Water risk refers to the possibility of problems to do with water. Examples are water scarcity, water stress, flooding, infrastructure decay and drought. [18]: 4 There exists an inverse relationship between water risk and water security. This means as water risk increases, water security decreases. Water risk is complex and multilayered.

Environmental disasters have historically affected agriculture, wildlife biodiversity, the economy, and human health.The most common causes include pollution that seeps into groundwater or a body of water, emissions into the atmosphere, and depletion of natural resources, industrial activity, and agricultural practices.
In many areas of the world, groundwater pollution poses a hazard to the wellbeing of people and ecosystems. One-quarter of the world's population depends on groundwater for drinking, yet concentrated recharging is known to carry short-lived contaminants into carbonate aquifers and jeopardize the purity of those waters.
