Ohio study tracks air pollution from fracking

A new study raises more questions about public health risks in oil and gas development zones.

Findings confirm health risks to people living near oil and gas wells

Staff Report

FRISCO — Careful air sampling near active natural gas wells in Carroll County, Ohio showed the widespread presence of toxic air pollution at higher levels than the Environmental Protection Agency considers safe for lifetime exposure, according to scientists from Oregon State University and the University of Cincinnati.

The study reinforces the need for more extensive air quality monitoring in fracking zones around the country, where exposure to the poisonous emissions are likely to lead to increased risk of cancer and respiratory ailments. Continue reading

Environment: New analysis helps pinpoint fracking pollution in Pennsylvania drinking water

Fracking substances found almost two miles away from faulty drilling operation

Staff Report

FRISCO — Scientists in Pennsylvania said they’ve been able to track pollution from fracking as the source of contamination in drinking water wells more than 1 mile from the fracked shale gas wells.

The stray natural gas and wastewater moved laterally along shallow to intermediate depth fractures to the source of the homes’ well water. The chemicals foamed from water faucets in three homes near a reported well-pad leak. The homes were sold to the gas company as part of a legal settlement in 2012, but scientists received samples before the transfer.

Previous studies had not been able to identify the cause of the foaming, but the new analysis found a chemical compound, 2-BE, and an unidentified complex mixture of organic contaminants, both commonly seen in flowback water from Marcellus shale activity.  Continue reading

Scientists say they’ve found ‘most polluted bird’

FRISCO — Better living through chemistry may — or may not — be an apt motto for people. But it definitely doesn’t hold true for wild animals, who, to their detriment, ingest the toxic remnants of our industrialized society on a daily basis.

This trickle-down effect was recently illustrated once again as Canadian scientists announced that they found what they called  “the most polluted wild bird that has been found anywhere in the world.” Continue reading

Environmental groups slam McConnell-led Senate

100 days of pain …

Staff Report

FRISCO — A furious assault on the environment during the first 100 days of a GOP-controlled Senate has environmental advocates on the defensive.

Instead of making progress on climate change and other key conservation issues, progressives are in the position of trying to hold the line on gains they made during the first six years of the Obama administration.

According to a coalition of advocacy groups, Senate Majority leader Mitch McConnell has made it clear that his top priority is protecting polluters and dismantling clean air and public health protections. Continue reading

Environment: Blacktop runoff is deadly to stream life

Coal-tar sealant fingered as highly damaging to DNA

Staff Report

FRISCO — New research led by U.S. Geological Survey scientists shows that pavement sealants made with coal tar are highly toxic. Runoff from surfaces treated with such sealants can kill fish and other stream organisms for months after it’s applied, the researchers concluded in a pair of recent studies.

Pavement sealant is a black liquid sprayed or painted on the asphalt pavement of parking lots, driveways and playgrounds to improve appearance and protect the underlying asphalt.

Pavement sealants that contain coal tar have extremely high levels of polycyclic aromatic hydrocarbons (PAHs).  Coal tar is a known human carcinogen; several PAHs are probable human carcinogens and some are toxic to fish and other aquatic life. Continue reading

FRISCO — Antarctica is often described as one of the last pristine environments on Earth, but that may be changing as human activity increases.

Researchers with the Australian Antarctic Division recently said they tracked pollutants from common household sources dispersing from a research station into the surrounding environment. As a result, the scientists are rethinking how they store and dispose of materials that could be the source of pollutants. Continue reading

Environment: Deep-sea fish not immune to pollution

New study finds liver damage and tumors in fish living a mile deep off the coast of France

Even fish living deep in remote oceans are tainted by pollution.

Staff Report

FRISCO — As big and as deep as Earth’s oceans are, they’re still feeling the sting of human-caused pollution. Even a mile down, some fish have liver pathologies, tumors and other types of health problems that are often linked with exposure to toxic chemicals and carcinogens, according to a new study conducted in the Bay of Biscay, off the coast of France.

The study also discovered the first case of a deep water fish species with an “intersex” condition, a blend of male and female sex organs. The sampling was done in an area with no apparent point-source pollution, and appears to reflect general ocean conditions.

“Deep in the ocean one might have thought that the level of contamination and its biological impact would be less,” said Michael Kent, an Oregon State University microbiologist who co-authored the new study. “That may not be the case. The pathological changes we’re seeing are clearly the type associated with exposure to toxins and carcinogens,” said Kent, one of the study’s co-authors. Continue reading
