The residents of Katherine located in NT have been experiencing contamination of perfluorooctanesulphonic acid (PFOS) and perfluorooctanoic acid (PFOA). Therefore, the residents of Katherine and local base RAAFB at Tindall is drawing drinking water from the local aquifer. However, for doing so, they need the considerable cost to be implemented to take water treatment measures.
There are no PFAS detectable at the levels of Australian Drinking Guidelines. Based on this factors the study elucidates an alternative source of water supply with the help of Local Council elected member so that the source could continue providing them water for almost two years till the completion of the treatment plant.
Providing a new and safe source of water supply to Katherine is the new agenda of the local council elected member to ensure that they receive a long-term solution to prevent the contamination (Beh et al. 2014). However, the pilot treatment plan offered by Defence is not working in the present that is used to remove PFAS from Katherine's groundwater supply. In order to mitigate this issues, an alternative power supply has been planned for providing long-term supply. This alternative source of water supply is associated with the project that is investigating on renewed groundwater sources.
According to Cook et al. (2014), a program of drilling investigation will be established with an aim of surveying the sites for water supply within a short period of time. The elected council members have introduced a compulsory water conservation measures to take the pressure out from the groundwater supply. Therefore, it can be said that odd numbered properties can provide water only three days a week, on Mondays, Wednesdays and Saturdays from a time duration of 6 pm to 8 am. On the contrary, even number properties can provide the water supply on three days in a week such that on Tuesdays, Thursdays and Sundays from 6 pm to 8 am.
As stated by Gurung et al. (2015), conservation of water supply during this hours and days of the week can help them ensure safe health in protecting the local community from the contamination. It has been seen that Katherine is one of the highest user of water supply in the country with around twice the national average. Source report has found that one of the largest areas of waste is done through leakages of almost 500, 00 litres of waters per year on an average basis.
Working together with the government and helping developers the Katherine residents can evaluate and implement sustainable water systems in cities for a period of two years until the test. These alternative systems also include recycling of stormwater and waste waters through aquifers, stormwater harvesting and conservation of water for environmental resilience.
Therefore, from the study, it can be said that the resident of Katherine needs to immediately report to the elected member of the council to plan and utilise water trial in order to adopt alternative source sustainable water supply. The conservation and management of aquifer for the purpose of drinking water can be helpful for recycling the underground water introducing clean water for a huge number of users in the area. Therefore, through the partners, they can set new knowledge, safety designs in the governance framework.
