Nano-bubble pilot project in Tijuana River called ‘a waste of money’ after equipment swept away during storm
The International Boundary and Water Commission has acknowledged that its heavily criticized $2.5 million “nano-bubble” project in the Tijuana River was destroyed and swept away during a recent storm. On September 9, the IBWC launched the controversial technology, hoping it would clean up sewage and chemical contamination in the Tijuana River, where daily readings of gases such as hydrogen sulfide are detected. Critics, including several politicians, scientists and environmental groups, have said the method has not been proven effective or safe for humans. … The federal agency claimed it and its contractor “are evaluating the data collected and hope to share the results of the project soon.”
