The Environmental Science Program, Faculty of Science and Technology, Nakhon Si Thammarat Rajabhat University, has signed a Memorandum of Agreement (MOA) on Research and Academic Service Collaboration with the Bang Khan Subdistrict Administrative Organization for the Community Forest Management Project in Ban Phru Toei.

Under this collaboration, the Environmental Science Program conducted a study on the surface water quality within the Ban Phru Toei community forest area, located in Bang Khan Subdistrict, Bang Khan District, Nakhon Si Thammarat Province. Water samples were collected from five locations within the community forest over a three-month period to analyze three aspects of water quality: physical, chemical, and biological.

📊 Findings

Physical Quality

All sampling points satisfied the standard surface water quality criteria.

Chemical Quality

The pH, hardness, and dissolved oxygen (DO) levels at Points 1, 2, 3, and 5 (in February) were within standard limits. However, Points 4 and 5 (in January and March) recorded DO levels below the standard due to stagnant water and the decomposition of organic matter, leading to reduced oxygen levels.

Biological Quality

• Point 1 (Upstream area): Very clean water
• Point 2 (Waterfall area): Very clean water
• Point 3 (Near the dam inlet): Very clean water
• Point 4 (Downstream area): Clean water
• Point 5 (Phru Toei Canal): Polluted water

The Environmental Science Program notified the Bang Khan Subdistrict Administrative Organization of these findings to assist in assessing and improving surface water quality in the area. The results aim to support planning and development initiatives focused on maintaining appropriate water quality standards for sustainable community use.
