Lawmakers Take Manufacturing Companies to Task Over Toxic PFAS Chemicals in Drinking Water
Tensions between lawmakers and several large manufacturing companies came to a head on Capitol Hill this week during a hearing on toxic fluorochemicals in U.S. drinking water.
Representatives from the 3M Company, the Chemours Company and DuPont appeared before the House Oversight and Reform Committee on Sept. 10 as Congress explores several bills to regulate dangerous "forever chemicals" called PFAS, which do not break down in the environment and have been linked to a number of diseases.
Democrats on the committee suggested the companies had long known about the health hazards of dangerous "forever chemicals" called PFAS in their products and should shoulder some of the responsibility for addressing their spread.
"You have played a part in this national emergency. You have sickened our first responders and members of the military, and I don't know how you sleep at night," said Rep. Debbie Wasserman-Schultz of Florida, The Hill reported.
California Rep. Harley Rouda, who chairs the Oversight and Reform Committee's Subcommittee on Environment, said the companies' misrepresentation of the science around PFAS "shakes the foundation of democratic capitalism" by "violating the trust of the American people," The Guardian reported.
According to the U.S. Environmental Protection Agency, PFAS are synthetic chemicals used since the 1940's in food packaging, non-stick pans, cosmetics, firefighting foam and water- and grease-repellent products. PFAS contamination is often found in water sources near industrial sites, military bases and airports in nearly every U.S. state.
In addition to persisting in the environment, they have been shown to accumulate in the human body, and PFAS exposure has been linked with infertility, cancer, thyroid disease, developmental problems in children, liver damage and a host of other health issues, according to the U.S. Agency for Toxic Substances and Disease Registry.
"Exposure to PFAS at even the lowest concentrations has been shown to harm human health and puts people in communities with contaminated drinking water at risk," the Environmental Working Group found.
The company executives, defended by the committee's Republican members, downplayed the health risks of PFAS and corporate liability for cleanup and medical costs.
3M's Senior Vice President of Corporate Affairs Denise Rutherford testified that the company had voluntarily phased out use of certain types of PFAS in the 90's and that "there is still no cause and effect relationship for any adverse human affect" of PFAS at current levels, The Hill reported.
This contradicts a large body of scientific research and 3M's own records — revealed during a lawsuit in Minnesota — which show that the company has been aware of the toxicity of fluorochemicals and potential health risk since 1950, according to the Star Tribune.
Michigan Rep. Dan Kildee said the denials were "ridiculous," and that the companies knew of the health risks or they "wouldn't have taken them off the market in the first place."
Chief operating and engineering officer at DuPont, Daryl Roberts, said that his company supports regulation of two of the 5,000 types of PFAS but will only clean up the chemicals at its current locations. DuPont made and used one of these types of PFAS called PFOA in its non-stick cookware until 2015, when that part of the business was spun off into its own company, Chemours. Chemours has since taken DuPont to court over responsibility for addressing contamination, The Guardian reported.
California Governor Gavin Newsom signed an executive order Wednesday that would ban the sale of new cars in California that run only on gasoline by the year 2035. The bid to reduce emissions and combat the climate crisis would make California the first state to ban the sale of new cars with internal combustion engines, according to POLITICO.

A "trash tsunami" has washed ashore on the beaches of Honduras, endangering both wildlife and the local economy.
More long-finned pilot whales were found stranded today on beaches in Tasmania, Australia. About 500 whales have become stranded, including at least 380 that have died, the AP reported. It is the largest mass stranding in Australia's recorded history.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.
Sweden is a world leader in renewable energy consumption. Swedish Institute/World Bank
Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
