Abstract [en]

This project was conducted in Pahuatlan, an indigenous community in the state Hidalgo, located in central Mexico. In Pahuatlan there is need for an improved health situation. People are frequently getting ill and problems such as diarrhoea, eye infections and skin irritation, all of which can be water related, are common, especially among the children. The foremost objective with this project was to evaluate the water quality of the drinking water in Pahuatlan and, if necessary, find solutions to provide a safe supply of drinking water. The approach was to give a multidisciplinary description of the situation, which implies that many factors are taken into consideration, including forexample natural prerequisites and socio-cultural aspects. Priorities, habits, possibility to participate, motivation and knowledge are examples of what was included in the socio-cultural investigation. The quality of the drinking water was investigated by sampling and analysis. Based on our own and earlier investigations of the water quality and the health situation in Pahuatlan the bacteriological drinking water quality needs to be improved. Most microbiological contamination is probably caused by the local population and animals and contamination routes are poorly understood by the inhabitants. The inhabitants were interested in the project and they were participating in all phases. It was easy to communicate with the people and we were accepted and respected in the community. A drinking water treatment system was implemented in one of the wells in the community. The system consists of a pump, disinfection with chlorine and a carbon filter. The system was appreciated and accepted by the inhabitants, they contributed financially and they learned how to use the equipment. According to a pilot study the equipment function satisfactorily.
