I previously posted about the problems with the drinking water in Flint, Michigan on 10/08/2015.
From that blog post:
“The city of Flint, Michigan changed its source of drinking water about 1 ½ years ago, leading to E Coli contaminated water being delivered through pipes containing lead (Pb).
‘…Flint, unable to come to an agreement on a short-term contract with Detroit, quit buying water from its system and signed on with a new system that will draw water from Lake Huron.’
‘Doctors are finding elevated levels of lead in the children in Flint, Mich., and local tap water is the likely cause. That's the latest alarming news to come out of the city, which switched its water source about a year and a half ago.’
‘It appears that the toxic metal [lead] had been entering drinking water through corroded pipes and plumbing materials, according to Flintwaterinfo.com.’
A few days ago, on Tuesday, 12/15/2015, a State of Emergency was declared in Flint, Michigan because of the high lead levels found in the blood of resident children:
This article states that, “[a]ccording to the World Health Organization, ‘lead affects children’s brain development resulting in reduced intelligence quotient (IQ), behavioral changes such as shortening of attention span and increased antisocial behavior, and reduced educational attainment. Lead exposure also causes anemia, hypertension, renal impairment, immunotoxicity and toxicity to the reproductive organs. The neurological and behavioral effects of lead are believed to be irreversible.’ ”
This story was presented 12/15/2015 in several national news broadcasts:
“While lead poisoning cannot be reversed, experts say that the right kind of nutrition, parenting and community services can mitigate the worst damage: learning disabilities, speech deficits and severe behavior problems in the coming years.”
Residents are concerned about the permanent damage on their children, the future effects of the lead contaminated drinking water, and the efficacy of the filters provided by the city.
I post about this topic only because it’s a timely issue that was discussed earlier.
On a lighter note, if you are looking for Holiday Class Activities, check out my blog post dated 11/20/2015.
Next week, many of you will be travelling and/or celebrating Christmas that Thursday/Friday. I won’t post that week, but my next blog post will be around Tuesday, 12/29/2015.
