“…The mean value of EC was also ranged between 1919± 89.1, 1614 ± 286 and 674 ± 70.7 μS/cm for shoreline, interim and inland villages (table 6a). Similar type of finding was found in Khulna District (interim zone) for EC (100-6830 μS/cm), for pH (6.4 -7.9), respectively (Mahmud et al, 2020); temperature (27.95⁰C), EC (804 μS/cm), pH (7.7) and TDS (522ppm) in cox's bazar district (Deeba et al, 2021).…”

“…The correlation result showed some positive and negative relationship among the determined variables (table 6). The positive correlation represented the variable's homogeneous source of origin and negative correlation represented the heterogeneous source of origin (Deeba et al, 2021;Giri and Singh, 2015). The correlation between EC: TDS (r=0.712), TDS: Ca (r=0.585), DO: K (r=0.5041), Cl-: K (r=0.581), K: Ca (r=0.635) showed a strong positive relationship, that suggested the same sources of origin of variables and same anthropogenic activities or variable movement were responsible in the study area (Deeba et al, 2021;Haloi and Sarma, 2012).…”

Groundwater quality is deteriorating due to contamination of various pollutants from different anthropogenic functions and salt water intrusion in the coastal regions of Bangladesh. Three coastal villages denoted as shoreline (Rajoir), interim (Gangarampur) and inland (Ganopatipur) areas of south western coastal zone of Bangladesh were purposively selected to determine the temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), total suspended solids (TSS), dissolve oxygen (DO), total hardness (TH), chloride (Cl-), potassium (K+) and calcium (Ca++) ions. A total of 40 water samples were collected from 20 sampling sites based on the maximum water use declared by local communities. Temperature, pH, EC, TDS and DO were measured onsite and TSS, TH, Cl-, K+ and Ca++ were measured in the laboratory. Based on the EC values 100% water samples were within the desirable limit (1500 μS/cm). TDS classification showed that 100% sampling station’s water were fulfilled the criteria for irrigation purpose in shoreline area and 100% sampling station’s water were within desirable category in inland area. The study revealed that the trend of EC, TDS and Cl- concentrations were decreased from shoreline to inland villages, respectively. The study resulted the positive correlation between EC: TDS (r=0.712), TDS: Ca (r=0.585), DO: K (r=0.5041), Cl- : K (r=0.581), K: Ca (r=0.635) showed homogeneous sources of variables and same anthropogenic activities might be responsible for the excess concentrations in the study area. So, the water should not be used for drinking purpose without any proper treatment.

Hydrochemical study of groundwater in the aquifer system of the southeast coastal area of Bangladesh was carried out to investigate the processes of groundwater hydrochemistry as well as the suitability of groundwater for drinking purposes. Water samples from tube wells (depths 6.5–165 m) were collected and examined several water quality parameters to describe the hydrogeochemical characteristic. Most of the water samples were found as fresh and soft water with few numbers of hard and brackish water. The overall sequence of cation and anion throughout the study area are Ca2+> Na+> Mg2+> K+ and HCO3−> CO3−> NO3−> SO42−> Cl− respectively. Maximum water quality parameters satisfy the drinking water quality standard proposed by WHO. Piper diagram suggests that Ca2+- Mg2+- HCO3− (80%) and Ca2+- Na+- HCO3− (20%) facies are the predominant water type. Gibb’s plot implies a rock dominant inheritance that regulates the groundwater chemistry. The most significant hydrochemical processes in the study area are carbonate weathering and cation exchange. Correlation analysis recommends that TDS, EC, Na+, Ca2+, Cl− and SO42− are strongly correlated with each other, indicating their contribution to water mineralization. The principal component analysis (PCA) and Cluster analysis shows weathering and leaching of parent rocks are the leading environmental sources, while intensive farming incorporating the extensive use of pesticides and fertilizers might be another anthropogenic component that influences the groundwater hydrochemistry.

The contamination of water with heavy metals like arsenic, cadmium, nickel, zinc, lead, and cobalt presents a pressing and formidable challenge for numerous countries. The surge in industrial activities has exacerbated the pollution of freshwater sources, resulting in an alarming escalation of toxic metal concentrations in lakes, rivers, and underground water reservoirs. Consequently, millions of individuals in developing nations face significant health risks associated with heavy metal exposure. Compounding this issue is the limited accessibility to advanced water treatment methods, intensifying the gravity of the situation. Extensive research efforts have been dedicated to investigating low‐cost adsorbents derived from waste materials. It has been observed that the complete removal of heavy metals can be obtained using waste materials like eggshells, neem leaves, red mud, and black tea waste. The objective is to enhance the efficacy of heavy metal removal from water by employing modified waste materials as effective adsorbents. In this comprehensive review, concise and in‐depth information about the utilization of readily available waste materials is provided, including black tea waste, fruit peels, vegetable peels, sawdust, and other similar resources. This review emphasizes the kinetics and mechanisms involved in removing heavy metals. Additionally, the factors that impact the efficiency and extent of heavy metal removal in different waste materials have also been discussed.
