| Staff from the Dong Nai Center for Disease Control and Prevention are taking water samples at Le Quang Dinh Secondary School (Tam Hiep Ward) for quality testing. |
For a densely populated industrial city like Dong Nai, with its rapid urbanization rate, ensuring access to clean water for its residents is not simply a matter of infrastructure investment, but also a challenge related to quality management, water resource protection, and changing community water usage habits.
There are still worrying "gaps".
In 2025, the Dong Nai Center for Disease Control (CDC), in coordination with regional health centers, health stations, and the Center for Technical Standards and Quality Measurement 3 (National Accreditation Office), conducted external quality checks of clean water at 96 water supply units across the city, testing 242 samples. The results showed that 116 samples met the national technical standards for clean water quality for domestic use.
Notably, there is a significant disparity in compliance levels among water supply models. While large-scale water treatment plants and enterprises achieved 91 out of 117 standard-compliant samples, the group of water supply facilities with a capacity of less than 1,000 m³/day only had 25 out of 125 samples meeting the standards. This means that in many rural and remote areas, people are still facing the risk of using unsafe water sources.
According to Mr. Luong Truong Vinh, Head of the Environmental Health - School Health Department (CDC Dong Nai), water supply systems managed and operated by cooperatives/commune People's Committees are common in many rural areas, but monitoring showed that only 3 out of 47 samples met the standards. Up to 20 out of 23 water supply units in this group had samples that did not meet the standards. This is not just a purely technical issue, but a public health issue. Unsafe drinking water can lead to risks of intestinal diseases, skin conditions, infections, and long-term exposure to heavy metals.
