The importance of water bed and water system analysis for informed and supported solutions

Drought exacerbates water bed contamination

Water beds become more contaminated during periods of drought. This is a particular problem in Belgium, which is ranked in the highest category for water stress [source]. Soil compaction and erosion affect the stability of the water bed and less dilution increases the concentration of chemicals, such as nitrates and phosphates.

It goes without saying that a contaminated water bed also has a negative impact on the water quality itself. The authorities in Flanders and Wallonia want to continue and reinforce the positive trend of improvement by implementing the Water Framework Directive and the Walloon Water Management Plan.

A proven strategy across the hydrological spectrum

Our experts take a holistic approach when examining the composition and quality of the water bed. We map out the entire water system to understand the dynamics between groundwater, surface water, sediment, rainwater, soil, and so on, and to detect (operational) discharges. Our proven strategy includes:

• Data collection: through sediment sampling, drilling, infiltration tests, groundwater monitoring networks with automatic loggers, sampling and monitoring of surface water and groundwater, and silt sampling.
• Analysis: risk assessments for biodiversity and people, based on hydro(geo)logical modelling of groundwater and surface water, quantitative and qualitative soil and laboratory analyses, and ecological knowledge.
• Solutions: using an integrated system analysis, we help you decide on the most sustainable solution for people and the environment, from remediation in the context of earth moving and soil decontamination to drainage strategies and water plans for re-infiltration, irrigation, and wadis at industrial sites.

Informed solutions that generate a basis of support and ensure feasibility

We have broad field knowledge thanks to our many years of experience with multidisciplinary projects and contacts with various advisory bodies, such as the Flanders Environment Agency, the Agency for Nature and Forests, wastewater treatment firm Aquafin, waterway management company De Vlaamse Waterweg, public waste agency OVAM, and others. Our experts combined this knowledge with policy insight to provide you with the best possible information so that you can come to informed, supported, and achievable solutions to complex challenges. Given that water quality is an important factor when it comes to obtaining permits, our consultants are able to assist you during that part of the process as well.
