Multi-drug-resistant bacteria pose a significant threat to public health. The role of the environment in the overall rise in antibiotic-resistant infections and risk to humans is largely unknown. This study aimed to evaluate drivers of antibiotic-resistance levels across the River Thames catchment, model key biotic, spatial and chemical variables and produce predictive models for future risk assessment. Sediment samples from 13 sites across the River Thames basin were taken at four time points across 2011 and 2012.

The present study has been undertaken to evaluate the performance of wastewater treatment systems (WWTS) in three different districts (Kolkata, Howra and Hugli) in West Bengal, India. Performance of these wastewater treatment plants are essential parameter to be monitored as the treated effluent is discharged into River Ganga which is the National River of India. The performance evaluation will also help for the better understanding of design and operating difficulties in wastewater treatment plants.

Over the past years, due to rapid industrialization and advanced agricultural activities environmental deterioration is becoming a major concern. Water is one of the most important and basic natural resource which is being used in industries, agricultural activities as well as for the domestic and commercial purpose. These activities leads to discharge of wastewater, hence, accurate analysis of wastewater is crucial for maintaining the health and safety of the people. Water from all three sectors i.e.
