Lead Poisoning - Flint Edition
An earlier news story included a picture of water pipe ends with substantial build-up of deposits inside the pipe. This could probably have been prevented by a proper chemical treatment program. But, it appears that the funds to be used for water purification were either diverted to other, politically important uses, or missing because reduced tax revenues due to the departure of high paying manufacturing.
One of the main complaints of citizens detailed on TV news was the result of lead contamination. As implied in that story, the lead contamination was most likely the result of leaching of lead from the water line joint seals by the new polluting being used. By explanation, cast iron lines which were installed many years ago, often before WW II, were connected by ‘bell and spigot’ slip joints that were sealed with lead poured into the joint. After the war, the pipe used was called ‘ductile iron’ or were steel and the joint seals were a rubber gasket which was much more seal effective and allowed for some expansion in the pipe with temperature changes whereas such expansion movement could crack the lead seals and thus allowing leaks.
Another source of lead contamination reported was using lead pipe for the ‘service lines’ connecting the buildings to the main distribution lines. That is a first in my experience. Lead pipe was previously used for sewer lines in the buildings, but not for water lines. In recent decades, even sewer lines have been replaced with the PVC.
Still later plastic, such as PVC or PE pipe, with the same bell and spigot connections with rubber seals came into common usage. These tend to expand and contract less and offer more flexibility to move with ground shifts. They also have the ability to tolerate freezing because of that same feature. Also, with the plastic there is no tendency to find rust in the water from the pipe as with iron or steel.
Actually the situation in Flint is a more pronounced example of what is, or could be, going on in many cities where normally accepted maintenance procedures are being neglected or postponed. Even in Tulsa, Oklahoma, a city much younger than Flint, Michigan, there have been a large number of line breaks reported which were blamed on soil shifting due to temperature changes.
All this is a glaring example of the usual tendency of officials of government at all levels, from schools to the White House, to neglect the ongoing maintenance necessary to keep facilities usable for the original purpose. Then when those facilities become overly expensive to restore, they resort to bond issue financing, at great added expense, to restore or replace the facility. Their attitude seems to be ‘let the populace (tax payers) pay not only the cost of repairs but the added expense of the interest and fees embedded in secured bonds.
Then there is that addition cost to the taxpayers created by exorbitant salaries and expense accounts of elected officials and hired administrators. Decisions by past and present officials and administrators affect both present and future costs as well as life risks to human lives in their communities.
