EARTH, WIND, and FIRE-Chromium on Polk?

Did you see today's news story about the chromium 6 plume in California which has grown and migrated until it covers two miles, contaminating numerous wells? This, by the way, is the famous Erin Brockovich contamination situation updated with latest info. See current story at http://www.desertdispatch.com/news/hinkley-9653-lower-showing.html
CHROMIUM...Hmmm. Prevents rust, hardens and coats steel, and creates yellow and green colored pigments, among other things.
Chromium along with lead and toluene has long been a major problem at the Polk St Dixico site in Oak Cliff. And, yes, the word "plume"- pooled excess chemicals - is included in the Dixico records.
If you or a loved one has cancer, and has lived near this plant, I would research Dixico Inc (Dallas) toxic release info-requesting Dixico records from EPA and TCEQ. Several documents and request forms can be found online- but the entire story would require a book- or in my case, a garage full of boxes.

Water is not the only worry at Dixico-maybe not even the primary one. Waste solvents-benzene, xylene, MEK, alcohols, and worse - as well as plastics with dioxins-were INCINERATED for years on S Polk-filling the air with carcinogens for possibly 50-60 years.
This plant offered multiple pathways for chemical exposure: soil, groundwater, the creek, the sewer system, the air...and all in a RESIDENTIAL NEIGHBORHOOD!
What were we thinking to allow families and carcinogens to co-exist a few feet from one another?
Where were our city fathers with zoning capability and responsibility?
In offices thinking about how Dallas needed Dixico's 250+ jobs, while citizens prevented Dixico from becoming a large scale toxic waste incineration center. (Thank God for citizens with common sense and self-preservation ability.)
Yes, we Texans need industry and goods and jobs-but not poisonous ones in our backyard or neighborhood greenbelt.
Dear reader/friend, I hope you grew up far, far away from Dixico-and I wish my deceased schoolmates had. I wish Dixico had been light years from Winnetka Heights, Winnetka School, and Greiner Jr. High; that lovely old, sheltering Oak Cliff had never heard of laminating potato chip bags with petroleum-based ink and adhesive.
Dixico, from an environmental standpoint, is a disaster that never should have happened anywhere; but especially not next door to Cedar Creek and the Elmwood residential neighborhood of OC.
