Ondrup Mose Miniwetland, Odder Stream (AU)

Demonstration Site – Denmark (Ondrup Mose Miniwetland, Odder Stream)

Wetlands and watercourses as natural filters for agricultural contaminants
The Danish site, located between the Ondrup Mose wetland and the Odder stream, serves as a pilot area for studying the effectiveness of natural systems in retaining nutrients and pollutants originating from agriculture.

Ongoing activities:

  • Maintenance of the area and installation of instruments for real-time monitoring of water flow and climatic parameters
  • Water quality analysis and initial sampling to test environmental DNA/RNA detection methods
  • Start of continuous monitoring (from August 2025) with meteorological data collection and the use of sensors—including low-cost ones currently under evaluation.

Seasonal and sediment monitoring:

  • Seasonal sampling for eDNA/RNA, pesticides, and organic micropollutants, calibrated according to the agricultural calendar (e.g., fertilization, treatments)
  • Collection of sediment and porous material samples from different site zones to evaluate long-term accumulation of nutrients and contaminants

Objectives:

  • Explore the role of natural and artificial wetlands in retaining agricultural contaminants
  • Assess efficient and scalable monitoring strategies, including economical sensors and environmental DNA-based techniques
  • Contribute to the design of effective ecological interventions to improve water quality in rural areas.
