A surface water (biopolymers!) subjected to flocculation (deduciblefrom ratio humics/building blocks). ·Site B： A very unusual water， because biopolymers are extremely high (650 ppb). Such valuesare normally only found for waste waters or shallow lakes with reed. ·Site C： Also remarkable： Low in DOC (<1 ppm) but-on a relative scale-high biopolymers. ·Site D： DOC <100 ppb! Such waters are usually very old and come from deep wells. Such watersmay also be found in shallow depth in areas of recent volcanic activities. Volcanic matteris a strong absorbent for DOC. ·Site E： Similar to Site D. 应用实例：饮用水的检测3 Further examples of Chinese Tapwaters， here with OND included ·Site F： Extremely high in DOC (6 ppm). High in Biopolymers and LMW Neutrals. Biopolymerscontain about 50 % proteinic matter (high OND/DOC ratio). A Surface water subjected toflocculation and chlorination. High in Nitrate (> 30 ppm) and even ammonium. ·Site G： Low in DOC (about 1 ppm)， but very high in nitrate (> 20 ppm). This is remarkable asnitrate from agricultural activity usually correlates with high DOC.
