This program aims to provide safe and reliable drinking water sources to people in rural communities through long-term solutions. In order to know the current status of drinking water from different coastal areas in Davao del Sur, this project will assess the drinking water quality from community water systems. Testing the quality of drinking water from low-income communities without no connection to local water utilities agencies will be prioritized. For many rural areas, community water systems such as piped water tube wells, boreholes, and dug wells are one of the sources of drinking water. This project will test the physical and chemical quality, inorganic chemical parameters, and microbiological quality of drinking water from these community water systems ensuring the community’s access to clean water. Since these are coastal areas, excessive withdrawal of groundwater can also cause saltwater to contaminate, affecting the potability of drinking water. Thus, this project will also assess the saltwater intrusion in the different coastal areas in Davao del Sur.
