EPA Issues New Recommendations for Recreational Water Quality Criteria and Swimming Advisories for Cyanotoxins

Published: 09 September 2019
Based on the latest scientific information, the U.S. EPA has established recommended water concentrations, at or below which protects public health, for the cyanotoxins microcystins (8 micrograms per liter) and cylindrospermopsin (15 micrograms per liter). EPA’s recommendations are protective of all age groups and are based on peer-reviewed and published science.

The Rainy River – A Case Study in Pollution and Recovery

Published: 04 July 2019

Fibre mats in the Rainy River downstream of the mills, 1952The history of the Rainy River is fascinating. How could it not be with voyageurs and lumberjacks all tangled up in it. The overlooked part of any history lesson, however, is often the timeline of environmental insults that occurred in concert with the industrial revolution and the population of the land and exploitation of its resources.

In this article, Bev Clark explores the history of the pollution and subsequent research and cleanup of the Rainy River as an example that shows what coordinated international efforts engaging the IJC can achieve.

Buoyed By New Clues to Lake of the Woods

Published: 24 July 2019

Adam Heathcote collects a suspended sediment sample from a buoy station on Lake of the Woods.Phosphorus, algae’s favorite food, should be quickly buried by inches of mud year over year.  Perhaps, somehow, the phosphorus that had entered the lake during the paper and population booms of the mid-twentieth century is being recycled?  Could it be that the turbulent waters of Lake of the Woods south basin (the Big Traverse) are combining with short periods of temperature stratification (when the cold bottom waters of a lake do not mix with the warmer water above) to deplete oxygen and draw nutrients back up from the sediments. Particularly windy days could then mix nutrient rich particles of sediment throughout the water column, allowing pollution from many years ago to be reused over and over again. In this article from the Field Notes - Stories from the St. Croix Watershed Research Station of the Science Museum of Minnesota the story unfolds of research seeking to answer these questions and gain insights into what causes the algae problems plaguing Lake of the Woods.

Zombie Phosphorus: The Long-Term Consequences of Nutrient-Rich Runoff

Published: 23 July 2019

robert dietz glacial lakes 300In lakes throughout the upper Midwest, from giant Lake of the Woods to dozens of smaller lakes in our urban and agricultural landscapes, clean water has not obviously followed pollution reductions.  The complex connections between land, water, climate, chemistry, algae, and even fish can conspire to make us pay a high price for past sins.  This article from the Field Notes - Stories from the St. Croix Watershed Research Station of the Science Museum of Minnesota examines the role of "legacy" phosphorus in the lake bottom and other factors in recovery of lakes from too much nutrient pollution.

Studies of Lake of the Woods show how water can struggle with a legacy of pollution

Published: 24 July 2019

lake of the woods boating through green water 640Spanning the U.S.-Canada border at the northern extremity of Minnesota and the northwestern corner of Ontario, vast Lake of the Woods has a storied relationship with humans: as home, as highway, as getaway. Lake of the Woods is well-loved, and troubled. This article from Field Notes -Stories from the St. Croix Watershed Research Station examines the history of pollution and how research studies are improving out understanding the lake’s past and current conditions, including how phosphorus is stored and returned from the lake bottom.  These studies are helping us to figure out what forces affect the water quality today -- which is essential to setting clean-up goals and identifying the most effective ways to achieve them.
