The following study seeks to determine the hazard of bacterial contamination, due to the interaction of the method of aquifer vulnerability "GOD" and total coliform bacterial pollution load .By developing cartographic maps. By implementing this study we look to contribute to the preservation of the quality of the aquifer Chillon, which is used as a source of water for the population of Lima. Knowing the aquifer vulnerability to be negatively impacted by anthropogenic activities can develop appropriate management in land use and water. The district of San Martin de Porres has locations without access to public water, so the population uses water from underground wells for personal hygiene or daily consumption. Also, the lack of drainage system has caused the population uses cesspits, latrines as silos and systems of excreta disposal. There is a chance of leakage of water from the River Rimac and Chillon, generating a diverse source of contamination to the aquifer. Wells was found in a state of neglect, which was not properly closed, exposing the water to direct contamination. This geographical location of the district of San Martin de Porres is added, which is bounded on the north by the Rimac River and on the south by the Chillon River, both rivers recharge the groundwater by water leaks that occur through its bed, this being a major source of aquifer contamination. For this thesis, information was gathered from public institutions such as the National Water Authority (ANA), SEDAPAL and MINSA. Getting information about the ANA of 81 inventoried wells, of which 14 underground wells in the San Martin de Porres, by reference to their spatial distribution in the cartographic map of the district were selected. The GOD method is the product of three variables: G (Grade hydraulic confinement, O (Occurrence of the substrate) and D (depth of the aquifer). The first variable of the method was the degree of hydraulic confinement, which was obtained from previous research in the area of study, indicating that the district of San Martin de Porres is an unconfined aquifer, obtaining the value of 1.0 in the GOD application method. [26] The second variable is the occurrence of the overlying substrate, which was obtained from the National Hydro geological Map and Map of District Boundaries. The district of San Martin de Porres has two types of formations: Qh-c permeable detrital Formation generally unconsolidated and Training JSKI-vs. local aquifers (detrital or cracked) or groundwater regions without appreciable amount. The Qh-c formation consists of alluvial sands with an index of 0.7 for an unconsolidated lithology and JSKI-vs. formation consists of shales with an index of 0.5 for a consolidated lithology (porous rock). [13] The latter variable is the depth of the water, which was obtained by using a water level sensor in the selected wells 14, obtaining values between 3.5 m and 22 m. depth, corresponding GOD method according to indexes between 0.7 and 0.9. [8] The product of the three variables of GOD method selected well in each resulted in an index of medium and high vulnerability. Which is plotted on a map of aquifer vulnerability on a scale of 1: 50,000. Determining the Total Coliform pollution load in groundwater was conducted at the Laboratory of the Executive Office of Environmental Health – Health Directorate V Lima Ciudad, where results of low, moderate and high pollutant loads was obtained. The hazard of bacterial contamination for total coliforms district throws a high probability of distress in a 60.54% and 39.46% in intermediate. These results demonstrate the need to develop a Management Plan for Water Resources with adequate protection of groundwater wells.
