There is also a risk that with anticipated chemical use (aluminum sulfate) the wastewater treatment sludge potentially adversely affects the sludge stored on the BSCWSD property


Alum should cause no issues with the sludge stored on BSCWSD property. However, to the reviewers point, the effect of the additional aluminum on the compost quality should be considered. It may warrant utilization of a different phosphorus adsorbing coagulant with more beneficial land application qualities (such as ferric-based metal salt coagulants). This will be added to the CDR Final Draft.
