Abstract: This work was developed in two stages, in the first one the technical literature was analyzed for the solution of the problem, where two techniques were evidenced, namely: (a) Multiphasic removal - Removing (not necessarily dispatching) the contaminated water, where we can already split it into a low contaminated part and a persistent agents contaminated part. (b) Bioremediation - At this stage are added Mono ammonium phosphate, ammonium sulfate and calico hydroxide for the local biological agents to counter the persistent BTEX's, PAH's and HTP's, into the most contaminated part of the collected waters. Secondly, these techniques were applied to a site contaminated by petroleum hydrocarbons in the municipality of Estância de Socorro, in the interior of the state of São Paulo - Brazil. This application was carried out in two stages, the first one started in 2010 and ended in 2013, the multiphasic removal technique was used, where most of the contaminants were removed and the process was interrupted, but not the monitoring. In the year 2014, it was observed that some contaminants still persisted and it was decided to apply the technique of induced bioremediation at the site, during the period from 2014 to 2017, when the analyzes of the groundwater showed the disappearance of the other contaminants. This work aims to show the technical and economic feasibility in the removal of the contaminants studied, as well as to encourage the practice of the processes used.
