Kleinfelder was asked to use its wealth of experience derived from working in the U.S. to help Peru develop water quality regulations. Peru is the world’s leading producer of silver and second largest producer of copper and zinc, so mining plays an important role in the Peruvian economy.
Kleinfelder developed a five-phase program incorporating concepts of existing effluent quality (EEQ), definition of appropriate BMPs and treatment technology, completion of water quality assessments/TMDLs, and elements for a permitting and continuing monitoring program. The seminars were well attended by a wide variety of government personnel, ranging from permit writers to the Minister of MINAM himself.
