The article focuses on the impact of long-term utility of biosolids for land reclamation on surface water chemistry. Biosolids from wastewater treatment plants have been identified as profitable nutrient sources for plant growth and crop production. The microbial community and soil physical properties can also be improved by the use of biosolids. Biosolids are used to degraded soils and it has long been considered an cheap alternative to inorganic fertilizer. The use of biosolids to strip-mined land can be assumed to have both positive and negative effects on surface water chemistry. It is hypothesizes in this article that proper utility of biosolids will not cause a great effect on surface water quality. A very limited data is available on the watershed scale for biosolids. The study site described in this article is located on 6000 ha of predominantly stripmined land in Fulton County in western Illinois. Out of 6000 ha, 1790 ha of land were developed into about 80 fields for biosolids application and crop production. |
