A European Commission Staff Working Document published on 23 July 2026 assesses Malta's implementation of the Nitrates Directive (91/676/EEC) for 2020-2023, finding that 68.2% of groundwater monitoring points exceed the 50 mg/l nitrate limit and 79.5% are classified as hotspots. The document recommends reinforcing the national action programme, closing data gaps on nutrient balances, and improving enforcement to address widespread pollution.
The report covers Malta's entire territory, designated as a nitrate vulnerable zone since 2003 with a mandatory action programme last amended in 2018. During 2020-2023, no further amendments were made. The document highlights that high livestock density (3.27 livestock units per hectare, far above the EU average) and missing nutrient balance data complicate pollution control. Groundwater shows increasing trends at 80% of monitoring points, while surface water hotspots affect 15% of points, with 100% of rivers and 50% of lakes/reservoirs classified as eutrophic. Long groundwater residence time (over 40 years) means current measures may take decades to show effects.
The Commission recommends reviewing and reinforcing measures to address high and increasing nitrate concentrations in groundwater and surface waters, as well as eutrophication. It calls for closing data gaps on nitrogen and phosphorus balances in reporting to Eurostat, considering limitations on phosphorus fertilisation, ensuring coherence with the Water Framework Directive, simplifying measures where possible, and promoting best practices and innovation. The document also urges increasing preparedness and resilience of action programmes under climate change.
Non-compliance issues identified include record keeping (5.6% of checks), lack of cesspit certificates (10.6%), and organic fertiliser application during prohibited periods (3.9%). The report warns that without reinforced action, Malta risks failing to meet Water Framework Directive objectives and facing further degradation of water quality.
Maltese farmers face potential stricter fertilisation rules and phosphorus limits, increasing compliance costs. National authorities must strengthen enforcement and close data gaps, requiring administrative resources. The environment and water users stand to benefit from reduced nitrate pollution over the long term. The livestock sector, with high density, may need to adjust practices to meet tighter nutrient management requirements.
Malta is expected to revise its action programme based on the recommendations. The Commission will monitor progress through future reporting cycles and may pursue infringement proceedings if measures remain insufficient.
