Note that particle-size distribution does not form part of the recommended acceptance criteria. While this information may be useful in designing blends, the disconnect between hydraulic conductivity and the uniformity of gradation makes it far less important than measuring the hydraulic conductivity directly<ref>CRC for Water Sensitive Cities.
