Research findings and examples of application to real problems--When can natural processes to reduce, or even destroy, contaminants at toxic waste sites be relied on?
Nitrate from fertilizer is degraded by microbial action in the presence of solid minerals. This helps mitigate the effect of the nitrate, but begins to diminish the solid minerals needed. Will the process be sustainable in the long term?
