This study provided data for the evaluation of some of the methods currently in use for the determination of minerals in water. The study also indicated the degree of accuracy and precision obtainable when many laboratories participate and a variety of methods are used. Nitrate determinations were the least accurate, and the nitrite measurement was only slightly better than the nitrate. Other determinations showed substantial improvement over the results of earlier studies. With the exception of the nitrogen measurements, overall precision and accuracy are excellent, especially for so large a number of participants working with so wide a choice of methods.
