Laboratory services

Our company owns a well equipped laboratory.

  • Based on a colorometric analysis of chemical solution, we are able to provide analysis of:
      • ammonium ions,
      • nitrates,
      • nitrites,
      • organic substances,
      • selected chemical warfare agents,
      • fluorescence analysis.
  • This method is suitable for analyses of liquid samples, e.g. drinking water, surface waters and groundwater, leachates from solid materials or food, to capture color changes or to detect material color.

Hydrodynamic parameters measurement







  • Our laboratory is equipped with a specialized apparatus constructed for measurement and evaluation of hydrodynamic and migration parameters. The tests can be performed under simulated close to field conditions, if required. We offer:
  • soil permeability measurement,
  • rock samples permeability measurement.

Specialized strength characteristics measurement







  • For determining strength characteristics of rocks or buldings materials we use a specially developed apparatus.
  • Samples are subjected to the linear or pulse pressure with maximum values up to 300 bar. The pulse frequency can vary up to 15 Hz. During loading the sample is closed in a special cell, which allows to apply independent confining pressure. This allows to verify the rock strength characteristics with different lithostatic pressure. These tests can be carried out successfuly also in in-situ.


Field services

Hydrodynamic tests

  • Our hydrodynamic tests provides hydrodynamic parameters that enables determination of water resources yields as well as overal hydrogeological characterisation of the area of interest.
  • Our technical equipment is suitable for hydrodynamic testing in wide range of yields.

Migration tests

  • Migration tests provide data characterizing resistance of a hydrogeological structure against contaminant leaching.
  • For these purposes the company developed tracer test technology utilizing health and environmental safe tracers.
  • The new technology allows continuous monitoring of tracer inflow into a borehole. The new tracing technology fully substitutes environmentaly unfriendly radioactive isotope tracers.

Communication tests

  • Communication tests uncover hydraulic connection between two hydrogeological objects, e.g. a connection between water source and a potencial source of contamination.
  • The technology is completely environmentaly safe and does not increase water salinity or radiation.
  • The technology is able to indicate the tracer inflow even in trace amounts.

Infiltration tests

  • Infiltration tests are required for construction proceeding.
  • Our experts have extensive experience in realization and evaluation of the infiltration tests.

Borehole inspection using TV camera






  • Borehole TV camera system provides unique opportunity to inspect boreholes with diameter of 3.2cm or wider. The camera can reach depths down to 660m. Combination of frontal and side camera views enables a comprehensive and detailed view of objects of interest in a borehole. We offer:
  • verification of borehole technical conditions,
  • perforation condition control,
  • description of the actual borehole construction,
  • inspection of breach in a borehole construction ,
  • reconnaissance for borehole blockage causes,
  • visual inspection of borehole cleaning effectiveness,
  • supplemental geological exploration in non cased parts of a borehole.

Strength characteristics

  • We use a specialy developed equipment to determinate strength characteristics of rocks or conctruction materials.
  • The equipmet enables to load rock or construction parts with linear or pulse pressure up to 300bar.
  • Pulse frequency of the loading can be set up to 15Hz.
  • The test can be applied also in laboratory conditions on specially prepared rock or concstruction material samples.

The limitation is defined by common interpretive fidelity of spatial projections and also depends on individual area of interest. Individual Hydro GeoAnalystIt projects can incorporate data from 4 to 4000 boreholes.
