DRILLING FLUIDS AND THE ARCTIC TUNDRA OF ALASKA: ASSESSING CONTAMINATION OF WETLANDS HABITAT AND THE TOXICITY TO AQUATIC INVERTEBRATES AND FISH (JOURNAL VERSION)
Drilling for oil on the North Slope of Alaska results in the release of large volumes of used drilling fluids into arctic wetlands. These releases usually come from regulated discharges or seepage from reserve pits constructed to hold used drilling fluids. A study of five drill sites and their reser...
