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.
