Here is a link that an increase in being exposed to lead  especially to children will lead to more criminal activity. And that a decrease shows a decline in criminal activity.  ..." reductions in
childhood lead exposure in the 1970s and 1980s accounted for more than half of the violent
crime decline of the 1990s."

Interesting also is the correlation between lead in water pipes and the distance by railroad to the nearest lead refinery. (Either Detroit or Chicago in Ludington's case)

Also it seems Traverse City has been replacing lead goosenecks for some time and has fewer than 100 left to replace. They also offer free water testing to people for places that still have lead goosenecks.

It looks like the Traverse City Council has a more pro-active concern for lead contamination rather than Ludington's maintaining the status quo of giving the deck chairs a good arranging. 

And for good measure here is a link about the development of tetraethyl lead is gasoline.

A quote from a Dr. Hamilton seems to describe the vision of out current city council,  "dizziness in the head, with continuous great pain in the brows, blindness, stupidity".

Interesting post and links shinblind. Even if all the lead piping and copper pipe with soldered joints containing lead were removed the problem of lead poisening will not go away. A much bigger problem in all urban areas is lead in the soil which is contaminated from lead in car exhaust over many years and lead from the paint peeled off houses before new paint is applied. I attended  a seminar some years back regarding this problem. The speaker told the attendees that they will look at their homes and yards in a totally different way when they go home that night. He was right. We are surrounded with lead contaminated soil.

Thanks for the supplemental links showing that lead can come from alternate sources.  Unfortunately, our city leaders automatically shift these alternative sources of exposure to lead as the culprit for Ludington, to get their own necks out of any calls for liability due to the water system's prevalence of lead goosenecks. 

I don't understand how they can explain a graphic like the one below showing lead tests for a recent ten year period, barring them showing that our public parks and playgrounds are infused with leaded gas, paint, etc. from some previous age.  You will notice that all of the blood lead elevated children tested have one thing in common: Ludington is their water supply system and their municipal pipes still contain lead.

A very telling story is represented on that map. Disturbing as well.

Does anyone know if the soil was ever tested for lead at the homes where the children with elevated blood levels reside?

The facts from previous research shows that the percentage of older homes in both Manistee and Oceana counties are similar to Ludington, yet Ludington remains the one's with an issue.  Remarks  by the city that the source is caused by the ingestion of paint chips don't seem to be backed up by any facts nor any common sense.

Low levels of lead in the soil may be contained by the simple addition of lime. In worse cases super phosphates can also be added to the soil to control lead although its use is restricted in Michigan do to environmental concerns. Nothing like rule of unintended consequences.

Interesting subject matter, and very disturbing. The videos tell us quite a bit of information. But the graphic that X posted is rather shocking to say the least. I would think that EPA doing heavy soil testing around Lud. is much needed, anywhere and everywhere that residents ask or suspicion their land.
