✦ Synopsis
An applied groundwater study of the 'Plana de Castell6n' was performed to investigate possible impacts of pollutants on ecological characteristics of the aquifer . The area is illustrative for a western mediterranean coastal plain, densely populated, industrialized, and with intensive agricultural land-use . During one year, six wells in a subsection of the plain were monitored, simultaneously sampled for zoological and physicochemical analysis . Heavy metals and pesticides were not (or at very low levels) detected in the wells . Low correlations were found between physicochemical and biological data, but there were indications that organic pollution affects the abundance of the fauna . A logarithmic relationship between abundance and CODBOD5-ratio is postulated . Salinization, an important threat to the groundwater of the area, was clearly reflected in the chemistry of one of the wells . Probably, this process has important consequences for abundance and diversity of the fauna .
