MONITORING BIOSOLIDS QUALITY: A STATISTICAL PERSPECTIVE

摘要

There are a number of issues that need to be considered in the design of a biosolids monitoring program to ensure the needs of generators, processors and consumers (EPA) are met. The Victorian EPA Draft Environmental Guidelines for Biosolids Management goes part the way to addressing the statistical considerations for monitoring biosolids quality, but there are other important issues for generators and processors that need to be well thought-out. These issues include defining the processor's target quality level and maximum acceptable risk of rejecting a good lot, designing an efficient sampling plan to minimise costs, adjusting significance levels when multiple contaminants are being assessed, and the need for cooperation between generators and processors.
