02 · CASE IMPACTS AND RESPONSIBILITY
Environment · People · Accountability
Environmental
The underlying case concerns polluted water and possible soil/groundwater impacts. The 20 August update shows road grading and drainage construction, but does not show that environmental clean-up and testing are complete.
People & health
The road works affect everyday access for Kassapa, Kamatete and Kamisepe. Earlier case records also raise concerns about homes, water, health and livelihoods that remain relevant to follow-up.
Company & government accountability
Road rehabilitation is visible. AMAP still needs clear records on environmental clean-up, post-incident soil/water testing, monitoring, regulatory compliance, assistance and compensation.
