Lake Pollution in the News
From the Danbury News-Times, July 28, 2019
A study will examine how to stave off the nutrients that cause these invasive plants to grow in the water.
The research will determine the best way to prevent these nutrients from entering the water through septic systems. This is key to preserving the lake, said Nelson Malwitz, chairman of the Brookfield Water Pollution Control Authority, which is conducting the study.

Lake Hopatcong 2019 – The Largest Lake in NJ – Closed for Summer
Elevated bacteria levels continue to be found in the remainder in the lake, one month after DEP advised against swimming, jet skiing, kayaking, canoeing, wind-surfing, paddle-boarding and fishing due to the presence of harmful algal bloom, or HAB.
Bacteria in the blooms can cause a skin rash if touched. If the water is consumed, it can cause abdominal pain, headaches, vomiting, nausea, and blistering around the mouth and flu-like symptoms, health officials have said.
LAKE HOPATCONG, N.J. — August 7 — Around Lake Hopatcong, New Jersey’s largest lake, workers have been laid off, sailing lessons canceled and summers ruined. The reason: clouds of electric-green algae in the water, blooming in quantities never before recorded. [More from The Citizen’s Voice …]
According to a June 2016 Wall Street Journal article a growing list of states ramping up efforts to control potentially toxic algal blooms that are fouling water supplies and making summer swims dangerous in lakes, ponds and reservoirs.
Microbiologists say … growing population and changing land use practices are culprits in the rise. The algae blooms have hurt real-estate values in his lake-front community and businesses.
Joe Cornely, a spokesman for the Ohio Farm Bureau Federation, said the group is cautiously supportive of the state’s plan, which also seeks to address … bad septic systems.
(Notice right how the algae bloom is most pronounced near a population of septic systems.
In another example in 2015 an algal bloom stretched for 500 miles along the Ohio River, the biggest ever.
Wisconsin has set the most stringent maximum limits for phosphorus in rivers, lakes and reservoirs. Last month, roughly 60 local governments around Madison agreed to pool $2 million annually for the next 20 years to pay for measures to keep phosphorus out of rivers.
Iowa lawmakers sought ways this spring to curb nitrates and phosphorus but failed to pass any measures. The state was forced to close beaches at parks in record numbers last summer because of algal blooms that can make swimmers and even dogs sick when they ingest the water, and that irritate the skin after swimming. A Des Moines water utility has also sued three counties over high nitrate levels in a potentially precedent-setting case that seeks to hold local governments accountable for drainage issues.
The EPA is planning to introduce a mobile app to alert people about potentially dangerous blooms in their areas.
“Things are getting worse,” said Raphael Kudela, a phytoplankton ecologist at the University of Southern California. He noted that last summer an algal bloom off the West Coast, stretching from central California to Alaska, was the area’s most severe on record.
In recent years, warmer temperatures have increased the time algae can grow and more intense storms have caused more phosphorus and other nutrients to be washed off urban and agricultural lands, according to the federal EPA. Shallow area of lakes are warm which encourages algae proliferate.
