	The groundwaters of the Permo-Triassic aquifer of Manchester display a wide range of chemical characteristics with concentrations for most elements varying over several orders of magnitude. These characteristics are determined largely by natural reactions between the groundwater and the rocks through which it passes. This baseline has been modified by diffuse pollutants including agricultural fertilisers leading locally to high nitrate (NO<sub>3</sub>.N) and increases in other major elements such as potassium (K), sodium (Na) and sulphate (SO<sub>4</sub>). Most chemical parameters are highly variable due to the complex geology and the presence of drift deposits, which differ in thickness and type. These drift deposits have a significant effect on recharge of the aquifer but provide a degree of protection from diffuse or point source pollution.
