The subject of the tender is the agreement of a framework contract for the implementation of services for geophysical development control and condition measurements at groundwater measuring points and wells in areas with groundwater, some of which is very heavily contaminated with organic compounds.

Framework agreement 2024-2027 on geophysical development control and condition measurements at groundwater measuring points and wells.

Measurement and investigation methods to be used are video camera inspection, caliber log, focused electro log, neutron-neutron log, gamma-gamma density log, temperature/electrical conductivity log, pH value log, flowmeter and packer flowmeter. Accompanying activities are overlayers of the GWM / wells with clear water, pumping operation, water level measurements, plumbing and the documentation of the work carried out. Carrying out field work in compliance with occupational health and safety for work in contaminated areas.

Expansion control measurements at approx. 32 groundwater measuring points (total measuring distance approx. 800 m, average measuring section 25 m) and 12 wells (total measuring distance approx. 230 m, average measuring distance 19 m) and condition measurements at 74 wells (measuring section approx. 1,410 m, average measuring section 19 m).
