Abnormally Dry Canada Taps U.S. Energy, Reversing Usual Flow

Abstract:
This year was the first year where the United States sent more electricity to Canada than we received; Canada’s large hydroelectric dams have not been generating much electricity. Additionally, there has been more demand for electricity everywhere. Large hydroelectric plants that have historically been stable sources of electricity are now struggling with low reservoirs. For example, in California, around Hoover Dam and recently in Canada. Climate change may alter weather patterns and adversely affect the operation of hydroelectricity plants. Hydroelectricity is actually the lowest priority for water usage when there are droughts and wildfires, making water power less dependable or efficient. At the moment, California has a surplus of energy, but there aren’t enough transmission lines to carry the power elsewhere.

Discussion:
This article discusses the imbalance of energy exchange between the United States and Canada, and the difficulties of adapting dams and hydroelectricity to climate change. I think it is especially important to note how increasing climate disasters caused by climate change are taking up more and more of our resources. We are already being forced to choose short-term mitigation over long-term protection tackling the root-causes of climate change. This proves some of the many pitfalls of hydroelectric power, and the need for even more alternatives and clean energy development.

California Water Board Adopts Direct Potable Reuse Regulations to Increase Water Supply

Epstein, B. H., Osias, D. L., & Cho, B. S. (2024, May 23). California Water Board adopts direct potable reuse regulations to increase water supply: 2024 Luenr update. California Water Board Adopts Direct Potable Reuse Regulations to Increase Water Supply. https://www.allenmatkins.com/real-ideas/luenr-update-2024-california-water-board-adopts-direct-potable-reuse-regulations-to-increase-water-supply.html

California Governor Gavin Newsom’s executive order has prompted the development of a Water Resilience Portfolio, setting ambitious goals for water recycling—specifically, recycling at least 800,000 acre-feet of water per year by 2030 and 1.8 million acre-feet by 2040. The State Water Resources Control Board approved new regulations in December 2023 to support direct potable reuse (DPR), a method that allows for the recycling of wastewater into safe drinking water either directly or via a raw water supply. This initiative aims to enhance California’s drought resilience and reduce wastewater discharge to rivers and oceans. Currently, recycled water meets nine percent of the state’s demand, but overcoming public skepticism and strict regulations remains a challenge. The regulations will need final approval from the Office of Administrative Law by Fall 2024.

This article highlights a significant step forward in California’s water management strategy, bringing in DPR as a proactive solution to the issues of water scarcity and climate change. It also raises a good point on the challenge of public perception, notably the “toilet-to-tap” stigma that leaves people wary of recycled water. However, with the advanced treatment technologies listed, it’s apparent that we are undergoing a critical shift towards more sustainable and reliable water practices. In this way, we are bolstering water supply resilience (therefore also bolstering drought resilience) as well as implementing novel wastewater treatment methods into the environmental management landscape.

Biden-Harris Administration delivers $179 million from investing in America agenda for Innovative Water Reuse and drought resilience projects

Biden-Harris Administration delivers $179 million from investing in America agenda for Innovative Water Reuse and drought resilience projects. U.S. Department of the Interior. (2024, May 28). https://www.doi.gov/pressreleases/biden-harris-administration-delivers-179-million-investing-america-agenda-innovative

President Biden’s Investing in America gave a $179 million investment to recycling water in the West, funding innovative water reuse projects across California and Utah. This funding supports the new Large-Scale Water Recycling Program, which aims to enhance drought resilience by converting unusable water sources into clean and reliable resources. Under this program, individual projects are expected to add over 182,000 acre-feet of new water supply every year, which is enough to meet the average annual needs of more than 470,000 people, and thus strengthening water management and security in the region.

Environmentally, transforming unusable water into reliable supplies is a crucial step towards addressing the growing challenges of drought and climate change. It will provide a stable and reliable source of water, therefore creating sustainability as well as drought resilience. Nonetheless, it’s impressive to see such a large investment put towards mitigating these environmental challenges, especially considering that the funding is coming from the federal government. Since it comes from the federal government rather than local/state governments, this investment reveals that environmental issues and their consequences are finally getting more and more recognition. Furthermore, I’m thrilled to see that we are getting federal funding for our long and pervasive California drought. Hopefully, we will be able to see the effects of this funding soon.

Companies aim to release more treated oilfield wastewater into rivers and streams

Pskowski, M., & Baddour, D. (2024, April 29). Companies aim to release more treated oilfield wastewater into rivers and streams. The Texas Tribune. https://www.texastribune.org/2024/04/29/texas-treated-produced-water-disposal-discharge-rivers/

If oilfield wastewater is treated and dispensed into the Pecos River in West Texas, the current sandy and dry river could flow once again. Historically, oil companies had disposed of their noxious water, a byproduct from undergrounding gas drilling, by injecting it underground. However, recent earthquakes have linked back to this practice, leading Texas regulators to explore new alternatives for their oil industry’s wastewater. One potential solution would be to treat the wastewater and feed it into the Pecos River, giving it 840,000 gallons per day of treated oilfield wastewater. However, environmental scientists and advocates are concerned about the pollutants—like radioactive material and PFAS—still present in the treated water, raising questions about its safety. As of now, there are still many guidelines and regulations that the companies will have to bypass in order to obtain a permit, but some are optimistic that these discharges could be beneficial to the Pecos River in the future

I think it’s interesting how wastewater could be treated to fix up an entire river. While the river won’t exactly be gushing with water from treated oilfield wastewater, it will certainly open up many large projects around the river that could potentially bring it up to that level. In doing so, West Texas could bring new ecosystems to their dry side of the country. However, the biggest constraint to this seemingly-utopian project is the presence of chemicals and pollutants contained in the wastewater. Even though it might be treated, the wastewater—tested again and again—has been shown to contain harmful chemicals that could be detrimental to the surrounding environment. This brings up the question of how treatable certain types of wastewater is, and what the next steps are to remove such harmful chemicals to render the water reusable once again.

Something’s poisoning America’s land. Farmers Fear “Forever” chemicals

Tabuchi, H. (2024, August 31). Something’s poisoning America’s land. Farmers Fear “Forever” chemicals. The New York Times. https://www.nytimes.com/2024/08/31/climate/pfas-fertilizer-sludge-farm.html

For decades, the federal government encouraged American farmers to use municipal sewage on their millions of acres of farmland, claiming that it was rich in nutrients and that it would help empty the landfills of sludge. However, conducted research found that this sludge had high concentrations of PFAS, a toxic “forever chemical” known for its longevity. These chemicals are now being detected at alarming levels on farmland, affecting both livestock and produce—in Maine, 68 farms were contaminated of the 100 tested. Farmers are now filing lawsuits against fertilizer companies and the U.S. Environmental Protection Agency for failing to regulate against PFAS, and some are now stopping production to avoid endangering the public.

Even if we believe that we are doing good by giving back to the environment, we shouldn’t be complacent and overlook potential issues within our solutions. This article highlights issues with a wastewater treatment action—specifically, using sludge as fertilizer—that instead led to devastating long-term consequences—both environmental and physiological. It emphasizes the need to constantly examine our own policies, dive into deeper scientific research, and also spread public awareness to prevent similar environmental catastrophes. We must be cautious about what we deem “sustainable” if we don’t fully understand the consequences on ecosystems and human welfare.

The Water Pollution Control Plant (WPCP) located in Sunnyvale, California treats wastewater for over 160,000 residents and businesses before discharging it into the San Francisco Bay. Since its establishment in 1956, the WPCP is continuously upgrading to conform to new regulatory changes, like the Clean Water Act. In 2013, a long-term five-phase project called the Sunnyvale Cleanwater Program commenced. The $1.3 billion project aims to transform the facility into an automated resource recovery center, involving upgrading primary treatment equipment, implementing flood protection, and planning for future population growth with intensified treatment processes.

I’m thrilled to see that such a significant development is taking place a mere 20-minute drive away, right in our own bay. This article highlights the efforts of environmental treatment facilities—specifically wastewater treatment facilities—to continuously adapt to new and developing changes and dispense clean and recycled resources back into the environment. These advancements reflect an ever-evolving understanding of environmental responsibility, showing that our standards are not just maintaining but steadily improving. This sets a positive precedent for the future of environmental conservation.

Ecuador hit by Nationwide Blackout

León Cabrera, J. M., & Glatsky, G. (2024, June 19). Ecuador hit by Nationwide Blackout.
The New York Times. https://www.nytimes.com/2024/06/19/world/americas/ecuador-nationwide-blackout.html

Abstract:
In June, Ecuador experienced an energy blackout. There had been many blackouts leading up to this, due to the lack of infrastructure and their dependence on imported energy. With help from China, Ecuador had been working on building a $2.25 billion hydroelectric power plant- but, there were many construction errors and legal issues, delaying the project. The President declared a national energy emergency, with cars, traffic lights, houses, and even the subway system failing.

Discussion:
The blackouts in Ecuador revealed how mismanagement and lack of infrastructure can contribute to a dangerous national crisis. However, this article is showing the potential disastrous effects that will continue to increase when energy projects are not prioritized, in combination with rising temperatures and droughts that have contributed to the droughts in Ecuador.

Recycled Water May Prove Crucial for Northern California amid Ongoing Droughts, Climate Change.

The KQED article talks about the division of water recycling plants specifically about The San Francisco Bay Area lagging far behind Southern California in water recycling, which could take decades to catch up, according to policy experts. The lower half of the state recycled 83% more water than the Bay Area last year. With two multi-year droughts in a decade and the pace of human-caused climate change accelerating, water agencies in the region are grappling with the need for more recycled water. California’s climate is expected to grow more arid, providing 10% less water statewide by 2040, and recycled water must be part of the state’s plan to adapt to drought. 

 

With the Bay Area seemingly never going to stop growing as tech only keeps revolutionizing and silicon valley brings in more jobs and families, the Bay will need to respond for an upcoming demand in resources. So, the development of more efficient and effective methods of treating wastewater is crucial in ensuring a sustainable future, as it helps to minimize environmental pollution and the spread of diseases. The use of AI and machine learning technologies in wastewater treatment is a very interesting concept and not only helps to automate the process but also improves the accuracy and speed of decision-making, reducing the potential for human error.

Sacramento Regionalsan Expands Water Recycling Capacity with New Facility.

RegionalSan is upgrading its wastewater processing facility in Elk Grove, California, which processes wastewater from customers in Sacramento and West Sacramento counties. In an interview, various details and specifics were revealed and the new facility, called EchoWater, will clean sewage to the extent that it can be used to water food crops and the water will be used all the way down to Folsom. When complete, EchoWater will be the second largest facility of its kind in the US  as it is 3000 acres. The $1.7 billion project will remove ammonia from wastewater, filter it to a high degree and transfer it to agriculture. The new plant will provide 130 million gallons of recycled water per day for use in parks, ballfields, and medians in Elk Grove. 

 

The article highlights some of the major challenges and opportunities in the field of wastewater treatment and I am encouraged by the advancements being made in the use of technology to improve the treatment process. The use of machine learning and other advanced technologies, as well as the increasing focus on sustainability, will likely result in more effective and efficient methods for treating wastewater in the future. It is also important to be concious of all of the land this facility is taking up, 3,000 acres is not naturally cleared out, so the envornomental effects are notable solely based off of land used. Although, this is definitely a scenario where pros and cons need to be considered and what outweighs which as the overall goal of the plant will put less stress on different aspects of the environment by recycling water, one of the main drought prevent mechanisms, so there will be less stress on the ​​aquifers.
