Abstract: To ensure the quality and quantity of soil and water resources over time is necessary to establish a continuous monitoring system on them, which means balancing the exploitation of the resource in terms of quantity, quality and relation to other natural resources. The characterization included sample collection water and soil in oil exploration areas of Anzoategui, Venezuela, during the period between 2009 and 2013. In surface waters, the phosphorus and nitrogen concentrations were below the limits set out in Article 10 of Decree 883, the suspended solids exceeded the limit of the standard in 2009, Oils and Fats Minerals and Hydrocarbons, Biochemical Oxyen Demand and Chemical Oxygen Demand exceeded the limit in the years between 2009 and 2013. In soils under treatment found that metals and oils and yielded the highest concentration in 2012, concentrations of metals and hydrocarbons were higher compared to soil samples adjacent to spills. It concludes that the temporal variability of the water is greater than that of the soil.
