This week, the Environmental Working Group (EWG) released a report titled Erin Brockovich Carcinogen in Tap Water of More Than 200 million Americans.
The nonprofit organization’s study analyzed chromium-6 sampling data collected by water systems throughout the U.S. between 2013 and 2015, and found that approximately 75 percent of the samples tested contained chromium-6 at levels at or above California’s Public Health Goal (PHG) of 0.02 parts per billion.
It is important to note that the State of California’s Office of Environmental Health Hazard Assessment sets the Public Health Goal for known carcinogens such as chromium-6, “At a level that not more than one person in a population of one million people drinking the water daily for 70 years would be expected to develop cancer as a result of exposure to that chemical.”
A Public Health Goal is not a boundary line between a “safe” and “dangerous” level of a chemical, and drinking water is frequently demonstrated as safe to drink even if it contains chemicals at levels exceeding their Public Health Goals. Learn more about Public Health Goals.
Helix monitors for chromium-6 annually. Our most recent test results were 0.021 parts per billion. Our 2014 test results ranged from Non Detected (ND) to 0.049 parts per billion.
Chromium-6 is a heavy metal. It occurs naturally in California’s rock and soil and can enter the water supply through erosion. It can also leach into groundwater from industrial sites. Chromium-6 is used in textile dyes, wood preservation, leather tanning and anti-corrosion coatings.

The California Special Districts Association (CSDA) is hosting a video competition as part of its “Districts Make the Difference” public outreach campaign for all California high school and college students.
In an effort to increase the understanding and awareness of special districts, students are encouraged to learn more about special districts and enter the contest by creating a 60-second video.
Submissions will be accepted until October 31, 2016 at which point five finalists will be selected and featured on the Districts Make the Difference website for statewide voting.
Starting November 1, the public will have the opportunity to vote for their favorite video and the top three winners will receive scholarship prizes. First place will receive $2,000, second $1,000, and third $500. Additional finalists will also receive a $100 gift card.
We would like your help in reaching out to students.
Below are three easy ways you can help us in our efforts:

Do you wish you were going somewhere this weekend? Then read this post, which takes you on a raft deep into the Grand Canyon, and takes you back to your college days, as well.
Each spring, graduate students in geology, ecology and hydrology at UC Davis (University of California) end the semester by rafting over a 100 miles down the Colorado River and through the Grand Canyon — to experience and talk science. This year, they brought with them a writer, a photographer and a few GoPro cameras to document the journey. They produced an immersive reading experience with audio, video and stunning photography that makes you feel like you’re there.
