Internship Recommendation
To whom it may concern,
I am director of Hidrovia Hidrogeologia e Meio Ambiente, a Hydrogeology Consultancy founded in
1998 and located in Belo Horizonte city, Brazil. I am writing in support of Leandro K. G. Farias for
an internship.
Leandro has worked for our company as a field technician from June/2011 to January/2012,
when he left in order to pursue a university education as a Mining Engineer.
In this period, he has worked both in the field and in the office for groudwater dewatering projects
in iron and limestone mines in Minas Gerais State. He has also handled laboratory analytical
equipment for detection of water tracers.
Leandro has shown strong responsibility and commitment to the tasks assigned, as well as a
good personal integration with the team. Without hesitation, I recommend him for an internship.
Sincerely,
Gisele Kimura
