  • 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, ...

  • World`s Most Advanced and Easiest to Use Sonic Water Level Meters

    A common theme among drillers and environmental monitoring companies is the need to repeatedly measure water levels and until recently that meant constantly lowering and raising heavy measurement tapes. If you were lucky they wouldn't get stuck or break off leading to spoiled test results and expensive repairs. Eno Scientific has solved this problem by manufacturing the ...

  • Soils Characteristics of The Bassendean and Spearwood Sands of the Gnangara Mound (Western Australia) and their Controls On Recharge, Water Level Patterns and Solutes of The Superficial Aquifer

    The flow pathways of water in the soils of the Gnangara Mound are highly irregular and depend upon the moisture content, the repellency and preferential wettability potential of the soils. The occurrence of preferential flow is more evident in dry soils. As the soil wets during the rainy season, the water repellence and differential wettability decreases, the fingering and the preferential flow ...

  • 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 ...

  • Landfill site improvement condition for PPC permit

    The installation is a landfill site licensed for the disposal of inert waste. It lies in a potentially sensitive location on the flood plain of the River Great Ouse, near Milton Keynes and it is therefore important to the client to ensure good environmental monitoring is undertaken. The site is divided into two sections, (the north western area and the south eastern area) by the River Great Ouse, ...

  • NEW GROUNDERWATER REPORT PREPARED FOR KALGOORLIE CONSOLIDATED GOLD MINES(KCGM) IN WESTERN AUSTRALIA

    For many of our clients the impact of water abstraction and use is an element of their operation which requires long term monitoring and analysis. Results are often compared to baseline data so that impact of operations can be understood and, if necessary, modified. This is frequently an arduous task with some of our clients having more than a 100 boreholes which are regularly monitored. This ...

  • Using distributed temperature sensors to monitor an Antarctic ice shelf and sub-ice-shelf cavity

    ABSTRACT. Monitoring of ice-shelf and sub-ice-shelf ocean temperatures represents an important component in understanding ice-sheet stability. Continuous monitoring is challenging due to difficult surface access, difficulties in penetrating the ice shelf, and the need for long-term operation of non-recoverable sensors. We aim to develop rapid lightweight drilling and near-continuous fiber-optic ...
