A resident in the South Blount Utility District said they got a notice of violation of safe drinking water standards indicating their drinking water was contaminated with high levels of lead.

According to the resident, the notice says the "action level" (upper limit) for lead in the water is .015 mg/l, and the June 2008 measurement was .075 mg/l, which is five times the allowable amount.

The notice reportedly said residents should run their water longer or consider using bottled drinking water.

Maybe an expert can explain how running your water longer will help if the lead is already in the water from the source? Also, it's too bad people are being advised to run their water longer in the middle of a drought. And not everyone can afford bottled drinking water.

Has anyone else received a similar notice? (We're on Alcoa city water, and it usually gets A+ reports and I don't recall ever receiving such a notice.)

At any rate, does anyone know if Mayor Jerry Cunningham has advised the South Blount Utility commissioners to do something about the lead in South Blount Utility water if they want to keep their jobs?

The Tennessee Department of Environment and Conservation says "Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure."

UPDATE: This is not the first time. The utility had violations in February of this year [1]. District manager Henry Durant said at the time "We're out of compliance, and we're desperately trying to find a solution." There were also violations in 2006 [2].

SBUD says the problem is with older homes which have copper plumbing with lead solder on joints. This is why running the water longer is supposed to help. According to TDEC, utilities that test positive for lead in drinking water at the tap are supposed to treat the water with a "corrosion inhibitor," which is a "substance capable of reducing the corrosivity of water toward metal plumbing materials, especially lead and copper, by forming a protective film on the interior surface of those materials." Sounds tasty! Does anyone know if SBUD has done this?

So now the question is, why the big rush to add fluoride to the water? It would seem that lead in the water is a serious, well documented, well understood problem in terms of its effects on human health. Shouldn't removing lead take priority over adding fluoride? Has Mayor Cunningham remarked on the levels of lead in SBUD drinking water, or offered a plan to address the problem?

UPDATE: The Maryville Daily Times reports today [3] (Aug. 13) that SBUD says the problem is isolated to older homes with lead pipe or plumbing with lead solder and that they do not have any supply lines with lead pipes. According to the article, SBUD says they took steps in June to implement changes recommended by a Virginia expert regarding anti-corrosion treatment of the water. The article says the problem has been ongoing since 2006, but does not say if anti-corrosion treatment was added before June of this year as required by law. The article also quotes the Tennessee Department of Environment and Conservation as saying the utility is still out of compliance but improving. The article doesn't mention if Mayor Cunningham has been involved in monitoring the situation or working with SBUD on solving the problem.
