Roux Assists the Blacksmith Institute

Amanda Ludlow, Principal Scientist with Roux Associates, Inc. traveled to Peru on behalf of theBlacksmith Institute to investigate contamination from abandoned oil wells located in the hills surrounding Puno, in the communities of Pirin, Ahuallane and Huancane, located on the northwestern shores of Lake Titicaca.

 

Abandoned oil extraction wells were reported to discharge metal, oil and salt contamination into the nearby water and soil, ultimately draining to Lake Titicaca.  While many of the wells were closed and capped, residual contamination was detected in the adjacent and downgradient soil (e.g., arsenic 36,715 mg/kg).  The Peru soil cleanup standard for agriculture and residential areas is 50 mg/kg.  Immediately adjacent to the contaminated soil are potato fields, homes and a school.

Currently Roux Associates and the Blacksmith Institute are developing remediation plans for both the arsenic contaminated soil (i.e., capping and containment) as well as for the abandoned wells which continue to discharge contaminated water to the communities (i.e., constructed treatment wetlands). Construction is anticipated to begin Spring 2014.
