A non-experimental research at field and laboratory was performed in order to determine organochlorine pesticides (OCPs) in soil samples from the river valley Tucutunemo Samples were taken between 25 and 30 cm deep in five locations with three replications , located approximately every 3 Km ,. The samples were dried at ambient for three days and sieved in sieve with 1 mm mesh. 2000 and ISO / IEC 17025: 6630 and methodology 99-B / C, as described in: Standard Method for the Analysis of Water and Wastewater-APHA AWWA for the determination of pesticides, the 2534 standards were used COVENIN -WPCF, issue No. 17 (1989). We considered 14 POC common of which were detected: aldrin, 4,4'-DDE and 4,4'-DDT. The rest, recorded concentrations
