2.2.6 Analytical Testing
Table 2.2 shows groundwater monitoring indicator system for MSWLFs.
For natural background ions and conventional indicators, all samples taken from
groundwater monitoring wells should be analyzed. For characteristic indicators,
analysis should be conducted to all site background monitoring wells and the
pollution diffusion monitoring well nearest to the landfill. Based on test reports, the
detected indicators are classified as the characteristic pollution indicators of such
landfills, and then samples of other groundwater monitoring wells are tested and
analyzed.
For indicator-specific analysis methods, please refer to groundwater sampling,
analysis, and quality control groups.
The mandatory indicators for groundwater environmental investigation into
HWLFs are as shown in Table 2.3. The optional indicators which can be found in
the List of National Hazardous Waste are screened according to the characteristic
pollutants of each waste disposal unit.
The monitoring indicator system for groundwater environmental investigation
into OCS is as shown in Table 2.4. The optional indicators can be found in the
Guidelines for Groundwater Environmental Assessment (Trial).
