Nitrate Leaching Map for Dutch Agricultural Water, 2017

RIVM created a nitrate concentration map for water leaching from agricultural parcels in the Netherlands in 2017. The map was generated using a statistical model based on data from the National Measurement Network Effects Manure Policy (LMM). It serves as an indicator for ground and surface water quality, particularly for drinking water sources.

Use Cases

• Identify regions with potential water quality problems based on nitrate leaching levels.
• Support policy discussions on where additional measures are needed to reduce nitrate leaching.
• Assess the quality of ground and surface water as a source for drinking water.

Strengths

• Map is based on a statistical model from a national measurement network (LMM).
• Explicitly indicates the map helps clarify areas where nitrate leaching may cause water quality problems.
• Provides context that nitrate is an important indicator for drinking water source quality.

Limitations

• No statements can be made about water quality at a detailed level based on this map.
• The description notes actual nitrate values can be higher or lower than the 15 mg/L reference.
• Row count, column definitions, and last update date are unknown.
