  • GPS-enabled gas analyser finds & proves borehole locations case study

    Prove it? They can now! Landfill technicians and environmental consultants can now find and prove borehole locations with a GPS-enhanced portable gas analyser from Geotech. Its on-board GPS guidance system takes staff to the precise location of the 1000 it can store. It adds the GPS-received location, date and time to the gas analysis record. GPS locations can be added at boreholes or pre-loaded ...

  • Coliform status of water bodies from two districts in Ghana, west Africa: implications for rural water resources management

    Investigations were conducted on the total and faecal coliform status of streams, hand-dug wells and boreholes highly patronised by communities in the West Akim and Kwaebibirem Districts, Eastern Ghana. Total coliform values obtained range from 60–2,672 cfu, 0–680 cfu and 0–128 cfu for streams, hand-dug wells and boreholes, respectively. Faecal coliform values similarly range from 31–1,988 cfu, ...

  • Measuring and interpreting gas flow from landfill boreholes case study

    Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the ...

  • Integration of Subsurface Data Management and GIS to Facilitate Model Calibration

    Abstract The development of numerical codes, as well as pre- and post-processors to support these codes, has made the discipline of groundwater modelling increasingly more automated and efficient. The value of such modelling is reliant on the site-specific data used to build and calibrate the models. The integration of EarthSoft's EQuISÒ Geology and any of several popular modelling environments ...

  • South East framing review

    Drilling a borehole on a farm can cost less than a conventional water supply and cut the carbon footprint from pumping and treating mains water. "There is an environmental as well as a cost argument for drilling a borehole,' said Ben Nicholls, joint managing director with his brother Richard of Nicholls Boreholes, which is based in West Sussex. Nicholls Boreholes is in an office on an ...

  • 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.
