A hyper-transmissible form of the coronavirus that causes covid-19 has been found in US sewer systems in California and Florida, confirming its widening presence in the US.
Buckets of dirty water drawn from sewer pipes near Los Angeles and outside Orlando starting in late January are among those in which genetic mutations shared by a so-called UK variant have been detected.
California is in the early stages of a severe multi-decadal drought, exacerbated by the climate crisis. As Dan Walters pointed out in his recent commentary, we must move quickly to prepare for water shortages and wildfires.
A potent strategy to improve the state’s water storage capacity involves an ancient technology so ubiquitous that it is often overlooked: soil. The urgency of California’s drought and wildfire risks require that we invest in soil health now.
The undersea power line would run south from San Luis Obispo County, hugging the California coast for 200 miles before making landfall in or near Los Angeles. It would be able to carry electricity from a fleet of offshore wind turbines, providing Southern California with clean power after sundown and helping to replace fossil-fueled generators.
Fewer planet-warming emissions, less risk of blackouts and no chance of igniting the wildfires sometimes sparked by traditional power lines: Those are the arguments for the $1.9-billion Pacific Transmission Expansion.
It was a harrowing vision of the vulnerability of aging California dams — crews laboring feverishly to sandbag and drain the lower San Fernando Reservoir, as billions of gallons of Los Angeles drinking water lapped at the edge of a crumbling, earthquake-damaged embankment that threatened catastrophe on the neighborhoods below. Although the 1971 San Fernando earthquake and the near failure of the Lower Van Norman Dam have given rise to construction improvements — the much newer Los Angeles Dam survived an equivalent shaking in the 1994 Northridge quake — the overwhelming majority of California dams are decades past their design life span.
A cyberattack on a Florida water treatment plant underscores the need for strong security protections at the municipal level, attorneys and industry professionals say.
A hacker gained access to an Oldsmar, Fla. city computer on Feb. 5 and changed the level of sodium hydroxide, also known as lye, local authorities said. It isn’t yet known whether the breach originated from the U.S. or from outside the country. The Federal Bureau of Investigation is working with local authorities.
In the five years since Colorado’s Water Plan took effect, the state has awarded nearly $500 million in loans and grants for water projects, cities have enacted strict drought plans, communities have written nearly two dozen locally based stream-restoration plans and crews have been hard at work on improving irrigation systems and wastewater treatment plants. But there are big challenges ahead — drought, population growth, accelerating climate change, budget cuts, wildfires and competing demands for water, among others.
A hacker’s botched attempt to poison the water supply of a small Florida city is raising alarms about just how vulnerable the nation’s water systems may be to attacks by more sophisticated intruders. Treatment plants are typically cash-strapped, and lack the cybersecurity depth of the power grid and nuclear plants.
When turbines at a natural gas power plant in California go offline, battery energy storage will be used as a ‘much cleaner alternative’ to diesel or other fossil fuels in getting them up and running again.
Siemens Energy has been awarded an engineering, procurement and construction (EPC) contract to deploy large batteries at Marsh Landing Generating Station owned by US infrastructure investor Clearway.
Bracing for potentially a second consecutive year of dry conditions, California water officials, farmers and researchers participating in an irrigation conference discussed recharging aquifers with stormwater and increased water efficiency among ways to diversify the state’s water supply. The 59th annual California Irrigation Institute conference was held virtually last week, in time for the year’s second manual snow survey by the California Department of Water Resources.
A hacker gained entry to the system controlling the water treatment plant of a Florida city of 15,000 and tried to taint the water supply with a caustic chemical, exposing a danger cybersecurity experts say has grown as systems become both more computerized and accessible via the internet.
