Nitrate in Drinking Water

Synopsis
Looks at how nitrate gets into the soil, and its progress thrgh it. Uses Hatton catchment area as an examples and examines the opposing views of the Rothamsted Experimental Station and the Water Research Centre. The cost to the water industry is compared to the cost to farmers of restricting fertiliser use. An alternative to preventing nitrate entering the water is to remove it once it is there. It is Rothamsted Experimental Station’s opinion that reducing the application of fertiliser will have little impact on the quantities of nitrate leaching into ground water. Rothamsted workers speculate that significant amounts of nitrate might be entering the soil, not from the farmer, but from other sources, like emissions from the private motor car.

Notes
NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
