Study of impact on water quality: physical and chemicalA case study of water sprang the arboretum Lao Nong Chang District Community Compared with the standard of surface water quality By survey and water samples were 3 points per point 3 repeat is water sprang the Lao watershed area (position, pop)The distance from the upstream 50 meters (points to play in the water), and the distance from the upstream 100 meters (after the player points which divide to keep water) is 3 times is the first festival. During Songkran Festival, and after the parameters measured were temperature, pH,Dissolved oxygen, BOD, turbidity, total dissolved solids and total suspended solid, electrical conductivity, fat and oil. The results showed that the first. During and after the temperature is in the range 24.4 Festival - 27.4 degrees Celsius temperature such as natural environment The pH in the range 6.74-6.9 which such value standard is 5.0-9.0 oxygen dissolve in the 4.24-5.29 mg / L standard, which specified is less than 4 mg / BOD in the 0.96-2.11 mg / l found ว่าช loss Songkran distance from the upstream 50 meters. (points to play in the water) is 2.11 mg / L and the distance from the upstream 100 meters were 2.09 mg / L, which set higher standard than 2 mg / L It is also found that the dissolved solids suspended solids and turbidity was high due to the tourists played down the water Festival a lot.Tourism activities during the festival resulted in water quality changes compared to the distance away from the upstream, it can be seen that the tourists traveled activities occur.
