Note: ① NTU in the table stands for Nephelometric Turbidity Unit. ② Special circumstances include source water limitations, etc. ③ CFU stands for Colony Forming Unit. ④ The values for radioactive indicators are not limits but reference levels. When radioactive indicators exceed the values specified in Table 2-1, nuclide analysis and evaluation must be conducted to determine whether the water is drinkable. | ||
