Ever since I began studying nutrition and holistic health sciences in the 1970s, I’ve been concerned about the irresponsible ways certain elements on the Periodic Table are used by science, technology, agriculture, food processing, and even medicine.
Recent revelations of toxic heavy metals, e.g., lead in Flint, Michigan’s municipal water supply —and others ; chemicals such as PFOAs and PFOSs in municipal and private wells polluted by the U.S. Naval Air Station in Willow Grove, Pennsylvania  and the chemical industry also contaminating numerous localities’  underground water aquifers; plus exorbitant amounts of aluminum in Mount Shasta, California rain water  must be taken seriously by everyone, but most of all, by those responsible for manufacturing and spreading toxic pollution; by the ‘paper tiger’ U.S. Environmental Protection Agency—whom does EPA protect—polluters?; and, particularly, the do-nothing, heavily-lobbied U.S. Congress.
Most of the toxic heavy metal contamination usually and inadvertently occurs as a result of some technological ‘gift’ to humankind, or as an ingenious cost-cutting idea to balance a budget line item.
Flint’s water crisis came about from changing water systems to save money ! The U.S. Naval Air Station at Willow Grove sprayed firefighting foam . Mount Shasta, California rain water contamination is the result from the federal government’s Solar Radiation Management project to deal with global warming aka “chemtrails” .
Incidentally, more underground wells and surface water contamination is yet to be found and/or scientifically identified from all the glyphosate and glufosinate spraying used in growing genetically engineered crops since the 1990s, or as pre-harvest crop “staging”  and desiccant processes several days before harvesting grains and legumes—yet another reason for eating an organically-grown, plant-based diet.
The bar chart below shows all deregulated crops, sized by the number of genetic varieties approved for each.
[Note that GMO Rapeseed also can be GMO canola!]
Another equally devastating contamination of water supplies is the hydraulic fracturing process to extract energy from shale sands commonly called “fracking” . According to Wikipedia, Fracturing
Fluid is typically a slurry of water, proppant, and chemical additives. Additionally, gels, foams, and compressed gases, including nitrogen, carbon dioxide and air can be injected. Typically, 90% of the fluid is water and 9.5% is sand with chemical additives accounting to about 0.5%. However, fracturing fluids have been developed using liquefied petroleum gas (LPG) and propane in which water is unnecessary. 
One of the ‘byproducts’ of fracking is water that burns! How can you drink, cook and bathe in “fire” water?
water! Most commonly used ice melting chemicals are sodium chloride, calcium chloride and magnesium chloride, which pollute streams that run into rivers that feed municipal water supplies.
Winter weather de-icing chemicals add their “two cents worth” to the contamination of the second-most-important and precious commodity of life,
The foremost “life-giver” is air with oxygen and other gases , now so terribly horribly contaminated that it’s not fit to breathe by man, mouse, or any mammal! Whom do we have to thank for that? Technology?
If that’s not enough, consider all the heavy duty, caustic chemicals we pour down the kitchen sink and other drains to unclog them. In most cases, humans downstream from sewage processing plants or rivers drink those polluted waters, which are “treated” further by municipal water treatment plants  with flocking agents like aluminum, etc. and other chemicals (including fluoride) to “clean”—or shall I say—add more chemicals to deliver ‘potable’ water!
How about all the prescription drugs that are disposed of by flushing down the toilet?  Inadvertently, consumers drink more prescription drugs in their municipal water than we may realize! [12, 13]
On top of all the above, we must include innumerable herbicides we spray on our lovely green lawns! Where do those chemicals go? Answer: Into the earth to ‘feed’ grass roots, but also finally wind up in underground aquifers .
It reminds me of the line from the poem, The Rime of the Ancient Mariner: “Water, water, everywhere, Nor any drop [fit] to drink.” 
There probably are some sources of water contamination I omitted, but let’s move on to other contaminants such as toxic metals in pharmaceuticals, especially vaccines: aluminum [19, 20] in four formulations, ethylmercury in the form of Thimerosal, formaldehyde, polysorbate 80 and a laundry list of toxic chemicals  including colors and dyes, antibiotics, detergent, foreign DNA, animal products, mycoplasmas, and human diploid cells (aborted fetal cell lines). Here’s a short crash course video on what mycoplasmas do in the human body.
Many cosmetics and ‘beauty’ products like lipstick contain lead !
How about all the toxic chemicals, additives, preservatives, food colors, and other unknown ingredients like nanoparticles  that we don’t even know we eat! Titanium dioxide!
All the above contribute to what I for many years have called “toxic body syndrome” that I discuss in my new book Eat to Beat Disease, Foods Medicinal Qualities, which will be available on Amazon.com within the next couple of weeks.
Instead of technology creating more health hazards, toxins and chemicals, shouldn’t technology, business and industry get their acts together and devise means and methods to clean up the mess they made of Planet Earth rather than trying to colonize Mars, which technology-savvy earthlings probably will contaminate too?
