6.2. Reasons for failing good quantitative status
There are five reasons for failing good quantitative status and are summarised in the Table 6.1 below.
About 40% of the RBDs (43% = 57 of 135 reported RBDs), where information is available are failing good quantitative status of groundwater bodies.
The main reason for failing good quantitative status is the exceedance of the available groundwater resource by the long-term annual average rate of abstraction that may result in a decrease of groundwater levels.
