  • Waterquality in irrigation canals and boreholes - Greece

    Background Kavala is located in the North East of Greece, 680 km from the capital Athens. The population of the prefecture of Kavala is around 85,000 people. The River Nestos which flows through this prefecture is very important for the agriculture of the area. To allow for a fair distribution of the water for irrigation purposes, a number of Boreholes and canals have been established. The ...

  • Isolate & sample up to 7 zones in one borehole

    CMT Multilevel Systems isolate and monitor up to seven discrete zones in one borehole; monitor 7 zones in the 1.7" (43 mm) System; 3 in the narrow 1.1" (28 mm) System. Both options are low cost. The single tube design makes them fast and easy to drill and install in one day. System flexibility allows port locations and monitoring strategy to be finalized right on site. CMT wells are ideal for ...

  • Scanning proposed borehole locations for Utilities case study

    Environmental and engineering firms often are tasked with performing soil borings for monitor well installation as part of a Phase II Environmental Site Assessment. This task becomes more challenging when the borings are to be installed in gasoline stations, right of ways or other areas where there are numerous underground utilities that are either unmarked or not properly located. GeoView can ...

  • 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 ...

  • 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 ...

  • Leachate Monitoring Alarm System

    A Major Waste-Disposal Operator, Sept 2008 - ongoing Leachate Monitoring at Landfill Site near Reading Design and installation of a GSM-based telemetry system for monitoring leachate level and pumping rates at 5 no. boreholes. An ATEX certified intrinsically-safe depth pressure transmitter was selected due to the presence of explosive gases at the site. A ...

  • Deployment of a Deep Borehole Observatory at the High La ke Project Site, Nunavut, Canada

    Abstract We deployed a deep permafrost observatory in a borehole at the High Lake Project Site (67°22'N, 1I0°50>W), Nunavut, Canada with the aims of (1) investigating the physical and chemical limitations on microbial life within such environments, (2) developing life-detecting technologies for the exploration of life on Mars and (3) constraining the hydrological and thermal ...

  • Abandoning Monitoring Wells: Safety Issues

    Monitoring wells are typically constructed to gauge the extent of contamination, assess water quality and conduct other hydrogeologic studies. Depending on its objective, the monitoring well may remain in use or may be abandoned permanently. When declared inactive, the well is many a times left as it is. Open unused wells are hazardous to life and environment: • Contamination may spread from one ...

  • Water monitoring commences in mines of West Africa

    As Sierra Leone looks to attract a new wave of mining investment in order to boost its economic profile, bringing water mine management standards in line with global best practices has become a priority. Government officials, academia, general citizens and companies have all become committed to improving standards with regards to water management in mining. As a key player in regulation ...

  • A New Multilevel Ground Water Monitoring System Using Multichannel Tubing

    A new multilevel ground water monitoring system has been developed that uses custom-extruded flexible 1.6-inch (4.1 cm) outside-diameter (O.D.) multichannel HDPE tubing (referred to as Continuous Multichannel Tubing™ or CMT) to monitor as many as seven discrete zones within a single borehole in either unconsolidated sediments or bedrock. Prior to inserting the tubing in the borehole, ports are ...

  • Case study - Remote water quality monitoring in South Africa

    Situated in the Mpumalanga province of South Africa, the Xstrata Coal South Africa (XCSA) runs several open cut and underground mining operations producing thermal coal. To ensure their mining operations do not affect the surrounding natural water bodies, the company employs Hydrolab and OTT water quality monitoring equipment with remote data transmission options: the OTT ecoLog 800 water level ...

  • 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 ...

  • Remote monitoring of groundwater pollution using geo-electric techniques in undulating sandy terrain, Western Australia

    Early-time transient electromagnetic sounding (TEM) and DC resistivity sounding techniques have been used to monitor remotely the changes with time of a groundwater pollution plume at a test site on a sand aquifer. A range of techniques for interpretation of TEM sounding data have been evaluated. All of these were successful in identifying expansion of the plume. The most plausible interpretation ...

  • Ethanol production plant monitors impacts to Water supply and Stays in Compliance - Case study

    Application Under current ethanol plant configurations, water use for ethanol production ranges from 4.0 to 6.8 gallons of water required per gallon of ethanol produced. With the average new plant producing 120 million gallons of ethanol per year, water yields in excess of 1,000 gallons per minute are required; therefore adequate water supply is essential to the operation of an ethanol ...

  • 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, ...
