New York has asked the Environmental Protection Agency to bar boaters from dumping treated sewage into Lake Ontario. Proposal affects even discharge of sewage treated with on-board devices.
A system using satellite images and current predictions warns water treatment plant operators when to treat water to avoid four odors and taste. Now the forecasts are available to the public to help make swim decisions.
Legislation has passed and enforcement tightened. Yet leaking septic tanks continue to threaten human and environmental health.
The lack of funds to fix them remain a hurdle.
Ill maintained, leaky and overflowing septic tanks are polluting drinking water sources, rivers and lakes and causing serious health concerns in Great Lakes communities. AUG. 16
Leaky pipes: Researchers find sewage in most Milwaukee stormwater discharges
A recent study found almost 90 percent of storm water outfalls tested in Milwaukee contained human sewage
JULY 7:
Michigan on-site wastewater systems lack state oversight
When it comes to regulating septic systems, Michigan is a loner. It lacks statewide regulations to oversee the permitting and operations. JUNE 28:
Local governments search for funds to fix failing septic systems
Leaking septic tanks continue to threaten human and environmental health despite increased regulations, legislation and enforcement.
A new federal report says it’s cheaper and easier to test water quality from space than it is from a boat or a dock. Data gathered by hand can be extrapolated to satellite imagery.
It’s an important advance in lake-heavy regions where it is expensive and challenging to visit every body of water.
Still, gathering data the old-fashioned way is not obsolete.
Heavy rainfall often overflows Detroit sewers, dumping untreated human and industrial waste, toxic materials and other debris into streets and waterways.
Separating sanitary and storm systems is costly and time consuming. So Detroit is tackling water before it hits the streets.
To contribute to the discussion about the climate change section of the Great Lakes Water Quality Agreement, post your thoughts below. If you want the U.S. and Canadian governments to consider your input, send it to the official website. Currently, the GLWQA does not address the impacts of climate change. During the GLWQA Review period, there was general agreement that the GLWQA should be revised to specifically address pressing threats to the Great Lakes, including the impacts of climate change. Recommendations included the need to understand and predict future climate changes in the Great Lakes system, including an assessment of potential impacts and vulnerabilities.
To contribute to the discussion about the ship-source pollution section of the Great Lakes Water Quality Agreement, post your thoughts below. If you want the U.S. and Canadian governments to consider your input, send it to the official website. Requirements for the Parties under the current GLWQA related to ship-source and shipping-related discharges and emissions are specified in separate Annexes:
Annex 4 — Requirements for Oil and Hazardous substances discharges
Annex 5 — Garbage, Sewage and Cargo Residues
Annex 6 — The potential for discharge of Aquatic Invasive Species from ballast water is mentioned, as well as the requirement to review and report on pollution from shipping sources, consult with the IJC, and study any potential pollution problem from ships identified by the Parties
Annex 8 — sets out requirements for Onshore and Offshore Oil Handling Facilities but specifically exclude vessels
Annex 9 — sets out requirement for a joint contingency plan in response to oil spills
1. Ship Air Emissions
The current GLWQA deals with the following ship-source discharges that could have negative effects upon the water quality of the Great Lakes: Annex 4 for Oil and Hazardous Pollution Substances; Annex 5 for Sewage and Garbage (Ship Generated Garbage and Cargo Residues); and Annex 6 for Invasive species in Ballast Water. Both Canada and the United States have compatible regulations for the discharges that are identified in the current GLWQA that are based on International Conventions.
To contribute to the discussion about the toxic substances section of the Great Lakes Water Quality Agreement, post your thoughts below. If you want the U.S. and Canadian governments to consider your input, send it to the official website. Both Canada and the United States recognize that improperly managed chemicals pose unacceptable risks to health and the environment in their jurisdictions. Both countries are committed to managing chemicals effectively and to reducing risks from chemicals to acceptable levels. While certain persistent toxic substances (PTS) have been significantly reduced in the Great Lakes Basin Ecosystem over the past 30 years, they continue to be present at levels above those considered safe for humans and wildlife, warranting fish consumption advisories in all five lakes and connecting channels.
To contribute to the discussion about the nutrients section of the Great Lakes Water Quality Agreement, post your thoughts below. If you want the U.S. and Canadian governments to consider your input, send it to the official website. In Lake Erie, the re-occurrence of wide spread algae blooms has been observed in recent years. In Lakes Michigan, Huron and Ontario the algae problem is limited to the nearshore zones. Algae are not generally a problem in Lake Superior.
