NH Water Resources Research Center Scholarship. 111.https://scholars.unh.edu/nh_wrrc_scholarship/111FIELD EVALUATION OF THE LAND APPLICATION OF PAPER MILL SECONDARY CLARIFIER SLUDGE  Principal Investigators: Dr. Thomas P. Ballestero, Dr. James P. Malley, Jr., Dr. George O. Estes, University of New Hampshire  Descriptors: Groundwater quality, heavy metals, industrial wastewater, infiltration, sludge Problem and Research Objectives:  Wausau Paper Company (formerly James River Corporation - Groveton, NH plant) was faced with high costs of landfilling its secondary clarifier sludge. The sludge was derived from the wastewater treatment process of paper mill process waters, and it was composed of 2% solids. The solids were basically microorganism husks, paper fibers and clay colloids. It was felt that the sludge could be land applied to grow crops suitable for forage, or in aiding with revegetation of disturbed lands. The significance of the project was specifically at saving landfill space and in sludge management. More generally, the project aided with sludge management of the regional paper mill industry. Principal Findings and Significance:  The permits were granted, wells were drilled, soil moisture equipment was installed, and the first application (2 million gallons) occurred over the middle two weeks of June. The annual application rate was controlled by the cadmium in the sludge (4 ppm). The source of the cadmium was boiler blow down water. Since that time, the site did not show much evidence of the application. At the time of this report, chemical analyses were pending.

Ballestero, Dr. James P. Malley, Jr., Dr. George O. Estes, University of New Hampshire  Descriptors: Groundwater quality, heavy metals, industrial wastewater, infiltration, sludge Research Objectives:  Monitor chemical fate and transport (soil, soil water, ground water and vegetation); characterize infiltration characteristics through time; evaluate vadose zone and ground water microbiology. Principal Findings and Significance:  This was a continuing project. The permits were granted, wells were drilled, soil moisture equipment was installed. Over the previous 18 months, over 12 million gallons were spread over the area. The annual application rate was limited by the cadmium in the sludge. The source of the cadmium was boiler blow down water. At the time of the writing, no adverse effects on the ground water were detected by measurements. Also, although the sludge had very high TKN, no nitrate increases were seen in soil water or ground water.

The source of the cadmium is boiler blow down water. To date, no adverse effects on ground water have been detected by measurements. Also, although the sludge had very high TKN, no nitrate increases were seen in soil water or ground water except immediately after the application event.
