Brownfield sites are often perfect for developments, as they tend to be in developed areas with existing infrastructure already set up. – This can open the door to getting disused land back into use again. However, as so many brownfield sites have industrial or commercial histories, groundwater can be a challenge for planners and developers.
One of the primary risks is legacy contamination. In some cases, these can find their way into groundwater after travelling down soil layers and might reach adjacent streams/brooks or basements and even nearby houses as they creep underground.

The groundwater levels can be a problem as well; High water tables can cause groundwater to enter excavations, groundworks delays and additional time spent on dewatering. It can also impact foundation design, drainage systems and whether or not features such as basements (or in some areas soakaways) are feasible.
Local authorities and regulators require the documentation as part of planning to demonstrate what assessment has been undertaken about groundwater risks. It may involve a Phase 1 Desk Study, and as suitable, the next phase is typically a more involved activity like a Phase 2 Site Investigation if the preliminary results from your desk study point to potential issues on site.
Developers will either need routine monitoring, a schedule for further classification or robust protective measures depending on results.
Groundwater conditions also vary on a seasonal basis. A site that simply looked manageable in the summer may be inaccessible following a wet winter.
Fortunately, most groundwater problems can usually be remedied with the proper course of action. Integrating an expert earlier allows you to see what the risks are, avoid surprises and keep your project on time.
