Victor Harbor residents are complaining of multiple health problems as a result of chloramine being added to their water supply from Myponga Reservoir.
And while they’re suffering headaches, itchy skin and sleeping problems, they say it’s even worse for pet fish going belly up in their tanks and ponds.
Yankalilla, Normanville and Carrickalinga residents told of similar problems last year, including rashes and diarrhoea, from drinking and bathing in mains water when SA Water starting disinfecting supply to 3000 households with chloramine.
Famed international environmental crusader Erin Brockovich then threw her support behind residents, describing use of chloramine – created by adding ammonia to chlorine – as “a critical mistake”.
In December, use of chloramine was extended to another 25,000 homes in Victor Harbor, Encounter Bay, McCracken, Chiton, Port Elliot, Middleton, Goolwa, Hindmarsh Island, Sellicks Beach and parts of Aldinga Beach.
John Stankovich of Encounter Bay said problems started almost immediately.
“Within a week my back started itching and I was so desperate I went out and bought a back scratcher,” he said. “Then it worked its way up to my shoulders, my neck and under my chin. It was just so annoying.”
Mr Stankovich said several neighbours had water filters installed at considerable expense to avoid health effects and he felt SA Water should subsidise the cost.
He said his symptoms settled when he switched to drinking bottled.
Other locals posting on a Victor Harbor community Facebook page say they are still suffering a range of health effects and their fish have died.
Fish and other aquatic pets are sensitive to both chlorine and chloramine, so tap water has to have additives before being used to fill tanks, ponds and aquariums.
David de Brequet of Victor Harbor said he believed the concentration of chloramine was too high because all of his fish were dying even after he increased the amount of “the most advanced water conditioner available” to five times the recommended dose.
“I saved them by doing a full water change with rain tank water, but I was lucky to have this available,” he said. “Meanwhile, we are drinking water that kills fish.”
SA Water confirmed it has “provided one-off service gestures to a small number of local customers on a case-by-case basis, to support them with any impacts to their fish”.
Independent candidate for Finniss Lou Nicholson asked whether chloramine was now preferred because public access to the reservoir had stirred up sediment and organic matter.
SA Water senior manager of water expertise and research Dr Daniel Hoefel confirmed the switch to chloramine was to “safely manage” chemicals called trihalomethanes, which build up when chlorine reacts with leaves, soil and sediment. Both he Environment Minister David Speirs said the move was not related to public reservoir access.
Trihalomethanes have been linked to cancer and reproductive health issues.
Dr Hoefel said chloramine was commonly used interstate and overseas and had been used in parts of regional SA for decades including Port Pirie, Port Augusta, Whyalla, Keith, Yorke Peninsula, southern Adelaide Hills, Tailem Bend, Strathalbyn and Keith.
