On November 8, 2018, the Power Line fell to dry grass at the foot of the Sierra Nevada Mountains north of Sacramento and called the most deadly fire in California’s history. Powerful winds swept the flames, killed 85 people, destroyed 18,000 structures, and damaged more than $ 16 billion through the Paradise in the Tinder Dry Forest.

Among the victims of fire was the city’s water system, which was addicted to toxins of smoke. Kevin Philips, a former town manager and a district manager of the Paradise irrigation district, said, “It is open to the atmosphere every time a family is burned. “Water is erupting [of lines that supply homes] Top speed and after all [the system] suppression. It creates a vacuum effect and comes back to smoke again with the system. ” Burning trees, plastics (plastic and other materials, including PVC water pipes, include benzene and other carcinogens. One year after the fire, the test result was 80 times higher than the legal limit of some drinking water samples.

The road that returns to a healthy water supply is longer, and you need to flush and test the system and replace the pipes. But after seven years of labor and $ 40 million in August this year, the new water system of the city will be completed and all toxic substances will be flushed.

Ashville’s flood was washed off the large water pipe and damaged 25 feet underground backup pipes.

From fires to floods, droughts, extreme heat and sea levels, climate change is getting bigger and seriously damaging the supply of drinking water around the world. Change has already been stressed or broken, the most hit with a water system. And as such climate impacts worsens, if expensive modifications exist, they are forced to modify expensive.

Alexandra Campbell Ferrari of the Water Security and Cooperation Center said, “Climate change is a great influence on the availability of water resources in terms of quality and quantity of water resources. “We are not actually dealing with challenges. Ultimately, we will not be ready to solve the floods, droughts and contamination that we will continue to face. ”


More than half of the US population is captured and filtered by forests. However, as the wild fire increases, the supply of indicators in the basin is gradually contaminated with excessive nutrients, including carbon, heavy metals and nitrogen and phosphorus dissolved due to burned wood and other forest materials. When a fire occurs, the house and village, plastic pipes and other humans ingredient Pollution water system. And after the fire, mud slides often occur to solve water quality problems by washing sediments, debris and other contaminants with surface water.

The floods are a big threat to the global drinking water system as the climate is warm and the atmosphere maintains more moisture. In September, Hurricane Helen swept the east coast of the United States and dropped a 14 -inch rain in Ashville, North Carolina for three days. For thousands of years, the flood has disappeared the housing, business and infrastructure of the mountain community, including the city’s water system.

flood Washed Large parasite pipes and damaged backup pipes that carry water from the treatment plant to the remaining systems are buried 25 feet underground. The 1,000 -mile small pipes in Ashville carried water to business and residence.

The debris was much more impressive because it occurred in a system built in 2004, which was designed more flexible as a result of the previous flood case. The officials said, “I thought they were doing their best as a means of the time.” Sayed that New York Times last year. “I don’t know how to build a system that can withstand a 1,000 -year flood, as I just experienced. If you have all the money in the world, you may probably do it. When you are a city with a budget of $ 250 million per year, you can’t do it. ”

“The wastewater system is not designed for this changing climate. They are designed for old climates that no longer exist. ”

In countries without water resources infrastructure, problems worsen. Recently, Pakistan, Niger and Chad Flood Sewer and President’s extreme flood incident. The pathogen was washed with drinking water, causing diarrhea and cholera. Floods contaminated in chari, which is already suffering from food crisis. Destroyed Food shops as well as crops in the field. In the southern Brazil, the spring flooded in the spring of 2024. Leptos pira In an urban environment with inappropriate sanitary systems.

High -intensity non -storms can wash toxic chemicals in downtown and reservoirs in the corrected fields, industrial sites and roads. Pollutants complicate the process of water therapy as the system overflow, the equipment is broken, the blockage is filtered, and more disinfectants are needed. As Asheville, many sewage and water treatment plants are built along rivers and lowland areas where floods are easy to occur, so climate change is expected to cause more damage to these facilities. These tasks increase the risk of contamination immediately and in the long run.

“The wastewater system is not designed for this changing climate.” Srbeda Charlam said. “They are designed for old climates that no longer exist.”

no way "Boil the water" Hurricane Helen was flooded at the local water treatment plant in October and then consulted in an old port in North Carolina.

Wells are also in danger. Hurricane Helen showed the test guy E. coli E. coli bacteria are polluted 40 % Private well on the path of Helen. Studies have shown that floods and heavy rains can cause other pollutants of human stool and leaked septic tank system. About 53 million people in the United States rely on individual wells, which are not regulated by the federal government and are not mandatory for pollutants.

Droughts made more frequent and intense by climate change can also affect water quality. When the water level is low, organic substances such as leaf breakdown and other vegetation are concentrated in the surface source, sprinkling the processing plant, which uses more disinfectants, that is, chlorine. However, organic substances can react with chlorine to create two toxic disinfected by -products (DBPs) -triahalose methane and halo acid. Utility is A Balance: Too small goats can lead to survival of an opportunity pathogen. Too many goats can accumulate harmful DBPs in drinking water. recent analyze Even at the level of restrictions on regulatory restrictions between the United States and the European Union, Trihalomethanes has found evidence that it increases the risk of bladder and colon rectal cancer for decades. Halo acetic acid is also considered a potential carcinogen.

In the Mozambique, drought lacked clean water, resulting in an increase in Sujin diseases such as cholera.

Rural areas, which lack advanced water treatment systems around the world, are also struggling. In Mozambique’s Nampula province, climate -related drought reduced rivers, shallow boreholes and wells. Clean water shortages have contributed to the rise of tropical diseases such as ohm, schizophrenia and lymph noodles. According to ~ In addition to vertical diseases such as doctors, cholera and diarrhea without borders. Solution: Selling a deeper and better cover.

Increasing frequency and strength due to fertilizers and contaminated excellence in extreme rainfall combined with warm water temperature. Harmful birds From freshwater. After a massive algae in the summer of 2014, Toledo residents in Ohio warned them not to drink tap water because they contained Siaoxin, which was produced with thick green birds of the farm. Exposure to naturally occurring compounds can cause serious diseases and even death by swimming or drinking in the affected water.

Experts say that the risk of bird flowers and the risk of drinking water are increasing. Sean Corson, director of the NOAA National Coastal Maritime Science Center, said, “Bloom started early.” Sayed Inside climate news. “They last longer. Their peaks are bigger. So some measures are worse. ”

Seawater threatens drinking water supply as the amount of river decreases. The Mississippi River has experienced droughts for the past two years due to lack of precipitation and excessive heat. The river figures threatened the seawater to move upstream from Mexico to contaminate the drinking water of New Orleans.

Mark “Hobbo” Cogne Beach (MARK “HobBo” Cognbi Beach, who solves water problems as a representative of the Plan Quamin Diocese at the entrance of Mississippi, said, “It was a very low river recently.” “Seawater is emerging. Last year, the parish authorities delivered bottled water to the residents, and the utility sometimes delivered a truck to the reverse osmotic filter or desalination device until the new factory of Belle Chasse could be completed.

California learned a difficult lesson on how to prepare in Paradise to cope with water risk of fire system.

Utility throughout the United States is studying various wires to adapt to changing water paintings. In Paradise, Philips said that the city learned a difficult lesson on how to prepare better. “We put the concrete meter box anywhere and the heat is more elastic.” “We no longer use a brass meter without plastic meters. And all houses are equipped with back flow devices, so if the house is burned, there will be no more chance of vacuum effect. ”

According to recent report The Pacific Institute and the Pacific Institute and Digdeep are the legal reforms in adaptation to the climate effect of the water system by Digdeep, which encourages clean initiatives in the marginalized community.

“Until our law reflects a kind of educational manual that we need to think about how to manage water resources, we protect the minimum stream flow and the level of pollution, reduce the amount of pollution in water, and set a fair approach to drinking water.” We will not achieve this goal. “
