Petroecuador and local authorities tried to contain the oil slick with a boom. Nonetheless, some of the oil entered the Napo river, which flows across the border into Peru.

The released oil slick contaminated the drinking water supplies of the City of Coca. It was reported that about 60,000 people had to get water delivered by 65 tankers.

Freshwater (e.g. pond, lake, stream)

The crude oil released from the pipeline rupture entered the Coca river and then discharged into the Napa river.

The laying of pipelines in areas with potentially unstable soil should be avoided, where possible.

In general, pipelines should be fitted with adequate mechanical protection coupled with stress monitoring to mitigate the impact of slow landslides. No mitigation measures for the impact of rapid, catastrophic landslides on pipelines exist. In this case, only costly pipeline relocation or slope stabilisation can mitigate the risk.
