  • Leachate and Groundwater Quality in Lagos, Nigeria.

    ABSTRACT Water as a gift of nature is generally believed to have no enemy. Despite the abundance of fresh water on the earth, many regions are in deep crisis of water shortage due to there being polluted by human activities, or the ever increasing demand by industrialization and high population growth. Thus, groundwater is the alternative source of fresh water in areas where surface water is ...


  • Baseline groundwater quality in unconventional oil and gas fields

    In recent years, expansion of unconventional oil and gas production has prompted significant interest in potential impacts on drinking water resources. In many cases, water quality investigations rely on access to landowner water wells to develop baseline data prior to drilling; respond to spills, complaints, or incidents; or evaluate potential impacts due to drilling, completion, hydraulic ...

  • Wastewater and groundwater

    Nearly 25 percent of the population in the United States—in more than 25 million homes—disposes of wastewater through onsite, or unsewered, systems that return treated effluent to the ground. This is an important public health issue because many of those same homes use wells that rely on groundwater for the drinking water supply. With ...

  • Groundwater Remediation

    Groundwater remediation or clean-up is required when concentrations of contaminants exceed or are expected to exceed predetermined levels for the type of resource that is impacted (Grossman et.al., 2008). For example, lead levels in drinking water should not exceed the EPA action level of 0.015 mg/L. What caused the high levels of lead? How can the lead be removed from the aquifer? (Grossman ...

  • Hydrogeomorphological Controls on Groundwater Quality in the Rattaphum Catchment (Songkhla Lake Basin), Thailand

    The Rattaphum Catchment comprises four major hydrogeomorphic units: mountains, footslopes, plains and inland swamps around a lake system. The area accommodates three main agroecosystems: vegetable, rubber and fruits. During the high-rainfall period, groundwater levels rise near to the soil surface in all agro-ecosystems. The high water levels remain for 3–4 months in the coastal plain, while in ...

  • Seasonal variation of groundwater quality in a part of Guntur District, Andhra Pradesh, India

    Abstract  The area in Guntur district, Andhra Pradesh, India, is selected to discuss the impact of seasonal variation of groundwater quality on irrigation and human health, where the agriculture is the main livelihood of rural people and the groundwater is the main source for irrigation and drinking. Granite gneisses associated with schists and charnockites of the Precambrian Eastern Ghats ...


  • Landfill groundwater monitoring network design and construction quality assurance (CQA)

    The site is an active landfill site situated in the north east of England.  The company managing the site was unhappy with the groundwater monitoring infrastructure around the site margins. ESI Ltd was commissioned to advise on locating and designing ten groundwater monitoring wells.  Following agreement with the Environment Agency, we also provided independent construction quality ...

  • Modelling spatio-temporal heterogeneities in groundwater quality in Ghana: a multivariate chemometric approach

    Chemometric techniques were applied to evaluate the spatial and temporal heterogeneities in groundwater quality data for approximately 740 goldmining and agriculture-intensive locations in Ghana. The strongest linear and monotonic relationships occurred between Mn and Fe. Sixty-nine per cent of total variance in the dataset was explained by four variance factors: physicochemical properties, ...

  • Effect of soil-use on deep groundwater quality in Southern Chile

    This study evaluated the effects of farming activities on the quality of deep well water in Southern Chile. In this area, the use of fertilisers is becoming more widespread and the accumulation and poor management of cattle slurry and silage sub-products increases the risk of contamination. The study was carried out in the province of Osorno, where rainfall occurs all year round (maximum in ...
