What Makes Kingaroy's Water Unique?
Local geology and source profile
Kingaroy's drinking water is supplied by South Burnett Regional Council, drawing from Boondooma Dam on the Stuart River and local sub-artesian groundwater supplementation for the South Burnett Regional Council LGA distribution in south-east Queensland. Water hardness in Kingaroy is measured at 259.5 mg/L — classified as hard, substantially exceeding the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Kingaroy — the regional centre of the South Burnett Region, known as the 'Peanut Capital of Australia' and celebrated for the South Burnett peanut and wine industry, the Kingaroy Heritage Museum, the South Burnett Regional Council civic and service hub, and the major inland regional community of the South Burnett plateau between the Darling Downs and the Wide Bay hinterland — receives very hard supply from the South Burnett Regional Council distribution, among the hardest regional Queensland water supplies.
Kingaroy's very hard supply reflects the high mineralisation of the Boondooma Dam catchment and sub-artesian groundwater supplementation in the South Burnett regional water supply. The Boondooma Dam catchment and South Burnett geological terrain includes Triassic and Jurassic carbonate-cemented Surat Basin formations and basalt of the South Burnett Tablelands — percolating through limestone and sub-artesian pressure systems that accumulate very high dissolved calcium, magnesium, and mineral salts. At 259.5 mg/L and TDS 754.4 mg/L, Kingaroy's supply is substantially above the ADWG 200 mg/L aesthetic guideline, reflecting one of the harder regional Queensland municipal supplies.
Kingaroy residents face significant daily limescale challenges — kettle descaling every one to two weeks is typical, shower screens and tapware accumulate heavy deposits, and hot water systems require annual inspection. The elevated lead reading (0.005 mg/L) warrants briefly running the cold tap before use. Under Queensland water restrictions, outdoor watering is regulated. South Burnett Regional Council provides water quality information online, with all ADWG health standards consistently met. Kingaroy's peanut capital community benefits from supply meeting all ADWG safe drinking standards.
Geology & Source: Supplied by South Burnett Regional Council from Boondooma Dam on the Stuart River and local sub-artesian groundwater supplementation — the Kingaroy South Burnett regional supply carries hard water at 259.5 mg/L with extreme TDS of 754.4 mg/L, substantially exceeding the ADWG aesthetic guideline of 200 mg/L, reflecting the high mineralisation of the South Burnett Jurassic–Triassic carbonate and geological formations and sub-artesian groundwater supplementation.
