Several reports of waterborne pathogens have increased in the past recent years, including parasites from fecal and environmental sources. Several factors contribute to the emergence of waterborne parasites as follows: o Changes in human demographics o Changes in human behavior o Changes in pathogen dynamics o Changes in agricultural practices o Poor surveillance and monitoring systems Philippines is facing issues with availability of clean water and this is mainly due to factors such as, growing population, irrigation needs, rapid industrialization and urbanization, particularly in rural areas. As evidence, in 2004, 5.5% deaths were reported due to water, sanitation and hygiene-related causes. Following this, the Philippines Development Plan 2011–2016 calls for additional infrastructure investments in water, to be able to meet the growing demand (UN Waters). However, there is scarcity of reported data on waterborne parasites in the country. Therefore, this study aims at monitoring the surface water in the seven lakes of San Pablo intended for recreational and aquaculture purposes for the presence of a range of waterborne parasites. This will be the first study to determine parasite contamination in the seven lakes of San Pablo, Laguna. Obtained data will be used to provide estimates of the risk factors to human and environmental health.
