There is often discussion about the source of pollution. The liability of the different parties is then not clear and the distribution of the associated costs is delayed as long as the discussions are going on.
In this type of situation, flux data provides a more objective yardstick for allocating liability. The determination of water fluxes and mass fluxes can usually establish a direct relationship between costs and pollution.
The endless discussions between parties, often each with their own sampling method, can be avoided. The flux measurements provide a more objective framework for demonstrating liabilities. Not only is the contamination mapped out, but also the direction in which it is moving.
Pump regimes, use of activated carbon and other resources can be related to the flux data. In addition, a flux campagin can be a benchmark for measurements at various neighbouring sites. There will be no difference between sampling methods used by different parties.
