Lakes with zebra mussels have higher level of blue green toxins

Inland lakes in Michigan that have been invaded by zebra mussels, an exotic species that has plagued bodies of water in several states since the 1980s, have higher levels of algae that produce a toxin that can be harmful to humans and animals, according to a Michigan State University researcher. In a paper published in… Continue reading Lakes with zebra mussels have higher level of blue green toxins

Invasive Spiny Waterflea Confirmed in Indian Lake

Keene Valley, NY – Spiny waterflea, an invasive zooplankton, continues to spread in the Adirondacks. First discovered in Great Sacandaga Lake in 2008 it has quickly spread into at least eight other lakes in the region. Most recently, a new population was detected in Indian Lake (Hamilton County). Up until this detection, Indian Lake was… Continue reading Invasive Spiny Waterflea Confirmed in Indian Lake

HABs & carcinogens in Florida rivers 

A deluge of benzene, beryllium, trichloroethane, dichloroethylene and other known carcinogens ought to blend nicely with the stinking layers of Day-Glo green algae that has been sliming the St. Lucie River and threatening the Caloosahatchee River. Or with the massive fish kills along the Banana River, Sykes Creek, the Indian River and the Mosquito Lagoon.… Continue reading HABs & carcinogens in Florida rivers

New Guide to Help Identify Harmful Algal Blooms

To assist Native American and Alaska Native communities, U.S. Geological Survey (USGS) scientists developed a guide to evaluate algal blooms for the presence of cyanobacteria that are known to produce a variety of toxins. Because many Native American and Alaska Native communities are dependent on subsistence fishing, they may have an increased risk of exposure… Continue reading New Guide to Help Identify Harmful Algal Blooms

EPA Publishes Draft Aquatic Life Criteria for Copper in Estuarine/Marine Waters

EPA is soliciting public comment on draft aquatic life criteria for copper in estuarine/marine waters. The 2016 draft criteria incorporates a recently-developed saltwater biotic ligand model and the latest scientific information for estuarine/marine aquatic organisms. The model allows users to develop protective chronic and acute values based on site-specific water quality variables including temperature, dissolved… Continue reading EPA Publishes Draft Aquatic Life Criteria for Copper in Estuarine/Marine Waters
