Chromium-6, the cancer-causing chemical best known for its role in the Erin Brockovich story, has been found at higher-than-recommended levels in the tap water supplying two-thirds of all Americans, according to a report from the Environmental Working Group.
EWG, a nonprofit research organization, analyzed Environmental Protection Agency data on more than 60,000 samples collected at water utilities in all 50 states between 2013 and 2015. They found chromium-6 at levels deemed unsafe by public health officials.
“Americans deserve to know if there are potentially harmful levels of a cancer-causing chemical in their tap water,” David Andrews, a senior scientist at EWG and co-author of the report, told the PBS NewsHour.
Chromium-6 occurs naturally in the environment, but high quantities are also produced by industrial projects. Pollution can occur when these industrial sites fail to follow proper waste disposal methods, such as with unlined coal ash ponds.
“The difficulty with chromium-6 is how to set a standard to protect human health during windows of development,” Andrews said.
Even in small amounts, chromium-6 can cause skin burns, pneumonia, complications during childbirth and stomach cancer.

Businesses could earn hundreds of billions of dollars a year by 2030 by investing in better agriculture and food ranging from micro-irrigation of crops to reduced waste, an international study said on Friday.
A commission including chief executives of Unilever and Aviva as well as academics and civil society groups said companies could exploit U.N. plans to end poverty and hunger and protect the planet by 2030.
“Instead of treating it as ‘Oh my God, another huge global problem to worry about’ … you can break it down into chunks of real business possibility,” Mark Malloch-Brown, chair of the Business and Sustainable Development Commission, told Reuters.
The Commission, launched in January, said businesses could unlock about $2.3 billion a year in food and agriculture sectors by investing $360 billion a year to help achieve the U.N.’s Sustainable Development Goals for 2030.
It listed opportunities in 14 areas including farming technology, restoring land and forests, urban agriculture, irrigation, aquaculture and better packaging. Continue reading “Big farm opportunities seen for business in 2030 U.N. goals”
A new study from the University of Exeter, published in the journal Ecology Letters, found that phytoplankton — microscopic water-borne plants — can rapidly evolve tolerance to elevated water temperatures. Globally, phytoplankton absorb as much carbon dioxide as tropical rainforests and so understanding the way they respond to a warming climate is crucial.
Phytoplankton subjected to warmed water initially failed to thrive but it took only 45 days, or 100 generations, for them to evolve tolerance to temperatures expected by the end of the century. With their newfound tolerance came an increase in the efficiency in which they were able to convert carbon dioxide into new biomass.
The results show that evolutionary responses in phytoplankton to warming can be rapid and might offset some of the predicted declines in the ability of aquatic ecosystems to absorb carbon dioxide as the planet warms.

Seeds are the plant equivalent of an armoured vehicle. They carry the offspring of plants out into the dangerous world and protect them until the time is right for them to grow into new plants. The…

A sinkhole spanning 45 feet (13.7 meters) in diameter opened at a Mosaic Co phosphate fertilizer facility in Florida, leaking 215 million gallons of “slightly radioactive water,” a company spokesman said on Friday.
Mosaic said the monitoring system at its New Wales facility at Mulberry, Florida, showed a decline in water levels on Aug. 27 from the retention pond of a phosphogypsum stack, a hill of hazardous waste. Phosphogypsum is a radioactive byproduct resulting from the production of phosphate.
The Minnesota-based company immediately reported the incident to state and federal environmental authorities, Mosaic spokesman Ben Pratt said on Friday. But it did not otherwise report it publicly until posting information on its website on Thursday, he said.
The leaked water is enough to fill more than 300 Olympic swimming pools.
The nearly three-week gap between detecting the sinkhole and reporting it to the public is alarming, said Jacki Lopez, Florida director of the Center for Biological Diversity.
“It’s hard to trust them when they say ‘Don’t worry,’ when they’ve been keeping it secret for three weeks,” she said.

Take a look at this amazing resource I’ve just discovered, it’s Dr Elaine Inghams lessons on the soil food web, as well as creating your own composts and compost teas/extracts. The information contained hereinafter is often behind a paywall.
“Elaine Ingham, Chief Scientist at Rhodale Institute came to Hawi, Hawai’i in July 2012 to deliver a 5 day seminar dedicated to studying, understanding, and improving our soil biology to assist in ecologically sound agricultural practices. This is where I got my introduction to the microscope and learned much of it’s importance. This was some of the best 30 hours of class ever, and I often re-watch this epic series to refresh myself and discover more as I tune my own magnification of understanding this microscopic wonderland.” – Drake of Natural Farming Hawaii.

“Neem seed cake also reduce alkalinity in soil, as it produces organic acids on decomposition. Being totally natural, it is compatible with soil microbes, improves and rhizosphere microflora and hence ensures fertility of the soil. Neem Cake improves the organic matter content of the soil, helping improve soil texture, water holding capacity, and soil aeration for better root development.” – Wikipedia
There it is, another added benefit of the Neem Cake is its ability to create a favourable growing environment on the more alkaline soils. So not only are you getting an excellent source of organic nutrients and the “pest and disease resistance” it’s also working as a soil conditioner too.
The below shows how soil PH affects the availability of nutrients to the plants, it’s useful as a general guide.
