“…99 Effective communication is therefore valuable to reduce uncertainty and build public support and this can be achieved by improving awareness through constructive and continual engagement with water reuse stakeholders. 58,[100][101][102] One way of achieving this may be to involve members of an effected community more closely in the risk management process. 103 When communicating risk, it is important to understand that risks might affect stakeholders throughout the system (e.g.…”

“…Total coliform (TC). TC is a nonspecific indicator of gross contamination, based on a mix of E. coli and other intestinal bacteria such as Enterobacter aerogenes, although the latter also grows on plant matter in the environment (Derry et al, 2006;Mara and Horan, 2003). The small increase in TC noted in the final effluent coincided with a lid having been removed from the sampling port on two occasions when vegetation gained entry to the drainage chamber.…”

“…Since 1960, recycled water has been used for irrigation in the Hawkesbury Water Reuse Scheme (HWRS) [26]. Due to this long history of irrigation with recycled water, the HWRS has always been on the radar of the Western Sydney scientific community, prompting the completion of several risk assessment studies related to recycled water irrigation [28][29][30][31][32][33][34]. However, the effect of various irrigation water types on the mechanism of salt formation in the soil requires additional research.…”

Impact of Recycled Water Irrigation on Soil Salinity and Its Remediation

Continuous use of recycled water (treated wastewater) over a long period of time may lead to the accumulation of salt in the root zone of the soil. This is due to the relatively higher levels of salt contained in the recycled water compared to a town water supply. The increase in salt concentration in the soil can adversely influence the amount of water a plant can uptake from the soil due to the osmotic effect. Despite significant benefits, recycled water may deteriorate soil health in terms of increased salinity and sodicity. Although several studies in the past have highlighted the increase of soil salinity due to recycled water irrigation, the phenomenon depends on the variability of soil characteristics. In this study, the impact of using three different types of irrigation water (with electrical conductivity 0.2, 0.8, and 2.0 dS/m) on the mechanism of salt accumulation in the soil was investigated. To contribute to the addition of the existing knowledge of soil salinisation, soil from two paddocks (i.e., D33 and Yarramundi) in Western Sydney, Australia were analysed, and relationships among parameters associated with salt accumulation were evaluated using the results from continuous column studies. Results show that if the irrigation is conducted with high saline water, there is a possibility for salinisation of soil to occur. To prevent this from occurring, one of the solutions could be to use a normal town water supply for irrigation at some intervals. This will allow for the leaching of excess salt accumulated in the soil to deeper layers.
