Risk

Pollution containing bacteria of intestinal origin.

As opposed to "chronic pollution", it is a pollution characterized by unpredictability about: the time of the accident, the place of the accident, the type of pollutant, the amount spilled, the circumstances of the accident, the consequences of the accident.

Dramatic result of erosion (destruction of farmlands, flooding of roads, etc). The main consequences of a mudslide are the degradation of the agricultural potential of the soil and of the quality of rivers caused by increase in turbidity, transfer of

Process by which a biotope - and (or) a population or an entire community - is exposed to a chemical or radioactive pollutant.

Area where overflows can spread in the floodplain and which plays a significant role in flood control. Mapping these flood-storage areas allows better land use management in the valleys.

Toxic substance, whose emissions and losses into the environment must be reduced, in accordance with the Water Framework Directive 2000/60/EC. As planned in the Directive, a first list of substances or families of priority substances was defined by Decision No 2455/2001/EC of the European Parliament and of the Council of 20 November 2001 and was included in Annex X. These priority substances were selected according to the risk they pose to aquatic ecosystems:

Substance which, at certain concentrations in water, presents a risk to public health, animal health or living beings and ecosystems in general. Certain substances and their effects are relatively well identified (heavy metals, some micro-pollutants). For others, the risk to public health and ecosystems is difficult to assess, thus deeming it prudent to use the

All internal measures of a supply unit (drinking water supply system) to supply users in critical or crisis situations (accidental pollution of the resource, etc): interconnections between systems, use of different water resources, etc. These emergency solutions to be implemented must be listed in the specialized emergency response plan developed by the departmental administration. By extension, it means being able to ensure

More or less likely danger or inconvenience (immediate or long-term) to which public health is exposed. The identification and analysis of risks related to a phenomenon (flooding, contamination, etc) usually allows predicting its impact on public…
