Why Groundwater Remediation Is More Like Tracking a Criminal Than Cleaning a Spill

The picture you probably have in your head when someone mentions the term groundwater remediation – some big machinery cleaning an industrial and contaminated site, is almost right. Except that it misses a big part that comes before any treatment work even begins. Groundwater remediation is more like tracking a criminal than cleaning a spill. Why? Because tracking a criminal is detective work.

Groundwater contamination is not a static, immobile body. Instead, it is a changing, moving body with its own history of movement and source. The contaminant’s state is affected by some factors, including the subsurface geology, rainfall, abstraction, fluctuations in the water table and even the contaminant itself. Understanding a contaminant plume requires reconstructing its history and movement, and the best way to do this is by using the available evidence.

The analogy to a criminal is apt here, because tracking a criminal is a detective’s work. It involves a thorough examination of the crime scene (including cataloguing evidence), hypothesising a sequence of events leading to the crime, a hypothesised source or mechanism of the crime and predicting as much of the crime’s future behaviour as is possible. Similarly, for the specialist in groundwater contamination remediation, reconstructing the contamination plume’s past, present and future (as much as is possible) requires understanding its source and mechanism.

If any of the questions are wrong, the treatment strategy will target symptoms, not the cause. The plume is almost certainly still moving. And the problem is not yet solved. The site is not treated; it is merely observed.

Groundwater remediation is almost completely detective work, not preliminary work to remediation. In fact, remediation is detective work.
