Hypothesis
How can an armored geomembrane cover system effectively prevent stormwater infiltration to contaminated rock?
Conclusion
The armored geomembrane cover system successfully prevents stormwater infiltration to pyrite-bearing rocks, mitigating surface and groundwater contamination.
Supporting Evidence
- The cover system was designed to prevent Acid Rock Drainage (ARD) from pyrite-bearing rock.
- The project involved a significant engineering effort to address the unique challenges of steep slopes.
- Geocells and geogrids were used to support the armor system without penetrating the geomembrane.
Takeaway
This study shows how a special cover made of strong plastic can stop rainwater from getting into bad rocks, which helps keep our water clean.
Methodology
The study involved designing and constructing a geomembrane cover system using geocells and geogrids to support stone aggregate armor on steep slopes.
Limitations
The design was constrained by the need for no penetrations through the geomembrane and the steepness of the slopes.
