Impact of Nitrate Vulnerable Zones and Catchment Sensitive Farming on Water Quality in UK: Case Study of Ingbirchworth and Scout Dyke Reservoirs

The rivers and water streams are considered as a source of fresh drinking for the human being on earth. main entering to these reservoirs is surface run off, snow melting underground water. at river’s mouth generally in form small which clean but they flow down catchment, pollutants nutrients start enter larger amounts due anthropogenic activities advanced land use by beings. As per inspection chief inspector “Drinking Water Inspectorate (DWI)” 2016, out more than 4600 bodies 3700 England, only one sixth could get “good” status two third “moderate” European union standards. This though good achievement Europe alarming also, all required have achieved specified standards 2021 (extended 2027 some categories). phenomenon pronouncing complications or compensatory from where taken utility companies treated domestic supply incurring an enormous cost its treatment before consumption. can be if strict control implemented entry pollutants/ off using thorough catchment scale sensitive strategies. UK has been implementing measures under Environment Agency (EA), Department Environment, Food Rural Affairs (DEFRA) other organizations like “Natural England”, “River Trust” utility/ achieve desired quality managing whole framework directive (EU WFD) 2000.The farming nitrate vulnerable zones policies were started 1992 full practice different stewardship schemes fertilizers farmlands arable lands.

A partial success controlling values nitrates, phosphates, suspended solids slurry/ implementation techniques. However, temporal special variations show variable result presence phosphates times, limits 11.3mg/L, 0.1mg/L 25mg/L respectively. requires holistic efforts bad practices adjacent farm/arable lands improvements areas.
