Abstract
Available data about treated sanitary and industrial wastewater in Kuwait were collected and reviewed. Potential changes in the environmental parameters of these waters when permeated through predominantly loamy sand soil samples collected from three agricultural sites in Kuwait, an arid land desert area. The environmental parameters investigated included pH, dissolved oxygen (DO), total Kjeldahl nitrogen (TKN), total organic content (TOC), and total hydrocarbon content (THC). The results indicated these parameters have generally reflected marked variations. These variations were attributed to the interactions between soil, soil pore water, and influent wastewaters used in this study. The results also indicated that the above-investigated environmental parameters stayed well within the allowable limits set for the reuse of tertiary treated sanitary and industrial wastewaters in agricultural irrigation applications.
