Gopher Resource promised changes at Tampa's old lead factory. It kept polluting.

On the eastern edge of Tampa, smokestacks rise above Josefina Zepeda’s cozy bungalow. The stacks reach 130 feet into the sky, higher than anything else around them, and exhale plumes filled with toxic gases and metal.

They belong to the lead factory.

Zepeda and her 21-year-old son, Gustavo Araujo, have lived within 500 feet of the factory for more than a decade. They’ve felt its buzz day and night. They’ve seen smog fill the neighborhood, where cottages and industrial yards sit beneath a canopy of palms and oak trees dripping Spanish moss.

Zepeda sometimes develops a cough and stuffy nose when she breathes the foul air. Araujo’s asthma worsens, his throat becoming scratchy and his breathing labored.

“I worry for him,” his mother said.

This past year, a Tampa Bay Times investigation revealed that Gopher Resource put hundreds of workers at risk by allowing toxic dust to accumulate inside the factory, prompting a $319,000 federal fine for workplace violations.

But the company’s practices have also threatened the surrounding community and environment, the Times has found.

Records show a pattern of the factory polluting the air and water that started in the 1960s and has continued since Gopher bought the plant 15 years ago.

To understand the plant’s environmental impact, reporters reviewed thousands of pages of regulatory and company documents, analyzed federal air emissions data and interviewed factory workers, neighboring residents and nearby business owners.

Among the findings:

Lead in the air


Gopher’s Tampa factory is the only lead smelter in Florida and one of only 10 such operations in the U.S.

Inside, workers take old car batteries, extract the lead and melt it in furnaces to make new blocks of metal to sell.

The process recently has been marketed as “green,” a way to save millions of lead-acid batteries from winding up in landfills each year. But the industry is an old and often dirty one. Across America, lead smelters have shuttered as they polluted communities and failed to adapt to tougher federal air-quality regulations that made it safer, but more costly, to operate.

This story is part of a collaboration with FRONTLINE, the PBS series, through its Local Journalism Initiative, which is funded by the John S. and James L. Knight Foundation and the Corporation for Public Broadcasting.

Gopher leaders would not agree to an interview for this story. The company issued a series of statements, saying it had invested $140 million on environmental and safety-related upgrades since buying the Tampa plant. Over the last three years, Gopher’s leaders have put a quarter of the operating budget toward those improvements, the company said.

Air quality around the plant has improved since 2013. That’s no accident. Gopher came to Tampa at a time when the federal government was cutting allowable levels of lead in the community air by 90 percent. The company promised to meet that standard while also growing and fueling the local economy.

But inside the plant, problems mounted.

The Times’ initial investigation found the factory’s ventilation system for years didn’t function correctly and the company disabled key features meant to capture fumes in the workspace. As a result, workers were exposed to air-lead levels hundreds of times the federal limit.

Lead’s effects on a community can be easy to miss and hard to quantify. The poison is often invisible, settling into soil or household dust. But it is potent. Decades of research has linked even low-level lead exposure to cognitive and behavioral problems in children.

The community surrounding Gopher is especially vulnerable. More than 800 people live nearby. Most are people of color. More than a quarter are experiencing poverty.

Dozens of soil samples taken by Times reporters showed lead concentrations higher than typical levels in Hillsborough County. The highest concentrations were closest to the plant. Two results, taken within 1,500 feet, were higher than what the federal government considers dangerous for kids.

Gopher’s footprint in the community has grown steadily over the years. The company has spent at least $10.5 million on more than a dozen nearby residential and industrial properties. It has leveled some, leaving the blocks around the factory a checkerboard of empty grass lots and houses. Residents describe the transformation with a certain eeriness. One by one, they said, the homes were gone.

For those who have stayed, including longtime resident Andy Klodakis, the concerns linger.

He put it simply: “That battery place scares me.”

The lead factory wasn’t always in this corner of Tampa.

Gulf Coast Lead, as it was once known, opened its first plant in Temple Terrace in 1953. The company closed the smelter after a decade and replaced it with a two-story brick apartment complex called Normandy Park. In the 1990s, the federal government found that children at the apartments were playing in soil filled with lead-tainted battery chips.

The soil has since been cleaned up. To this day, the apartment complex houses families. It is treated like a U.S. Environmental Protection Agency Superfund site — a designation for some of the most polluted places in the country that have been decontaminated but the government continues to monitor.

Gulf Coast restarted its lead operation in a new factory about eight miles south, near the bend in the Palm River and CSX rail yard. The neighborhood was home to both industry and single-family houses.

“It’s always been that way,” said Valerie Washington, a former longtime president of a local neighborhood association.

At the new location, Gulf Coast racked up violations for polluting.

The EPA sued the company in the ’80s for contaminating the soil and groundwater. It quickly settled. A decade later, regulators found high levels of lead in the soil at a neighboring mobile home park. Some children who lived there had elevated levels of metal in their blood. State health officials later flagged Gulf Coast as a significant source of lead exposure among children.

At the same time, the plant struggled to meet federal air-quality standards, regulatory documents show. Rail yard workers told the county that emissions burned their eyes and throats and made them sick. Neighbors complained of pungent odors.

Gopher, which had operated a smelter in Minnesota for decades, bought the plant in 2006. It vowed to be a new kind of owner.

Almost immediately, the company announced plans to enclose the furnace area. Its longer-term plan, it said, was to build an entirely new, fully enclosed plant. The old one was open-air and allowed toxic chemicals, including lead, to escape into the neighborhood.

In 2008, during the early phases of construction, county officials cited Gopher for failing to take precautions to control dust, releasing too much lead into the air and submitting inaccurate records.

The scrutiny increased in November 2010. Using data from the previous three years, the federal government deemed a milewide area encircling the plant one of 18 places in the United States out of compliance with new, tougher standards for lead in the air.

Gopher finished building the new plant in 2012. But that year, roughly a third of community air readings exceeded the federal government’s limit.

It was around that time the lead smelter earned a dubious distinction: The cumulative amount of lead it had released into the atmosphere since 2000 was more than any other public or private plant in Florida, according to self-reported data.

In 2013, it ran into trouble with emissions again: County regulators found Gopher had released excessive amounts of lead, sulfur dioxide and volatile organic compounds. Then, in 2014 and 2015, fires at the plant discharged more lead than allowed into the neighborhood.

Over seven years, the county had fined Gopher $192,964 for air pollution.

After a rocky start to Gopher’s time in Tampa, levels of the poison in the community’s air started to fall.

In a statement to the Times, Gopher noted that the amount of lead in the air around the plant is far below national limits set by the EPA.

“These testing results irrefutably show that any emissions that could be attributable to Gopher remain far below EPA standards,” the statement said.

A Times analysis of county data through last year found the emissions captured by air monitors were lowest in 2014 and 2015. And in September 2018, the area around Gopher was removed from the list of places that didn’t meet the federal government’s standards for lead in the air.

Much of the decline was because Gopher had enclosed the furnace and other areas of the plant.

But the county’s air monitoring system can also be gamed, government regulators acknowledged. The county monitors run on a set schedule, allowing companies to plan. And Gopher did just that, its workers said.

Internal calendars, documents and interviews with 33 current and former workers show that Gopher took extra steps to keep emissions lower on the days it knew regulators were watching.

The county Environmental Protection Commission operates three air-quality monitors outside of Gopher’s factory. One is in the CSX rail yard behind the plant. Another sits outside an empty business off East 14th Avenue, a few blocks north. The third is at Kenly Elementary.

The monitors look like birdhouses with pitched roofs. As air flows through them, filters capture lead particles. Regulators swap out the filters, which are sent to a lab for testing.

All three monitors run on the same schedule: every six days for 24 hours, from midnight to midnight. The timetable is set by the county and published publicly by the federal government.

An area is deemed in violation of federal standards when a three-month rolling average of readings exceeds 0.15 micrograms of lead per cubic meter of air. Regulators then try to identify what caused the deterioration in air quality, and companies can be cited for actions that resulted in increased emissions.

What the government monitors recorded


At Gopher, company leaders made sure employees knew when the government monitors would be on, the employees said. They marked monitoring days on internal calendars at least as early as 2009. They sent emails about the monitoring, posted reminders on an internal television screen and referenced the schedule in a draft copy of a training manual.

“Everybody knew air monitoring day, when it was and what was supposed to happen,” said Ko Brown, a former furnace supervisor who left the plant in 2017 and is now suing Gopher, alleging that he unknowingly carried lead home from the factory and exposed his young son.

Workers, he added, were supposed to pay “special, special attention” to air emissions on those days.

Brown and eight other current and former workers said that entailed closing the plant’s doors and keeping heavy equipment inside. Four workers recalled colleagues being reprimanded for taking dirty loader trucks outside when the monitors were running.

Brown and another former furnace supervisor, Cliff Burnett, said the company sometimes slowed production on monitoring days. On top of that, the company activated machines that shot water along its fence line. Gopher told regulators the devices, known as water mist cannons, were used to control dust during construction in 2015. But eight workers told the Times the company mostly used them to keep the toxic dust from reaching the monitors when the three devices were collecting air samples.

“Basically, you’re playing God with the monitors,” Brown said.

It’s unclear how much of the improvement in air-quality readings can be attributed to the company’s practices on air monitoring days, or how well the data reflect emissions when the monitors aren’t running.

Three air pollution experts told the Times that Gopher’s actions would likely impact the air readings by driving down “fugitive emissions,” the industry’s term for dust or fumes that escape outside of the smokestacks.

Perry Gottesfeld, a lead expert who’s visited smelters around the world as executive director of the nonprofit Occupational Knowledge International, likened the actions to “cooking the books.”

In general, if a company intended to interfere with government monitoring or deceive regulators, that could lead to violations of the Clean Air Act, said Craig Benedict, a former longtime federal prosecutor who specialized in environmental cases.

Companies repeatedly caught taking such steps to hide pollution have faced criminal prosecution, Benedict said.

Gopher, which has not been charged with any crime, did not answer specific questions about its practices on monitoring days. In a statement, the company said it follows all federal and state regulations.

“We are fully cooperative, transparent, and act with integrity in all our dealings with regulatory agencies,” the company said. “Any suggestion to the contrary is patently false.”

The experts also criticized regulators for having a monitoring system that could be so easily predicted.

“They should do random monitoring,” said William Landing, an environmental chemist at Florida State University. “If you really cared about the impact this plant was having on the community, then that's what you would do.”

Sterlin Woodard, who served as the county’s air division director until taking a new position within the agency last month, said the six-day schedule is based on guidance from the EPA. He acknowledged wondering before whether it could be manipulated.

“I’ve got concerns about it,” he said.

He said he was unaware of Gopher altering its practices on monitoring days. As reporters described details, however, Woodard said he wasn’t surprised.

“I figured they had something like that,” he said. “They know the rules; they know the standards.”

Later, Woodard said the Times' reporting had prompted the county to probe Gopher’s practices. The county is now considering random monitoring, he said.

As Gopher worked to control air emissions, other environmental problems surfaced.

In February 2015, one of Gopher’s cannons shot water onto the property of a neighboring business, leaving the owner with burning skin, according to records. County officials sampled a substance left from the water on the ground and found high levels of lead, as well as cadmium and arsenic.

Gopher said a valve had malfunctioned, causing contaminated water to back up and flood into a water tank used for the cannons. The company added an alarm so the same thing wouldn’t happen again.

At the same time, Gopher was dealing with a separate water pollution issue.

Each year, the factory is allowed to release hundreds of pounds of lead and other contaminants into the city’s sewer system. But Tampa limits the levels of certain chemicals Gopher can discharge. One of them is selenium, a naturally occurring mineral that can be toxic in large amounts to humans and animals.

From July 2014 to March 2015, Gopher far exceeded the discharge limits for selenium into the wastewater. That was problematic because the city removes solid materials from the water and treats them. A contractor takes the so-called sludge cake to farmers for their soil.

When the selenium spiked, Tampa’s sludge cake was being hauled to cattle ranches outside Orlando. The city became aware of the problem in September 2014 and stopped deliveries to the ranches the following month. Officials traced the increase back to Gopher, which acknowledged having trouble controlling the mineral. In 2015, Tampa charged Gopher $180,892 for costs the city incurred by having to run additional tests on the sludge cake and dump it in a landfill, instead of sending it to the ranches.

Gopher’s problems with dirty water continued.

The state later determined Gopher had dumped contaminated stormwater into a drainage system that feeds into the Palm River and ultimately to Tampa Bay. In May 2016, Gopher entered into a consent agreement with the Florida Department of Environmental Protection that required the company to repair its systems, change its practices and pay $8,000 in fines.

But two years later, regulators found another issue: For months, Gopher had improperly rerouted dirty well water into the stormwater tank.

Gopher made the required stormwater upgrades, which included building a new 2 million-gallon tank. The state closed its case last year, after giving Gopher two extensions to complete work.

Other problems have emerged with the way the company handles its waste, including a byproduct of smelting lead called slag.

Slag, which looks like lava and hardens into boulders, can be dumped in landfills. But slag that is determined to contain high levels of pollutants must be shipped to a special facility because the chemicals could leach into the groundwater. That’s a particular concern in Florida, where groundwater is the primary source of drinking water.

At least twice in 2018, Gopher sent tons of hazardous slag to the Cedar Trail Landfill in Bartow and had to dig it up, according to records.

Both loads tested too high for barium, Gopher’s lab tests showed. The toxic metal can cause vomiting, breathing difficulties and heart arrhythmias.

Then, in April 2020, Gopher discovered the top layer of a double liner beneath the building designed to contain dangerous chemicals was leaking, posing a threat to the soil and groundwater.

The company entered into a consent order with the Florida Department of Environmental Protection in January that required Gopher to find a permanent fix for the liner, send daily inspection data to the state and pay a $9,710 fine.

The repairs were completed this past summer. But in October, another leak was detected.

Much has changed about the neighborhood around the factory since Gopher came to town. What was once a small smelter has transformed into a sprawling 300,000-square-foot operation. The factory is now permitted to produce six times the amount of lead compared to 15 years ago, when Gopher purchased it.

Gone are the Willow Creek mobile homes, at least seven houses and a smattering of businesses. The land they once occupied has been largely cleaned up. It belongs to the smelter.

Gopher bought the Tampa smelter in 2006. In the decade and a half since the purchase, Gopher has bought and razed nearby tracts of land and also upgraded the facilities. Use the slider to see how the neighborhood has changed.

Gopher says the air quality is now 80 percent better than the EPA standards require.

But just as residents worried about contamination decades ago, they worry today.

Clarenine Williams has lived in a shotgun house within two blocks of the plant for 27 years. She said she’s still alarmed by what she sees. She recalled spotting a “pale, vomit-green” cloud over the factory and watching a big fire several years back. Onlookers feared the plant would explode.

“That battery place has been a lot of problems for just about everybody,” she said.

Residents and business owners have reported concerns to the county about metallic smells, their fear of lead infiltrating well water, and mysterious wastewater floods in Gopher’s parking lot during the night.

Some complaints have been confirmed. Others were deemed inconclusive.

Sheris Mathews worked a few blocks away on East 14th Avenue. When she arrived at her business, Nighthawk Towing & Repossessions, one morning in December 2018, she found a waterline broken and a white substance covering the ground. It resembled “slushy snow,” according to records.

“It was all over my grass and all in the back of my property,” Mathews told the Times. “We didn’t know what it was.”

After Mathews walked through the slush, she said, her black sneakers turned an orange-brown color like they'd been bleached.

“That freaked me out,” she said.

The waterline break was the third on her property and spilled roughly 4,000 gallons of sewage. Because she shared a line with Gopher, the wastewater included the factory's discharges.

Records show Gopher's wastewater turns into a snowlike substance on the ground. It contains sulfates, which crystallize as the water evaporates. Unofficial lab tests taken by county regulators showed elevated levels of lead, copper, selenium and zinc in the slush.

The issue was fixed, Mathews said, and she’s had no other problems.

Other nearby residents have worried about the smell of drinking water. About factory alarms sounding and workers, outfitted in hard hats, lined up outside. About increased truck traffic, at all hours.

They described semitrucks overturning and getting stuck in ditches along the narrow roads.

Jose Vazquez, who has lived and worked in the community for seven years and is known for launching bids for political office, decided to have his blood-lead level tested after reading the Times' initial investigation.

His levels, he said, came back elevated.

Vazquez is not sure whether the plant played a role, but he plans to investigate further.

“I need to figure out why,” he said.

Meanwhile, two blocks down, the factory continues to hum, day and night, as dense clouds billow from its towering stacks.
