Being aware of what’s in our water is essential to our health and survival. With that awareness there are many things we can do to improve the water we consume. But what if individuals or large groups of people are not aware that they are consuming contaminated drinking water? Environmental laws are usually enacted to stop some adverse pollution but that does not make it all go away overnight. Some chemicals never go away and are labeled ‘forever chemicals’ or lack scientific data and are classified as ‘emerging contaminants.’

People must take action to help themselves, their family, community, to gain awareness. Cleanliness is next to godliness and fortunately by the grace of God there are people in the world willing to fight for safe water. The Environmental Working Group is a non-profit organization spreading awareness of what’s in our food and water for almost 30 years. To find out what’s in your drinking water and what types of filtration systems can be used to treat the water check out EWG Tapwater.

They also provide an interactive map in the U.S. on hexavalent chromium (Cr +6) contamination popularly known as the ‘Erin Brockovich’ chemical listed as tainting the tap water of 251 million Americans.

You may recall the movie staring Julia Roberts portraying Erin Brockovich in her quest for helping a small California town become aware of Pacific Gas and Electric (PG&E) contaminating people’s drinking water.

It’s an amazing true story and I have some related personal experiences to share. For about one year I worked as an environmental scientist contractor to PG&E which was about five years after the movie was released. Because of the largest civil lawsuit in history costing PG&E $333 million as well as tremendous damage to their reputation and harm caused to many people, I observed they became very proactive in cleaning up remaining contaminated sites. I did not work on Cr +6 issues related to gas compressor stations but focused on electrical substations and transmission systems in the San Francisco Bay area. I led a team to remove underground pipelines containing transformer cooling oil that potentially contained PCBs. We removed contaminated soil containing arsenic that was used as an insecticide in the mid 1950’s. Power transmission lines built on landfills were subsiding needed urgent repairs. I monitored air quality at a substation construction site next to a school to make sure semi-volatile compounds disposed many decades ago in the soil did not spread.

Check out the recent Brockovich book (which I did at the local library) and found it very informative and relatable on why water supplies get contaminated, how they are affecting peoples health, and what we can do to take action. Here’s an interesting NPR review of the book.
