Within the framework of Guatemala’s national Water and Sanitation Emergency Plan, the Ministry of Public Health and Social Assistance delivered portable laboratory equipment to nine of the departments affected by Tropical Storm Stan last October. The equipment will be used for water quality surveillance and control. The affected communities will receive training on how to use the equipment to guarantee safe drinking water. Although this laboratory equipment was purchased to deal with the consequences of Tropical Storm Stan, it will also help these communities in other water quality initiatives that have been underway for several years.
