Come and take part in water quality test – and find out how safe your water is!

U Cafe Hoi An has carried out several water quality tests at its facilities and the River Hoai since its opening in 2011. These checks are an important part of U Cafe’s eco-social commitments to people in Hoi An, Quang Nam and Viet Nam. U Cafe’s ponds are filled with clean water that has been treated through the ecological wastewater system set up inside the Cafe. Regular water quality tests have proven its quality.

These water quality checks will be broadened this year, to include other rivers and water wells in Hoi An, on a regular basis from April 2015 until March 2016. People interested in environmental conservation will be able to participate and to check the quality of the water. The test results will be published and will form a foundation for ecological projects in the future.

Residents, students from universities and high-schools, officials and employees of government and NGOs interested in environmental conservation are invited to join the project. Priority will be given to applicants who are able to attend 2 workshops and the following 5 days listed below.

The first 2 workshops at U Cafe Hoi An will introduce the project where you can also learn how to use the testing kit.
