| IMPACT | DESCRIPTION OF THE RISK |
|---|---|
| L | Groundwater level decrease (aquifer depth, water volume) due to extractions. |
| N | Nutrient pollution, mainly from fertilizers and animal waste, above the legal limit (50 mg/l) or close to the limit with an upward trend. |
| C | Chemical pollution other than nutrients (mainly pesticides but also metals, hydrocarbons, etc.) above the legal limit or close and with an upward trend. |
| E | Impact on terrestrial ecosystems dependent on groundwater. |
| M | Microbiological contamination. |
| O | Organic contamination. |
| IMPACT | DESCRIPTION OF THE RISK |

| S | Saline intrusion or contamination. |
| T | Other types of significant impact. |
| N | No significant impact. |
| A | Acidification of water bodies. |
