  • Soil and groundwater assessment, Northern England

    Project Remediation Strategies were appointed to assist in the identification of a hydrocarbon contamination source that had resulted in significant vapours within a residential property. Further works to asses the nature and extent of soil contamination were also commissioned, together with detailed vapour risk assessments and subsequent vapour remediation works. ...

  • A critical assessment of groundwater governance in Tunisia

    More than 40% of irrigation water currently used in Tunisia is provided by groundwater aquifers, most of which are in a critical state of depletion due to its overexploitation during the last three decades. This paper provides a critical assessment of groundwater management in Tunisia based on interviews with key officials from central and regional administrations, in addition to ...

  • Assessment of groundwater quality in sunamganj of Bangladesh

    Huge quantities of groundwater, particularly from the shallow aquifers, are used for irrigation in Bangladesh and in the absence of adequate surface water in the dry season, irrigation becomes heavily dependent on groundwater. The water quality management is essential for long-term irrigation system as it persuades the soil properties. In irrigation water evaluation, emphasis is given on chemical ...

  • Soil and groundwater assessment, south-east England

    Project Remediation Strategies were appointed to undertake a soil and groundwater assessment to assist a client in understanding the potential environmental liabilities associated with the shallow soils beneath part of the site.  The client was undertaking a phased renewal of the site tank farm areas, which required the excavation and replacement of shallow soils to allow for new ...

  • Development of a groundwater fungal strain as a tool for toxicity assessment

    Despite the significant ecological role in groundwater the value of fungi as indicators of groundwater pollution is not known, as fungi are notoriously challenging to assess for toxicity because of their varied morphological components, in particular their filamentous structures. Hence they remain rarely used in environmental risk assessments and monitoring programs for aquatic systems. We ...

  • Tunnelling in Chalk: Groundwater monitoring and risk assessment

    Morgan Est is constructing a tunnel to carry high voltage electricity cables between two electrical substations.  The tunnel will mostly be excavated in Chalk, with some excavation occurring in the Thanet Sands. ESI was appointed as Morgan Est’s environmental consultant for the project and has managed liaison between Morgan Est, regulators and other stakeholders over the last four ...

  • Sub-watertable landfill groundwater risk assessment

    Client: Waste Management Industry Location: Sub-water table landfill site, UK Services: Data collation and analysis, hydrogeological risk assessment , regulatory liaison and negotiation, Environmental Permit Application support Issues: Sub-water table landfill site, sensitive receptors (major aquifer), potential risk to ...

  • Assessments of Effect of Land-use change in Groundwater Storage

    Assessment of effects due to land use change in groundwater storage is performed in Kathmandu Valley basin of 651 km2. Effect of land use change is found to be more in groundwater than surface water. Increased impervious area due to land use change has been major factor in contributing to decreased infiltration. The ground water storage is depleting due to fact that the extraction of groundwater ...


  • Above Watertable Landfill (Groundwater Risk Assessment)

    Client: Waste Management Industry Location: Co-disposal landfill site Services: Hydrogeological risk assessment, landfill monitoring borehole installation, sample collection and data interpretation. Issues: Change in waste stream and potential risk to groundwater,  Summary: ESI provided site ...

  • Spatial assessment of groundwater demand in Northwest Bangladesh

    Spatial assessment of groundwater demand has been carried out as a part of sustainable water resources management in Northwest Bangladesh. ASTER images are synthesised for extracting the extent of irrigated land. The Penman?Monteith method is used for the calculation of reference evapotranspiration from climate data. Soil information is used for the estimation of water requirement for land ...

  • Soil and groundwater assessment, North-West England

    Project Remediation Strategies were retained to undertake contamination delineation and assessment work at a logistics depot following an accidental release of a large volume of diesel.  An overnight failure in a joint on a pressurised fuel pipeline had resulted in a loss of 15,000 litres of red diesel. Initial response works identified a small proportion of the diesel had ...

  • Integrated fuzzy-stochastic risk assessment for contaminated groundwater systems

    This study advances an integrated fuzzy-stochastic risk assessment (IFSRA) approach for the management of contaminated groundwater systems by systematically quantifying multiple uncertainties associated with site conditions and health impact criteria. The approach is based on fuzzy multi-attribute decision analysis, factorial designs, numerical modelling, and Monte Carlo simulation. The developed ...

  • Assessing climate change impact on root-zone water balance and groundwater levels

    The present study employs regional climate model projections for assessing the impact of root-zone water balance and groundwater levels using crop and groundwater models. The projections from Hadley Regional Model 3 (HRM3) for A1B scenario showed an increase in temperature and rainfall (RF) of 1.8 °C and 328 mm, respectively, during mid-century (MC) (2021–2050) for Indian central Punjab. The ...

  • Evaluation of uncertainty parameters in risk assessment of agricultural chemicals on groundwater contamination

    Risk assessment is meaningful to quantitatively define adverse effects on human health and natural environment and it is possible to choose the most effective action related to groundwater contamination. In this paper, parameter uncertainties in risk assessment in geo-environmental system are examined through a probabilistic application of deterministic contaminant transport model using Latin ...

  • Assessment of groundwater resources using climatic and hydrologic budget methods

    The Pageru River basin is situated in drought prone areas of the Rayalaseema region, Andhra Pradesh, South–India. In the absence of perennial surface water bodies, groundwater is an important source of water and has played an important role in developing industry, agricultural and domestic supply. In the present study, the efforts have been made to assess the groundwater resources using both ...

  • Evaluating groundwater/surfacewater transition zones in ecological risk assessments

    Currently, there is a common perception that the discharge of contaminated groundwater to a surfacewater body does not pose an ecological risk if contaminant concentrations in surface-water samples are below analytical detection limits or at very low concentrations. The transition zone represents a unique and important ecosystem that exists between surface-water and the underlying ground-water, ...

  • Technical Evaluation of Natural Resource Damage Assessments (NRDA) of Groundwater Resources

    Abstract To support a Natural Resource Damage Assessment (NRDA) for groundwater resources impacted by oil or hazardous substances, careful technical evaluation is required to define the nature and volume of the affected groundwater zone and the associated impact on the potential services provided by the affected aquifer and other interconnected water resources. Relative to the baseline ...


  • Assessment of manganese removal from over 100 groundwater treatment plants

    The aim of this study was to make an inventory of water quality and operational parameters which could affect manganese removal through aeration and rapid sand filtration and to establish correlations between these parameters and manganese removal efficiency. The focus of the overview was on manganese removal efficiency in the first aeration-filtration stage of conventional groundwater treatment ...

  • Non-carcinogenic risk assessment of groundwater in South Gobi, Mongolia

    Thirty-nine groundwater samples were collected from wells near the Tavan Tolgoi and Oyu Tolgoi mines in Mongolia and at a relatively pristine site in northern Mongolia during August to September 2013, and analyzed for the concentrations of F−, NO3−, Hg, As, Al, V, Mn, Co, Ni, Cu, Zn, Se, Mo, Cd, Sb, and Pb. A probabilistic risk assessment found that >95% of the population ...
