“…Ravi et al [19] have studied geochemistry of groundwater quality and its evaluation in Karnataka. On the other hand, in a recent study conducted by Khan and Umar [27] in central Ganga plain suggest that groundwater is contaminated due to indiscriminate disposal of coal fly. They also found the presence of arsenic mineral phases in agricultural soil samples due to the untreated release of effluents from a thermal power plant in the studied area.…”

“…There are several studies that have been conducted on groundwater quality assessment in different parts of India and many parts of the world with respect to drinking and irrigation [17][18][19][20][21][22][23][24][25][26][27]. Kaur et al [17] studied the quality of groundwater for drinking and irrigation purposes in the Malwa region, Punjab that indicates poor water quality of the region.…”

The present study confers the hydrogeochemical characteristics and groundwater quality assessment for drinking and irrigational purposes. Most of the population depends on groundwater for their daily needs especially for drinking, irrigation, and industrial purposes. For this reason, total seventy-two groundwater samples have been collected from different parts of Ghaziabad district for the pre-and post-monsoon in the year 2016 and analyzed for water quality parameters such as pH, electrical conductivity, total dissolved solids, total hardness, bicarbonate (HCO 3 −), carbonate (CO 3 2−), chloride (Cl −), sulphate (SO 4 2−), fluoride (F −), calcium (Ca 2+), magnesium (Mg 2+), sodium (Na +), and potassium (K +). Results show that the water samples of the study area are generally hard to very hard and slightly acidic to alkaline in nature. Results also suggest that chloride (Cl −) ions dominate over SO 4 2− ions, whereas HCO 3 − ions dominate over Cl − and SO 4 2− in the studied groundwater samples during the pre-and post-monsoon periods. The Piper trilinear diagram of groundwater shows that dominant facies is Na +-HCO 3 − type in both the monsoon periods. The nitrate concentration in the groundwater samples varies from 22 to 293 mg/l in the pre-monsoon, of which 83% of groundwater samples are not recommended for drinking with reference to the concentration of nitrate. Base-exchange indices classified 89% and 11% of the water sources as the Na-HCO 3 type and Na-SO 4 during the pre-and post-monsoon seasons, respectively. According to the meteoric genesis indices, 89% and 11% of the water sources as shallow meteoric water percolation and deep meteoric water percolation type during the pre-and post-monsoon periods, respectively. Furthermore, most of the groundwater samples are found mainly influenced by rock dominance according to Gibbs diagram plots.

“…20 Thus, disposal of huge amount of coal fly ash leads to the release of toxic elements which in turn contaminate soil and groundwater resulting in a potential environmental hazard and great effect on the environment throughout the globe. The extensive amount of coal fly ash imposes serious environmental threat 23 . The human health may be negatively influenced by leachate and its noxious compounds in the vicinity of a coal fly ash landfill site [23][24][25] and some studies have shown that leachate produced by landfills can be toxic to groundwater, and even to humans in the proximity to the landfill.…”

“…When we improve the quality of the soil (e.g., improving soil structure, increasing the SOM pool, improving soil fertility), we decrease risks of soil degradation (chemical, physical, biological, and ecological), and, as a consequence, we improve environmental quality (Ahmed, Qureshi, Nergis, & Shareef, ; Khan & Umar, ; Lal, ). Academics and technicians have created products to minimize soil erosion and to avoid or control the occurrence of invasive plants, some successfully, others unsuccessfully (Jiang, Liu, Zhang, Zhang, & Wang, ; Keesstra et al., ).…”

Soil erosion and the invasion of exotic plant species are major constraints to achieve sustainable development around the world. Currently, we find few products devoted concomitantly to combatting soil erosion as well as the establishment of unwanted exotic plants. In this paper, we introduce a new product, called herein a bioblanket, that protects the soil and impedes the establishment of exotic plant species. This product is of simple design, and to manufacture it, we use two biodegradable materials: jute tissue and grass wastes. We designed this product to combat soil erosion and the germination and establishment of new, unwanted, invasive plant species. In this paper, we describe our evaluation of how successful this product was in terms of improving the chemical attributes of soil. We also identified the product's potentialities and weaknesses by means of strengths, weaknesses, opportunities, and threats (SWOT) analysis. The bioblanket ameliorated the chemical attributes of the soil, as evidenced especially by the neutralization of acidity (8.5%) and aluminum toxicity (33%), and by an increment in nutrients concentration. We argue that after adequate treatment and management, the residues of plants that are normally considered unwanted materials can be transformed into a raw material to control the propagation of unwanted plant species, and concomitantly control soil erosion while improving the chemical conditions of the soil. The improvement of the soil chemical attributes was one of the main positive effects reported through the SWOT analysis. In addition, the SWOT analysis revealed some features that need improvement in future generations of the product, but we argue that these features do not impede the benefits for the use of the product in its present form.
