The primary issues with groundwater quality in the country are high concentrations of fluoride, arsenic, manganese, iron, hardness, and salinity in some localities. Poor selection and application of geophysical methods, shallow drilling depths above productive fractured zones, complete reliance on thin shallow aquifers, poor construction of drilled boreholes, lack of maintenance of mechanized boreholes, and limited aquifer recharge in some parts of the country are some of the potential causes of frequent borehole drilling failure, low borehole yields, and drying up of hand-dug wells and some boreholes during the dry seasons. For effective and efficient groundwater development, it is recommended that groundwater exploration be conducted to a minimum depth of 200 m using the combined application of the electromagnetic method, or two-dimensional magnetotelluric, two-dimensional electrical resistivity, and two-dimensional induced polarization methods in the order presented.

Analysed twelve common water quality indicators, including pH, temperature (temp.), dissolve oxygen (DO), secchi depth (SD), salinity (Sal), biological oxygen demand (BOD), electrical conductivity (EC), total dissolve solid (TDS), hardness (Hard), Alkalinity (Alk), total nitrogen (TN), total phosphorous (TP) and plankton density (PD) to assess the water quality index (WQI).

The WQI value ranged from 87.68–125.88, indicating very poor to unfit for consumption water quality. Strong correlation among PD, BOD, and DO, was observed by multivariate analysis.

This review examines recent advancements in the application of nanofiltration (NF) membranes for the removal of pharmaceuticals from wastewater. It analyzes removal mechanisms primarily size exclusion and electrostatic repulsion along with the influence of membrane material, pore size, surface charge, and water chemistry. Various NF membrane types, including commercial, polymeric, ceramic, and hybrid designs, are categorized and compared. Economic aspects, such as capital and operational costs, are also assessed. The NF membranes show high efficacy in removing a broad spectrum of pharmaceuticals, particularly high-molecular-weight and charged compounds. However, removal performance varies with membrane and contaminant properties. The review highlights cost challenges and stresses the need for life-cycle economic evaluations. Key research gaps are identified, including the need for enhanced selectivity, fouling resistance, and long-term sustainability.

The reactors were operated for 12 months under simulation of real precipitation, with monthly leachate collections. Samples were analyzed for cell viability using the MTT assay on human keratinocytes and for metal concentrations (Al, Ba, Co, Fe, Mn, and Zn) using ICP-OES.

Median values show higher barium in the dry season and manganese influenced by a peak, though more widespread in the rainy season. Among the treatments evaluated, reactors containing thermally dried sludge presented the most pronounced cytotoxic effects. It was also found that the dedicated landfill showed the worst cytotoxicity conditions, with cell viability of less than 50 per cent. The study demonstrates that sludge drying methods, disposal type, and climatic seasonality directly influence leachate toxicity, emphasizing the importance of cytotoxic analysis as a complementary tool in environmental waste management.

It is the lifeline for millions of people and directly influences their lifestyle and livelihood.

To alleviate it, many scientists have investigated and attempted to predict water pollution levels using various approaches. Most of these studies are focused on univariate prediction and perform poorly when it comes to predicting multiple river water pollutants. The present investigation focused on the Ganga water pollution profiling based on physiological parameters (DO, BOD, TDS, Conductivity & Metal analysis) on a monthly dataset for three years. Furthermore, it proposes a Wavelet-LSTM model that may achieve a balance between local univariate prediction accuracy and overall accuracy to observe the trend of river water pollution more widely. The model integrates signal processing and deep learning techniques by utilizing wavelet decomposition at a specific scale to obtain the low and high-frequency features of the target data, constructing a feature matrix, and feeding it into an LSTM network for prediction. The model was used to make predictions on the DO and BOD dataset of Ganga pollution in Uttar Pradesh, India. The observed results indicate that the proposed model obtained robust performance for multiple water pollutant factors. The R<sup>2</sup> value ranges between 94 % and 99 % for the complete prediction of all pollutants.
