The study looked at eleven herbicides and insecticides consistently in Illinois, Indiana, Iowa, Nebraska, Ohio, and neighboring states, an area known as the Corn Belt region.

Clean Water Act Violations Rarely Prosecuted
Posted on Sep 16, 2009 by Jennifer Lance.
In an extensive series on “toxic waters”, the New York Times has discovered that “more than 50 percent of regulated facilities violated the Clean Water Act (CWA), but enforcement actions against polluters were infrequent.” Hawaii has the greatest number of violators per 100 facilities; Nevada has the least. Missouri is the state with the least number of enforcements for violations.

Massive Australian Oil Rig Spill to Continue for Two Months
Posted on Sep 03, 2009 by Jennifer Lance.
A massive oil spill occurring off the northwest coast of Australia is predicted to continue for two months before the leak is plugged. An oil rig in the Timor Sea, owned by Thai company PTTEP, began seeping oil on August 21. The multi-million dollar clean up will take eight weeks under the salvage plan. In order to stop the oil leak, PTTEP is bringing in another oil rig from Singapore. The Age reports:
PPTEP spokesman David Tasker confirmed it could be up to eight weeks before the leak is stemmed – more than three weeks to put the second rig in place and four weeks of drilling before it could tap the well…A fracture in the well, more than two kilometres below the surface, is suspected of causing the leak.

Superfund Hudson River Dredging Resumes After Dangerous PCB Levels Detected Downstream
Posted on Aug 13, 2009 by Jennifer Lance.
200 miles of the Hudson River were classified as a Superfund site in 1984. The Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) established the Superfund program to clean up abandoned hazardous waste sites. The Hudson River was contaminated by two General Electric (GE) capacitor production plants. From 1947-1977, “between 209,000 and 1.3 million pounds of PCBs were released into the Hudson River”. The Superfund clean up of the Hudson River was halted on August 7, 2009 due to dangerous levels of PCBs downriver from the clean up sites but resumed on August 11.
