for more complete stories included in the Water News. Also some advertising containing info on water filters, but the articles about water make skipping over the adverts ok by me.

National water news featured flooding in some areas, record heat and drought in others, ravaging wildfires in California, and broken water mains across the nation.
Toxic blue-green algae has bloomed again in Lake Okeechobee, Florida's largest lake. An outbreak so severe that Governor Rick Scott has declared a state of emergency in seven counties. While the term "algae bloom" might not sound dangerous, it amounts to an outbreak of cyanobacteria that presents a signficant risk to public health.
The Bluebird K-7 Floats Again, After More Than Fifty Years
Bluebird, the hydroplane that reached record-breaking speeds, has returned to the water for the first time in more than 50 years since it crashed killing its pilot, Donald Campbell. The jet-powered boat was launched in a lake on Isle of Bute in Scotland on August 4, 2018.
Having broken eight world-speed records on water and land in the 1950s and 1960s, Campbell was attempting to break his own water-speed record of 276 mps when he was killed. The wreckage of Bluebird, with Campbell's body, his race suit still intact, was pulled from the depths of the Cumbria Lake in 2001. The boat was restored by volunteers.

Scientists announced that the sea surface temperature off the coast of La Jolla, California came in at 78.6 degrees Fahrenheit - the warmest it's ever been in the 102 years of recorded measurements. Earlier in the week, the National Weather Service (NWS) in San Diego recorded the sea surface temperature at 80 degrees Fahrenheit, a few miles north off Solana Beach. One NWS meteorologist said, "It's over the top. It's making the nights warmer, the days muggier, and the sea breeze doesn't mork as well as it usually does."
According to science journal, Nature, police in the southern Chinese city of Zhongshan are monitoring waste water to evaluate the effectiveness of drug-reduction programs and to track down and arrest manufacturers of illegal drugs.
In what is regarded as the biggest dam removal project in U.S. history, a plan is underway to remove simultaneously four hydroelectric dams from the Klamath River. The dams have been blamed for failing populations of wild fish runs, such as salmon and steelhead, as well as exacerbating water quality problems in the river.
There is a plan in Lincoln, Nebraska to provide free replacement of lead service lines leading into residents' homes in order to avoid any future problems with lead in the city's drinking water. The $21 million plan would replace lead pipes for about 3,000 homes built before 1950 over a period of 14 years.
Only 43 percent of school districts in the United States tested for lead in drinking water used by students in 2016 or 2017, according to a report from the U.S. Government Accountability Office.
Research conducted by LSU Health New Orleans School of Public Health finds that the old standby recommendations for running water to flush out lead in residential water pipes are not consistently effective and may not be the best way to protect children from lead in drinking water. The study recommends other lead exposure interventions, like certified water filters, especially if it's not financially possible to replace water lines.
Widespread testing for PFCs is being conducted in Michigan. Environmental officials are more than halfway through testing over 1,380 community water supplies for certain contaminants. So far, some 650 water supplies have been found to have water that exceeds the federal recommendation of 70 parts per trillion. For example, the water supply for the city of Parchment and neighboring Cooper Township was found to have 1,587 parts per trillion of PFAS, more than 20 times higher than the U.S. Environmental Protection Agency's health advisory for perfluoroalkyl (PFAS) and polyfluoroalkyl contaminants (PFOS). The city placed them under a state of emergency after officials warned residents not to drink the water or to cook with it.
A recent article warns that while manganese in water has been regarded as a nuisance rather than a health threat, there is growing evidence that, in significant amounts in well water, it can be associated with lowered IQ of children and other health issues. Most health problems with manganese seem to be related to diet and inhalation (one study, for example, shows that welders are particularly at risk for manganese-related ailments). Just 0.05 parts per million manganese in water can cause staining and odors, so ingesting large amounts from well water doesn't seem too likely.
