| Abstract |
Pairs of synthetic water samples were prepared in three ranges of concentration for pH, specific conductance, total dissolved solids total hardness, sodium, potassium, total acidity/alkalinity, chloride and sulfate for analysis by FWPCA Official Interim Methods for Chemical Analysis of Surface Waters. Fifty-one analysts from twenty laboratories in FWPCA and 5 non-FWPCA laboratories cooperated in this study. A statistical summary of the results indicates the precision and accuracy values obtainable in routine work. |
