What\'s in your rainwater tank? Lead contamination concerns in Tasmania
Kingston sheet metal has created worrying tanks between 2010 and January 2013.
The lead problem was only found in the stainless steel tank and not in the galvanized tank.
\"We have a list of about 120 tank purchases, but this list is not enough to identify all the people on the list or contact them,\" Dr. Mark Veitch said . \" The senior medical advisor at the Health and Human Services Department told Ryk Goddard at breakfast 936.
\"People pay special attention to pregnant women and young children, and long-term high lead intake can cause damage to the development of the brain and nervous system,\" Dr. Veitch said . \".
Anyone who bought a stainless steel water tank from Kingston sheet metal, even if the tank is not used for drinking water, needs to call the Public Health Department 671 738 on 1800 so they can cross it off the list.
When some people were found to have elevated lead levels in their blood, the problem was exposed, prompting the public health department to alert and start investigating the cause.
\"We have 10 people coming back with high bloodshot ranging from 10 to 26 micrograms, and we ask our lab to inform us at 10 micrograms or more as an indicator of excessive lead exposure, dr. Roscoe Taylor, Director of Public Health, told Louis Sanders on Lane 936.
It was quickly determined that people with elevated lead levels had been drinking water in stainless steel tanks of the same manufacturer.
\"No cut --
Black and White, safety/unsafe levels [of lead].
We don\'t like lead in the human body. . .
\"The less the better,\" said Dr. Taylor.
The problem with the tanks is the solder used to connect them.
The lead content of the weld is high and is not properly sealed from the water, resulting in lead entering the water.
Lead only poses health problems for those who have been using water tanks as their primary drinking water supply.
It\'s fine to have a drink or two occasionally.
If they use these tanks as raised garden beds, it is unlikely that someone will have health problems, Dr. Veitch said, although all the dirt should be washed off from any vegetables grown in these tanks
The Galvanized Steel iron tank of Kingston sheet metal did not find a problem, nor was it a problem.
Roy Ormerod, state manager of workplace standard Tasmania, told Ryk Goddard that tank manufacturers know the rules for potential lead to ooze out into the water.
\"If a joint is using solder, once the tank is made, they have to make sure that only solder is used.
\"1 mg lead per liter, if the solder is completely dissolved, it will only be found in water,\" Mr Ormerod said . \".
Lead is a fortifier in welding.
\"We need to find out who installed these tanks and if any of them were installed by plumbers, we need to talk to them,\" Mr Ormerod said . \".
Mr. Ormerod said that all plumbers are aware of the Australian plumbing specification, which outlines the standards for water tanks and accessories that connect the home, water tanks installed by plumbers are safer than those installed by people who do not know the standard code.
If you are concerned about your rain tank or you think you may have a rain tank made of Kingston sheet metal, please call health department 671 738 on 1800.
