Direct injection of water into the groundwater zone is one method of recharging and can be used to create a barrier against saltwater intrusion in coastal areas. Surface spreading or dune or bank filtration are more often used; as 36 the water percolates downwards, the soil or sand acts as a natural filter to remove particulate matter, microorganisms and some dissolved compounds. Depending on the soil characteristics and the extent and type of contamination of the water used for recharging, the groundwater may become polluted.

These are broad-spectrum herbicides that have been used extensively in both agricultural and non-agricultural situations. Because they frequently appear in groundwater, several countries have banned or restricted the use of products containing these active ingredients, and a recent assessment (49) revealed a statistically significant downward trend in the contamination of groundwater with atrazine and its metabolites in a number of countries, including Austria and Switzerland and parts of France, Germany and Latvia.
