Implementation and operation of groundwater control and monitoring networks

Research, evaluation and use of groundwater. Technical assistance for the exploitation of aquifers.

More than 35 years of experience in research and exploitation of groundwater. Control and surveillance of groundwater under ISO 17020 accreditation in the field of continental waters and landfills.

We have the most advanced means and extensive experience in the use of geographic information tools, CAD design and editing and digital models, as well as the design and creation of personalized databases and their direct publication via the web.

We operate and maintain the main groundwater control networks in operation in the CAPV

  • Hydrogeological studies

    • Characterization of hydrogeological units, inventories of water points, foronomic, piezometric and water quality control.
    • Development of conceptual models of operation and mathematical modeling of flow and transport.
    • Evaluation, management of resources, reserves in aquifers and bodies of water.

  • Design, execution and equipment of groundwater research and exploitation probes.

    • Project and construction management of piezometer, surveys and wells.
    • Hydrogeological testimony, hydrogeological characterization in small diameter boreholes, from 2”, by pumping or air-lift.

  • Production tests, pumping and reinjection tests.

    • With own equipment from 2” to 10”. Test flow rates between 0.5 and 60 l/s and manometric heights of up to 120 m.c.a.
    • Stimulation and development of wells and probes: air-lift, acidification, pistoning, overpumping,…
    • Disinfection of boreholes.
    • Equipment for exploitation surveys. Complex pumping and reinjection installations with seasonal inversion for open geoexchange circuits.
    • Endoscopic inspections and diagraphs of wells and surveys, with submersible video cameras with capacity for 200 and 300 m depth.
    • Regeneration of extraction and reinjection probes.
    • Diagnosis of pathologies, design and execution of mechanical and chemical treatment for the regeneration of the borehole. Control and verification of treatment efficiency.

  • Design, execution, and exploitation of hydro-meteorological control networks.

    • Execution, equipment and operation of gauging stations. Meteorological, limnimetric and piezometric stations. Equipment of hydrochemical control points through continuous pumping and quality control: CE, Temperature, NH3, VOCs,…
    • Groundwater quality control networks aimed at meeting the objectives of the MAS, Control networks for specific contaminants: Hg, VOCs, NO3, NH3,… in groundwater. Execution and exploitation of networks, some of them, in continuous operation since 1995. Control and remediation of groundwater contamination through ex-situ techniques.
    • Groundwater sampling according to ISO 5667, in boreholes and wells. Preservation and conservation of samples. Physico-chemical and microbiological analysis in an ISO 17025 accredited laboratory and report of results.
    • Assistance to the exploitation of groundwater. Monitoring of the evolution of the exploitation, control and extraction guidelines, modeling, tests with tracers, studies of demands, conditions…
    • Hydrogeological control and diagnosis of MSW (PVA) landfills. TELUR is accredited by ENAC as an ISO 17012 inspection entity in the field of landfills.
    • Design, construction and operation of hydrometeorological control networks: leachate gauging stations, piezometers, pumping tests, groundwater/biogas ratios,…

  • Perimeters of protection

    of groundwater abstraction and exploitation.

  • Processing of concessions

    and discharge concessions. Processes for obtaining mineral water declarations.

  • Control and automation of the management of ecological flows in hydroelectric plants

    in hydroelectric power stations, catchments and other uses. Instrumentation of canals and overflows, management of flow alarms, being able to verify compliance with the conditions of the concession.
