• Demands and competing uses of water
  Where water extraction is monitored because it is provided as a reticulated supply, then there is some knowledge and observation of the aquifer. In both Port Vila and Luganville aquifers are under increasing pressure from housing, agriculture and other developments. Outside of the demands of the reticulated supply, no formal assessment has been made of demand or impacts of competing use.
  
  

• Groundwater quality and quantity
  Information on ground water in Vanuatu is sporadic and mostly focused on Port Vila and Luganville. Groundwater quality in both urban centres of Port Vila and Luganville is generally good with only calcium hardness to note. Neither water supply currently requires treatment other than chlorination. However, in both cases aquifer levels are thought to be decreasing while pumping demands are increasing.

• Pollution
  Scabies, skin diseases and malaria are water related diseases and are the three most common health issues in Vanuatu. Poor drainage and waste management provide pools of water that are favourable breeding sites for malaria mosquito. Unmanaged and uncontrolled sanitation and wastewater are also major concerns.
