Denitrification Field Study at a Wastewater Land Application Site

Abstract

A few risks restrict the sustainable development of wastewater land application including potential nitrogen contamination to groundwater. One important component is nitrogen loss caused by denitrification in a nitrogen mass balance to control nitrogen leaching. Few field studies have been specifically conducted to investigate denitrification in wastewater land application systems. The objective of this study was to quantify denitrification at a wastewater land application site located in a semiarid area. The denitrification rate was measured within three soils at the City of Lubbock Land Application Site in three different months. One-way ANOVA and a t-test were used to compare the differences of averages of many groups of data and of two groups of data at the
