strongly affect groundwater elevations and flow patterns which in turn may affect the qualitative and quantitative state of groundwater resources. With the advancement of numerical simulation techniques and increased model complexity, FREEWAT facilitates the usage of the lake package through existing QGIS tools to edit model layer geometry as well as an intuitive and simple user interface for the specification of constant and time variable lake properties as defined through MODFLOW.
This document summarizes the development of a new self-regulating tide gate (SRT) design by the Environment Agency. Key points:
- The SRT allows controlled tidal exchange to restore intertidal habitats while maintaining flood protection. Previous proprietary designs had to be imported.
- The new design is float-operated and adaptable to different locations. Prototypes were installed at Seaton, Devon and Lymington, Hampshire to demonstrate uses.
- The design meets criteria for being locally produced, fail-safe, low maintenance, and facilitating fish passage. Monitoring shows it operates automatically in response to tides as intended.

Geological Society North West Group 2011 2012 Programme Finalchrisberryman
This document provides the programme details for the North West Regional Group for the 2011/2012 year, including dates, times, speakers and topics. It lists 12 events from October 2011 to May 2012 covering various topics within earth sciences such as the role of geologists in radioactive waste disposal, engineering geophysics, conceptual designs for geological disposal facilities, groundwater ecosystems, hot topics in earth sciences, geohazards in the UK, and shale gas. The events are to take place at various venues in the Manchester and Liverpool areas. Contact details are provided for anyone interested in attending.
This document discusses tests used to measure aquifer hydraulic properties for contaminant hydrogeology. It explains that aquifer properties are typically characterized at a large scale using pumping tests, but contaminant transport is influenced by heterogeneity at smaller scales. Accurately characterizing hydraulic conductivity spatial variability at finer scales is important for effective remediation system design, as contaminant plumes and high flux zones can span orders of magnitude over short distances. Failing to detect this heterogeneity could result in over- or under-designed remediation systems.
This document provides an update on research projects studying monitored natural attenuation (MNA) at the Site for Innovative Research on Natural Attenuation (SIReN). Three major projects are described. 1) A project developing a dipole flow reactive tracer test to assess MNA and inform risk assessments. Field and lab tests have provided hydraulic and reactive properties. 2) A project using chemical fingerprinting and molecular analysis to monitor benzene attenuation and associated microbial communities. 3) A demonstration of a portable biosensor system to rapidly assess toxicity and guide sampling. Together the projects aim to advance tools for MNA assessment and demonstration.
This document describes Project SIReN, a national initiative in the UK for researching monitored natural attenuation (MNA) of contaminated land. Project SIReN established a research site to study MNA under UK conditions. Characterization of the site revealed contamination in shallow groundwater including BTEX, trimethyl benzenes, and naphthalenes. Ongoing research projects are helping demonstrate MNA and improving understanding of natural attenuation processes in UK geology. The goals of Project SIReN are to promote MNA, facilitate its acceptance as a risk management option, and develop cost-effective approaches to demonstrating MNA efficacy.
