We assess contaminated sites on a fine scale according to the type and extent of damage. For the exploration of the site, we use the intrasense® system that we have developed. This enables high-resolution and detailed explorations with exact data relating to small-scale hydrodynamics, geology, and biogeochemical conditions.
The intrasense® system consists of an integrated and coordinated package of measuring processes for the collection of all the relevant groundwater data. The results provide all the information required for the physico-chemical and hydro-geological characterisation of the groundwater and local hydrodynamics, which then allow us to plan and configure the optimum individual NMP application.
During the exploration of our measuring points, we were surprised to discover with intrasense® the presence of several deviating groundwater flow directions at our site. We hadn’t expected such anisotropies but, on the basis of the intrasense® findings, we were able to align our remediation measures in a considerably more effective way.

The essential elements of intrasense® include the determination of the horizontal and vertical groundwater flow direction and velocity, the groundwater pressure level, as well as camera inspections for controlling the measuring points and the detailed determination of the physical chemistry.
The data are collected on a permanent basis or on key dates, checked for their quality, and subsequently used to create the conceptual site model.
In cooperation with Dr. Marc Schöttler, Intrapore offers vertical and horziontal groundwater flow measurements using the Phrealog® system:
Conventional hydro-geological exploration methods do not always provide results with the necessary quality and clarity. This can be the case with insufficient water gauges, water levels which cannot be correlated to other site factors, very flat groundwater gradients or long-distance water networks, for example.
For hydrogeological explorations, the ability to derive the groundwater flow direction and velocity in the aquifer from the groundwater passage at drilled wells is of fundamental importance. This data can be used for the plausibility testing of flow models independently of water level measurements, for example.
Our measurements take place according to an internal quality standard that is characterised by a camera inspection of the well prior to the measurements. In this respect, pipe transitions are located and the condition of the filter pipe is documented. These are important prerequisites to ensure that the measurements can be carried out in appropriate filter tube sections.
Our customers from the areas of water management, civil engineering, geothermal energy and environmental protection appreciate our professional investigative concepts, the technical discussions with our geologists on-site and our detailed reporting which documents the measured results on a clear and transparent basis, as well as our expertise, which is based on our long-standing experience as a specialist service provider.
