Evaluation of pH and EC changes in wastewater application in different depths of soil
Journal Title: Journal of Research in Ecology - Year 2016, Vol 4, Issue 2
Abstract
Scarcity of water as well as scarcity for food production and environmental protection in the world have forced human beings to seek new water sources. Nowadays, application of unconventional water resources (wastewater) have been proposed in the countries facing shortage of water resources. However, minimal studies have been focused on this issue. The present study evaluated changes in the elements of the soil irrigated with wastewater. For this purpose, an experiment was conducted as a randomized complete block design with three replications. Soil samples were collected from the studied regions at the two depths of 0-30 cm and 30-60 cm. Studied parameters included acidity (pH) and Electrical Conductivity (EC) of the soil. Three regions were taken into consideration for the study such as no irrigation, irrigation with treated wastewater and irrigation with river waters. The results showed an increase in pH of the effluent from Zahedan wastewater treatment plant compared to the control. However, electrical conductivity decreased in the soil irrigated with wastewater
