Science Project-water surveys to identify water quality around Phan. T. old Mao Yang Talat and Nong Ben Tue T. Phon Ngam Amphur kamalasai kalasin The purpose of survey and water quality by index water quality physical, chemical and biological, that can measure up to the quality and the physical condition of the water in the river and bridge, Nong Ben.
Students were surveyed by collecting water samples from the River Bridge, T. old Mao Yang Talat and Nong Ben Tue T. Phon Ngam Amphur kamalasai kalasin measured pH and the value of the amount of oxygen dissolved in water (Dissolved Oxygen: DO), and the creatures in the creature in front of the soil. During the day, 16-28 January 2559 by demarcation survey into two properties is Phan. T. old Mao Tue Yang Talat

Survey results found that Nong Ben. T. Phon Ngam Kalasin kamalasai Tue has better physical factors River Bridge, T. old Mao The rubber because the water insect Tue and aquatic plants by water with opaque Brown. Chemical factors, the average pH value and average value of 7.3 7.29 mg DO/l biological factors there are many aquatic animals. For example, the larvae of the dragonflies larval insects, cheese, pakhao, etc. As an indication of good water quality.
