Water Quality Assessment (Drinking Water Suitability)
In this phase, the focus is on evaluating whether the groundwater quality meets the requirements for safe and long-term drinking water supply. Even if sufficient quantities of water are available, the chemical and microbiological composition determines whether the source can be used directly or requires treatment and protection measures.
1. Chemical water quality
☐ Chemical analysis planned
A chemical analysis is prepared to assess the composition of the groundwater. This includes key parameters such as minerals, nutrients, and potential contaminants. The results help to determine whether treatment is required and how complex the treatment process may be.
2. Microbiological safety
☐ Microbiological analysis planned
Microbiological testing is planned to identify the presence of bacteria, viruses, or other microorganisms. These parameters are critical for public health and must be carefully controlled, especially in shallow or vulnerable aquifers.
3. Protection and vulnerability assessment
☐ Protection measures feasible
The vulnerability of the groundwater source is evaluated to determine whether effective protection zones or preventive measures can be implemented. This includes assessing surrounding land use, potential contamination pathways, and long-term safeguarding strategies.
4. Long-term usability
☐ Long-term use possible
The overall suitability of the groundwater source is assessed with a long-term perspective. This includes stability of water quality over time, resilience against environmental changes, and the sustainability of the aquifer under continuous abstraction.
