THIS ARTICLE IS A CASE STUDY OF HISTORICAL PROJECTS HYDROSOLUTIONS HAVE WORKED ON.
CHLOR-ALKALI MANUFACTURER, Kwinana, Swan Coastal Plain, Western Australia
Groundwater investigation
An investigation of groundwater quality was undertaken at a chlor-alkali manufacturing plant, which produces chlorine gas, sodium hydroxide and hydrogen from brine by electrolysis. The manufacturing process involves solid salt dissolved in heated water to form a hot brine. Leakage of brine through the dissolver had lead to a a salt plume within the fresh underlying groundwater within the Safety Bay Sand superficial aquifer.
A geophysical survey using the Em34 was undertaken to produce electomagnetic resistivity profiles of the operational site. These data were used to infer potential points of leakage to groundwater.
A groundwater monitoring network was established to determine the hydrogeological conditions
and groundwater quality in 3-dimensions.
The rate of movement and salt flux was estimated.
It was concluded that the low migration rates would promote natural attenuation of the salt
by advective dispersion in the absence of any downgradient users.
Recommendations were made for an ongoing monitoring program.
