Land application of drinking water treatment residuals to
reduce phosphorus (P) from agricultural land could provide
economic and environmental benefits to municipalities and
communities by preserving surface water quality. Only treatment
residuals that have significant P sorption capacity will reduce
runoff P, and the ability of different treatment residuals from
different plants to reduce P runoff varies greatly.
The authors describe a simple test that can determine
whether a treatment residual will serve as a P sorbent and the
relative amount that should be land-applied. Currently, most
utilities are landfilling their treatment residuals. Utility managers
will be interested in land application of their residuals because it
will decrease their waste-disposal expenses, and it may help
protect their source water from agricultural runoff. The major
stumbling block for utilities is obtaining permits for land application.
However, predicting the performance of a given treatment
residual to reduce runoff P is necessary to obtain permits from
regulatory agencies. Includes 36 references, tables, figures.
