Rather than regulating each type of microorganisms to a specific concentration, regulators have established a zero tolerance goal for microbiological contaminants and have used indicator organisms, particularly fecal coliforms, to show the possible presence of microbial contamination from human.

Riparian areas are invariably defined as being directly adjacent to a waterbody, typically a stream. Definitions vary to the extent that they include all stream types, from perennial to ephemeral (see Box ).

Some are restricted to fresh waters, while others incorporate marine and estuarine waters as well. assessment perspective because freshwater is a limited natural resource.

Degradative water use, in contrast, denotes the use of water with associated quality alterations and describes the pollution of water (e.g. if tap water is transformed to wastewater during use). European waters and on the ecosystem services provided by aquatic ecosystems.

This work proposes a methodological framework for the biophysical assessment and the economic valuation of water ecosystem services at the water body, the catchment and the European scale.
