Utilization of Sewage Sludge for Terrain Stabilization in Cold Regions. Part 1.
Abstract
A terrain stabilization research/demonstration site was constructed in May 1974 at Hanover, New Hampshire, to investigate various combinations of physical, chemical and biological techniques for terrain stabilization in cold regions. Fourteen test plots (10 x 40 ft) with individual 350-gal. tanks to collect sediment were installed on a 16-deg slope. These 14 test plots were to examine the effectiveness of sewage sludge and primary effluent on terrain stabilization in cold regions. In 13 of the 14 plots the variables studied were nutrient source (fertilizer, sludge and primary wastewater), moisture (irrigated and nonirrigated), erosion control material (jute netting, straw tacked with a tacking compound, and no erosion control material) and vegetation (three grasses and to legumes). The control plot was left bare of seed, fertilizer and erosion control material for comparison. A 20,000-sq ft area adjacent to the 14 plots was installed for general testing of various combinations of tacking chemicals, plastic netting, straw, and wood fiber mulch. In general, all treatments with the exception of two plots were effective in reducing soil loss in comparison with the control which had a loss of 34,531 lb of soil (dry weight) on a per acre basis.
