If you search “lead in public school drinking water” you may see news
every day on either lead contamination or actions taken in a particular
state to measure lead levels in school drinking water. In the wake of
the Flint drinking water crisis due to...
If you read my blog post last year on lead contamination in a community
garden in Vancouver, Canada, you would know how soil contaminated with
heavy metals can be so detrimental to our health. Just two months ago,
while the Indiana governor, Mike Pen...
If you read my previous blog post on heavy metal contamination event in
Colorado’s Animas River, you have heard how a single mistake can lead to
the contamination of a natural resource as along with economic
consequences and public health concerns. J...
While the story is still developing for lead contamination in drinking
water at Flint, Michigan (to see how it can happen, download the lead
