  • Michigan admits mistakes in Flint water testing

    Michigan officials admitted Monday that the state made a mistake during its testing of the quality of drinking water in the economically battered city of Flint, where blood lead levels in some children had more than doubled since the city switched its water supply to a cheaper source.

    Activists in Flint had earlier accused the state’s environmental officials of ignoring their concerns about their city’s drinking water.

    The state’s Department of Environmental Quality said it had followed the wrong federal protocol on corrosion control for the treatment of Flint River water, after the city last year switched its water source to the river instead of Lake Huron in a bid to save money.

    “The water testing steps followed would have been correct for a city of less than 50,000 people, but not for a city of nearly 100,000,” the department’s director, Dan Wyant, said in a statement. Flint’s population is about 99,000.

    So, what's the kid's level of lead in their blood got to do with the water and testing?

    Sounds like the two are not related to me.

      The wrong/faulty testing for contaminants like lead in water, and rising lead content in children's blood, are not connected?

      Maybe it's due to that all lead-paint diet.

        Not necessarily. It could be due to the piping between the treatment plant and the home, the piping in the home (in older homes with leaded steel galvanized pipes you should let the water run for about 15 seconds before using as sitting water will accumulate lead and other contaminants from the pipes).

        Let's say you live a mile from the water treatment plant. Your water travels through a mile + of piping to reach your home. That water doesn't get tested at your faucet. It will contain higher levels of organics, turbidity, and possibly metals, hard water, and any number of other things by the time it reaches your home.

        If this switch occurred about a year ago then the cause of the rise in children's lead in blood isn't due to water unless it exceeds federal standards by like a hundred times or more. Of course, since the levels themselves aren't listed in the article they could be miniscule and have risen some but nowhere near what would be harmful since the current EPA standard for lead in drinking water is essentially zero.

        I'd say the article is being alarmist and inaccurate as it doesn't state what the actual levels are / were. But, that seems to be normal with the media when it comes to something were science and technology applies.

          The source is questionable.

          However, From local sources;

          A lot of the plumbing especially in the older homes are lead soldered copper. In some extremely old ones, it can even be lead.

          The dirty Flint River water, which requires a lot more treatment then water from Lake Huron, became much more corrosive from the treatment. Results, lead started leaching out of the older plumbing into the water. Results, after a year of use, lead levels in the bloodstream became elevated in kids living in homes with lead in their plumbing.

          Last week, the decision was made to switch back to the expensive Detroit source from lake Huron. That will be used until the new Lake Huron regional pipeline is completed.

            This bit is odd...

              [B]lood lead levels in some children had more than doubled since the city switched its water supply to a cheaper source.

              The percentage of children "with above-average lead levels had nearly doubled"...
              Hanna-Attisha said she looked at 1,746 test results from Flint children this year, compared to earlier results when Flint used Lake Huron as its water source. The percentage of kids with above-average lead levels had nearly doubled, according to the study. In certain areas, it tripled.

              The report did not say that "lead levels in some children had more than doubled."

              Is the Al Gorezeera reporter lying or just stupid?

                The article makes no sense at all, since Federal standards for lead are not dependent on the population size.

                  If I had to bet money, I would say it was incompetence. A misreading of the report on "doubling" leads to lead levels having "doubled" - rather than just incidents of higher lead having doubled/trebled in some areas.

                      As I said, very questionable source.

                      Fact, the number of cases of elevated lead levels have doubled.
                      Fact, lead is leaching out of the plumbing, usually older copper soldered using lead based products.
                      Fact, the increased treatment needed for the river water has caused the problem.
                      Fact, the lead issue is not occurring at the treatment plant, but at the destination such as the home, business, and schools.

                      Not known is if any of the kids with elevated lead levels have been eating lead pigmented paint in the older homes, a product that has a sweet taste, or eating and drinking from cheap imported Chinese china, or chewing on toys made in China containing illegally used cheaper lead pigmented paint.
