Biography
Extensive experience in groundwater exploration and aquifer management, aquifer recharge, karst investigations, tailings and waste rock seepage investigations, numerical modeling, mine dewatering, hydrogeological components for feasibility studies and EIA’s for new mines and dam sites, groundwater and soil remediation, geochemistry, and surface water hydrology components.
Currently Co-founder and Managing Director for FloSolutions, a new and innovative consulting group focused on water management in the Mining and Agricultural Sectors. Previously I was Global Mining Hydrogeology Sector Leader for MWH between 2008 and 2013. The MWH hydrogeology group in Lima was the largest and most diverse center for hydrogeology within MWH globally and arguably one of the largest and most diverse hydrogeological groups worldwide.
Prior to MWH I was Founder and Managing Director of Ground Water International (GWI), the largest hydrogeological consulting group in Peru between 2004 and 2008. GWI clients included Antamina, Yanacocha, Minsur, Volcan, BHP, Rio Tinto, Xstrata, Newmont, Teck, Gold Fields, and Barrick. At the time of acquisition by MWH in 2008, GWI had over 40 staff members from 11 countries.
Previous to MWH I was Founder and General Manager of Hydrogeological Consultants Inc. Peru S.A.C.(2002 - 2004). Although we only operated for about two years, HCI Peru worked with some of the largest mines in Peru including Antamina and Yanacocha.

Chairman of Mine Water Solutions Conference
2013-04-15
Mine Water Solutions in Extreme Environments was held in Lima, Peru in April 2012. The conference provided a forum for presentation and discussion about successful practices that enable responsible mining to be undertaken in challenging environments, while minimizing water use and/or preserving water resources. The conference was attended by over 350 delegates from 25 countries.
Keynote Speech on Risks of Mining in Karstic Regions
2013-04-16
Site selection for new mine waste facilities in some areas of Peru is extremely challenging as some regions are more vulnerable to structural deformation and karstification than others. The presentation showed the risks associated with mining in karstic regions and investigation methods which can reduce the risks.

Hypogene speleogenesis related to porphyry magmatic intrusions and its influence on subsequent karst evolution in the Peruvian high Andes
Geomorphology2022
Carbonate rocks of Cretaceous and Jurassic age are widespread in the Peruvian Andes where they host numerous magmatic intrusions and related ore deposits. Most of Peru’s metal ore deposits are located at high elevations within a narrow, tectonized carbonate-rock belt extending over 2,000 km in length. Many of the limestone formations are karstified and characterized by high recharge and percolation rates, well-developed subsurface drainage and complex flow patterns. Knowledge of karst in the Andes is generally limited, although karst is recognized to cause extreme hydrogeologic complexity and great challenges in development of mining facilities located in carbonate settings. Aspects of the origin of void/conduit systems (i.e. speleogenesis) and karst evolution are rarely addressed in environmental impact and risk assessment studies.
