ABSTRACT: The objective of this work is to describe a project-based learning experience carried out with students of an assistant training course. Students had to design a project to establish nitrate contamination of bottled water, analyse the reasons why people consume bottled water and their perception about its quality. For this purpose, a survey and a sampling plan was planned and executed. The survey was answered by 364 people. A total of 200 samples were obtained from 20-liter containers. Results were discussed and presented in a scientific reunion. Strategies to employ the data obtained and the methodology used in undergraduate courses were proposed.
