World Toilet Day is significant as we face a global sanitation crisis.

SDG 6.2 on safe access to sanitation services is off track with over 3.6 billion people lacking safely managed sanitation services. This World Toilet Day highlights the importance of sanitation for the protection of groundwater sources that have been reliable sources of fresh water for the planet.

Lack of sanitation facilities and services may lead to pollution of groundwater sources through the infiltration of faecal matter into the aquifers.
