The Regional Chronic Endemic Hydroarsenicism (HACRE) was produced for the study of arsenic (As) as contaminant of waters. The presence of arsenic in drinking water is commonly associated with cancer skin and several other diseases. Is a necessary warrant this contaminant detection in order to make the relevant health safety measures. In this study we evaluated the presence of As in 12 water samples from regions of central Argentine: Catamarca, La Rioja, Córdoba, San Luis and Buenos Aires, including some of this for first time. Spectrophotometric method was used to Vasak-Sedivek, the laboratory of Toxicology and Legal Chemistry successfully passed two quality controls CEPIS (Panamerican Center for Sanitary Engineering and Environmental Sciences)/ PAHO (Panamerican Health Organization)/ World Health Organization (WHO). Results were found in the range concentration: 0.0125 to 0.06 ppm. WHO and the Argentine Food Code advise a limit value 0.01 ppm for drinking water. The results indicated that all the samples overcome the suggested values, then we try to continue doing this monitoring and study on affected areas, this information bring the opportunity to As removal activities that could help to normal As levels permitting a compatible good quality of life. It is noted that in this work were harmonized research, teaching, community service and collaboration
