Coalbed methane (CBM) or coalbed natural gas (CBNG) is an unconventional natural gas resource with large reserves in the United States (US) and worldwide. Production is limited by challenges in the management of large volumes of produced water. Due to salinity of CBM produced water, it is commonly reinjected into the subsurface for disposal. Utilization of this nontraditional water source is hi...

In this paper, the reuse of reclaimed wastewater for irrigation of agricultural land and its effect on soil quality has been investigated in an arid region of Iran. For this purpose, two pilots of 2,000 m2 area with a variety of plants were selected near the effluent discharge of a wastewater treatment plant (WWTP) in Zahedan and Zabol cities in Sistan and Baluchestan Province. The wastewater t...

The byproducts of flue gas desulfurization (BFGD) are a useful external source of Ca(2+) for the reclamation of sodic soils because they are comparatively cheap, generally available and have high gypsum content. The ion solution composition of sodic soils also plays an important role in the reclamation process. The effect of BFGD on the soluble salts composition and chemical properties of sodic...

Over 90% of the water supplied in the coastal region in Israel in 2013 (600 Mm(3) y(-1)) will be from desalination plants. The wastewater generated from this water (>400 Mm(3) y(-1)) is planned, after proper treatment, to be reused for agricultural irrigation, making this low-salinity water the main agricultural-sector future water source. In this respect both the Mg(2 + ) concentration and the...

The main purpose of the current research is comparing the results of Artificial Neural Network (ANN) with Adaptive Neuro-Fuzzy Inference System (ANFIS) with regard to determination of the importance of soil properties affecting clay dispersibility. After taking samples from two depths of 0-40 and 40-80 cm, the spontaneous and mechanical dispersions of clay were recorded using both weighing and ...

Abstract The raw water for irrigation must meet the minimum requirements of class IV quality. This study aims at presenting a quality assessment several sources in Bintan Island purposes. methods used are Standardized Precipitation Index, Pollution and Sodium Adsorption Ratio. A climate analysis showed that potential high risk flood was 16 events 22 years, severe-to-extreme dry soil moisture st...

This study highlights the groundwater hydrogeochemical characteristics and processes (hydrochemistry characteristics, ion exchange, salinization) quality suitability assessment for irrigation purposes from five wells in Greenbelt area located northwestern Al-Najaf Governorate, Iraq. The of was assessed based on water index (IWQI) thirteen parameters indices such as total dissolved solids (TDS),...

Groundwater is an essential resource for drinking and agricultural purposes in the Al-Jouf region, Saudi Arabia. The main objective of this study to assess groundwater quality irrigation region. Physicochemical characteristics were determined, including total dissolved solids (TDS), pH, electric conductivity (EC), hardness, various anions cations. index (WQI) was calculated determine suitabilit...

Oil and gas drilling operations use drilling fluids (mud) to lubricate the drill bit and stem, transport formation cuttings to the surface, and seal off porous geologic formations. Following completion of the well, waste drilling fluid is often applied to cropland. We studied potential changes in soil compaction as indicated by cone penetration resistance, pH, electrical conductivity (EC(e)), s...
