The Largest Landfill in California Is as Tall as a 50-Story Building

Buried under a massive mound of trash in Los Angeles County sits what was once the largest landfill in California – the Puente Hills Landfill. This gigantic garbage dump stood nearly 500 feet tall at its towering peak, almost as high as a 50-story skyscraper.

This man-made mountain of waste reveals some uncomfortable truths about our throwaway society. Let’s explore Puente Hills and other landfills in California and beyond. You may be shocked to learn what takes up space inside these mammoth trash heaps.

We’ll also discuss how landfills harm wildlife and the urgent need to rethink our disposable culture.

California’s Landfill Problem

With nearly 40 million people generating tons of garbage each year, the Golden State struggles with waste disposal. In 2020 alone, Californians threw out about 44 million tons of trash. All this waste has to go somewhere, so landfills are a fact of life in California.

You can find landfills scattered across the state, but some of the biggest include:

• Puente Hills Landfill in Los Angeles County – the massive dump we’ll focus on below
• Altamont Landfill in Alameda County near Livermore
• Desert View Landfill outside Palm Springs
• Forward Landfill near Stockton
• Simi Valley Landfill & Recycling Center north of Los Angeles
• Prima Deshecha Landfill in Orange County

California has enacted various recycling and composting programs to reduce waste. But traditional landfills still dominate garbage disposal in the state. With its huge population and consumption, managing trash is a constant battle in California.

Inside California’s Landfills – What’s Really in There?

When imagining materials inside a landfill, many people picture stinky food scraps, lawn clippings, and other decomposing wet waste. Surprisingly, the number one component of landfills today is simply paper waste.

Paper products occupy a massive amount of space in landfills, from discarded newspapers, magazines, and mail to food boxes and office documents. Experts estimate paper accounts for 26% of landfill waste.

Plastics are another huge category at around 12% of landfill volume. Other major components include metals, glass, food waste, and yard trimmings. Much of what ends up in landfills could have been recycled instead.

The Story of the Puente Hills Landfill

To understand the scale of California’s landfill issues, let’s examine the history of the Puente Hills Landfill in Los Angeles County.

The Puente Hills dump began operating in 1957 to serve the growing suburbs east of downtown L.A. By the 1970s; it had expanded into the largest landfill in America. At its peak, this trash mountain covered 760 acres and rose nearly 500 feet tall.

In perspective, Puente Hills was almost the same height as the Great Pyramid of Giza! This man-made mega dump was nearly as tall as a 50-story skyscraper.

Puente Hills gobbled up trash at an unbelievable rate – over 12,100 tons per day during its peak years. That’s equal to the weight of about 1,200 African elephants! At this insane pace, L.A. County was dumping a whole Disneyland Matterhorn rollercoaster ride every week.

After almost 60 years in operation, Puente Hills finally reached its permitted capacity and stopped accepting trash in 2013. By the time it closed, the landfill had held around 130 million tons of waste – equal to about 1 ton for every person in the U.S.

What is Puente Hills Landfill Like Now?

Though Puente Hills closed over a decade ago, the massive landfill site remains a towering “trash mountain.” Without new garbage being added, Puente Hills has begun gradually settling and shrinking in size. But at nearly 500 feet tall, this man-made mega dump won’t disappear anytime soon.

The closed landfill still requires extensive maintenance and monitoring. A complex system collects gas emissions and pumps out groundwater to manage contamination. Crews constantly maintain plastic liners and other landfill containment systems. Though no longer active, Puente Hills requires ongoing caretaking for decades.

This dormant garbage dump serves as a sobering reminder of how much waste we generate. Even a landfill at rest remains an imposing monument to our disposable culture.

America’s Three Biggest Landfill States

To manage all this waste, landfills exist across the United States. But which states have the most significant number of landfills?

The top three are:

• Texas – The Lone Star State tops the list with over 500 active municipal landfills – more than any other state. With its size and population approaching 30 million, Texas generates 35 million tons of trash annually. To handle this, Texas has dozens of massive landfills like the Austin Community Landfill and the Fort Worth Southeast Landfill.
• California – As discussed above, California has hundreds of landfills to meet the waste disposal needs of cities like Los Angeles and San Francisco. The Golden State comes in second for total landfills.
• Michigan – Home to around 300 active landfills, Michigan ranks third for the most landfills by state. Significant cities like Detroit and Grand Rapids contribute large volumes of trash requiring disposal. Some of Michigan’s most giant landfills include Pine Tree Acres Landfill and Autumn Hills Recycling and Disposal Facility.

With so much waste tossed in landfills, these states face major environmental challenges, which we’ll explore next.

The Environmental Impact of Landfills on Wildlife

While modern landfills have more environmental protections than in the past, they still pose contamination risks and harm local wildlife.

Toxins can leak from landfills into surrounding soil and groundwater. Nearby animals and plants suffer the effects of this pollution. Landfills also disrupt natural habitats, impacting wildlife behavior and ecosystems.

Birds, rodents, and insects frequently scavenge landfills for food, leading to disease transmission. Litter blowing from landfills can choke, poison, or injure animals who mistake it for food.

Machinery and truck traffic at landfills also threaten wildlife. Animals foraging at landfills risk being struck by vehicles or entangled in onsite equipment.

With wildlife and ecosystems already facing so many threats worldwide, landfill pollution imposes yet another impact. We urgently need to make landfills cleaner and safer for all living things affected by these waste sites.

The Health Risks of Landfills

In addition to harming wildlife, landfill pollution also poses health hazards for nearby human communities.

Toxins and contaminants can leak into groundwater, potentially polluting drinking water sources. Landfill gas emissions release carcinogens and other harmful compounds into the air. Unpleasant landfill odors also lower the quality of life.

Studies have linked living near landfills to an increased risk of certain cancers, birth defects, and respiratory illnesses. The health effects are especially concerning for vulnerable groups like children and the elderly.

While modern landfills aim to contain contamination, risks persist. More oversight and monitoring are needed to protect human health in landfill regions. Transitioning to safer waste solutions would be ideal.

Rethinking Our Throwaway Culture

One thing becomes clear when looking at massive landfills like Puente Hills- we produce too much garbage! The average American generates over 4 pounds of trash daily, much unnecessary waste.

We need to rethink our purchases and break our disposable habits. Choosing durable, long-lasting products reduces waste. Cutting down on excess packaging and plastic helps too.

Composting food and yard waste also make a big dent – organics are estimated to account for over 25% of what ends up in landfills. Building a reuse, recycling, and zero-waste lifestyle takes effort, but creating a sustainable future is needed.

Landfills like Puente Hills reveal our flawed relationship with “stuff” and consumption. Our planet can’t accommodate our level of waste forever. The time for change is now before it’s too late.
