El Salvador's environment and natural resources ministry (Marn) has received the results of a study carried out by environmental investigation and promotion agency IPA to evaluate contamination of the Sucio river in La Libertad department.
The studies, partly funded by the Fund of the Initiative for the Americas El Salvador (Fiaes), were conducted on five points along the river where metals and domestic and industrial waste are dumped.
The studies revealed that the water contains dangerous metals such as mercury, Marn said in a release.
The ministry plans to use the results of the study to develop policies and laws to preserve the river.
Only around 2% of the water in El Salvador's rivers is apt for human consumption.
