OGWDW Exercise:

Imagine you are a community leader responsible for ensuring the safety of your town's water supply.

Task: Research and identify three potential threats to your town's groundwater and drinking water. For each threat, explain:

  • The source of the threat: What is causing the contamination or potential harm?
  • The potential consequences: What could happen if the threat isn't addressed?
  • Possible solutions: What steps can your community take to mitigate or prevent this threat?

Example:

Threat: Agricultural runoff containing fertilizers and pesticides

Source: Overuse of chemical fertilizers and pesticides in local farms.

Consequences: Contamination of groundwater with harmful chemicals, posing risks to human health and the local ecosystem.

Solutions: Encourage sustainable farming practices, implement buffer zones between farmlands and water bodies, and promote the use of organic fertilizers and pest control methods.
