Comment:
*1: We have been used NH4H2PO4 as a flocculants of the filtration from 2012-2013 season.
*2: TC=EC+OC
*3: A=1.45 times correction(EC), B=4.15 times correction(EC) and 1.17 times correction(OC).
*4: We used melted sample stored in polypropylene bottle for measurement.
*5: Fields without data should be left empty (and NOT filled with '-', 'n/a', 'NaN', -9999 or '*' etc).
