“…Additionally, organic matter increased as the irrigation was increased with benefits to the soil (Wang et al, 2007;Walker and lin, 2007;Rusan et al, 2007). According to Galavi et al (2010) organic carbon (OC) % increased significantly (p ≤ 0.05) and total carbon (TC) increased up to 7% (Alrajhi, 2015;Jiajie, 2013) after wastewater irrigation. Also, Abegunrin (2016) found that wastewater irrigation caused an increase of hydrophobicity in subsoil.…”

“…When SL and LS soils were compared for the same treatment, total N% was statistically significant only in control treatment (Wα Vs Wβ) (p  0.032) (see Yable 7). Qian and Mecham (2005), Galavi et al (2010), Bali et al (2011), Abegunrin (2016), and Jiajie (2013) found that during irrigation with wastewater there was a significant increase in total N % (p ≤ 0.05) and according to Alrajhi (2015) total N% increased by 4 %. This could be explained by the fact that wastewater addition to soil increases nitrogen concentration (Monnett et al, 1996;Fuentes et al, 2002;Cooper et al, 2015) which could be attributed to urea and nitrogen contained in the urban wastewater (Bernala et al, 2006;Fonseca et al, 2005a).…”

<p>In order to study the chemical parameters of the soil after sub-irrigation with wastewater, a system was installed in one of the greenhouses of the Agricultural University of Athens. Wastewater was applied subsurface into the soil mass of the pots were used. Three treatments were used: Untreated wastewater (U), Treated wastewater (T) and tap water (W) as control. Two different types were used: Soil (a) characterized as Sandy loam and soil (b) characterized as Loamy sand. Moreover, in order to investigate the change of total Nitrogen and organic matter concentrations at the point where the emitter was placed, the soil mass was divided into two zones. The upper (zone I) and the lower one (zone II). The total nitrogen content, ammonia nitrogen (NH4-N), nitrogen nitrate (NO3-N) and the percentage of organic matter, were determined in the soil samples. Statistically significant differences (p <0, 05) were observed in the organic matter and the total N%, only for soil (b). For soil (a), organic matter percentage was increased in zone (I) (irrigation with treated wastewater at 20 cm depth). For soil (b), total N% was increased in zone (I), while nitrate and ammonium were increased in zone (II) (irrigation with untreated wastewater at 20 cm depth).</p>

Groundwater acts as a lifeline in the coastal regions to meet out the domestic, drinking, irrigational and industrial needs. To investigate the hydrogeochemical characteristics of groundwater and its suitability, twenty samples were collected from the shallow tubewells of study area having screen depth 21-54 m. The water quality assessment has been carried out by evaluating the physicochemical parameters such as temperature, pH, EC, TDS and major ions i.e., Na -, respectively and Na-Cl-HCO 3 is the dominant groundwater type. The analyzed samples were also characterized with different indices, diagram and permissible limit i.e., electric conductivity (EC), total dissolved solids (TDS), chloride content (Cl), soluble sodium percentage (SSP), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), magnesium adsorption ratio (MAR), Kelley's ratio (KR), Wilcox diagram and USSL diagram, and results showed that groundwater are not suitable for drinking and irrigational use. The factors responsible for the geochemical characterization were also attempted by using standard plot and it was found that mixing of seawater with entrapped water plays a significant role in the study area.

In view of changes in the water environment in Songnen Plain and water quality problems in recent years, the Second Songhua River Basin was used as our research object. To conduct the water environment investigations, 11 surface water samples and 76 shallow groundwater samples were collected. Multiple methods, such as isotope hydrological analysis, principal component analysis, and irrigation water quality parameter (SSP, SAR, RSC, MAR, KR) analysis were used to systematically apply water chemistry analysis and its evolutionary process, and water quality evaluation for irrigation. The results showed that Ca 2+ and HCO 3 were the main ions in the water body. The regional groundwater was recharged by atmospheric precipitation, and the surface water received both atmospheric precipitation and groundwater recharge. The hydrogeological process included the weathering and dissolution of carbonates, and the ion exchange reaction. In addition, the major reaction of local groundwater was the weathering and dissolution of silicate. Water quality was affected by agricultural fertilizer and domestic sewage. The water downstream of the basin, if used for irrigation, might accelerate the formation of alkaline and saline soil, neither of which help crop growth. The water upstream of the watershed in the region was suitable for irrigation.Keywords: chemical information of water, statistical analysis, isotope hydrology, assessment of irrigation water *
