Aerial photos taken on 5/11/2020 show wastewater on neighboring properties outside the Triple PG mine in Porter are higher than in the mine’s settling pond. If heavy rains materialize this weekend as predicted, that wastewater could be flushed downstream into the drinking water for 2 million people.
Mine Has History of Dumping and Pumping
Earlier this year, I photographed the mine pumping wastewater from its settling pond toward the neighboring properties. A TCEQ investigation confirmed that wastewater had exited the mine for the fourth time in a year. Investigators found that the wastewater had levels of suspended solids 676% higher than water from nearby White Oak Creek. But they also found that elevation differences had confined the wastewater and kept it from entering the wetlands near White Oak Creek.
Heavy Rains, Flash Flooding Could Flush Water Downstream
However, heavy rains predicted for later today and Saturday could change that. Jeff Lindner, Harris County Flood Control meteorologist says rainfall rates of 1-3 inches per hour will be possible and there is a slight (10-20%) risk of flash flooding, both days. Isolated totals could reach 6 inches on Saturday, he predicts.
How High Is Water On Neighboring Properties
So how high is the water outside the mine compared to inside?
In the photo below, note the two sets of arrows on either side of the road. The strip of trees under the upper right arrow does not belong to the mine. However, the land under the lower right arrow does belong to the mine. I included the second set of arrows because they are closer to the camera and that makes it easier to see the elevation difference in the water. Notice how much higher the water is on the right than on the left relative to the road.

Photo taken 5/11/2020.Looking east over flooded properties (inside tree-line) that neighbor mine.Photo taken 5/11/2020.Terms of a temporary injunction restrict the mine from using its dredge. So the mine has started dry (or semi-dry) excavation. That meant removing wastewater from this pit.Photo taken 5/11/2020.
On January 20, 2020, I photographed the mine pumping water out of its settling pond toward adjoining properties. See below. The pit above can be seen in the upper left of the photo below.
See the pipe cutting diagonally from the middle of the frame to the lower right. Also note, the pond in the upper left of this image corresponds to the pond in the foreground of the image below.Note water level on January 20, 2020By February 13, three weeks later, that pond was largely empty. It is common for mines to pump water from one pond to another.But illegal to pump water outside the mine.
Why Mines Should Not Flaunt Rules
If approaching storms flush sediment- and chloride-laden wastewater downstream, it will end up in the San Jacinto East Fork and Lake Houston, the source of drinking water for 2 million people.
This underscores the need for the state legislature to pass laws that move mines out of the floodway. The Triple PG mine actually sits at the confluence of two floodways. That makes it vulnerable and dangerous…especially when an operator apparently flaunts rules designed to protect the safety of the public.

Aerial photos taken Monday this week (5/11/2020) show that Perry Homes’ contractors appear to be partially blocking drainage that serves dozens of homes on the western side of Woodridge Village in Porter. With heavy rain expected this weekend, residents like Gretchen Dunlap Smith are nervous.
Homes Flooded Twice Last Year by Water that Could Not Get Out of Neighborhood
Many of those homes flooded twice last year, in May and September, just as homes in Elm Grove did.
Looking south toward Kingwood along the western edge of Woodridge Village in Montgomery County.
The issue with these homes, however, was that water could not get out of the neighborhood because of altered drainage.
Water drains to the east (left) into the drainage ditch along the perimeter of Woodridge, and then south toward the top of the photo to Taylor Gully.
This enlargement, cropped from the photo above, shows how the perimeter road is pushing into the drainage ditch for homes in the older Adams Oaks subdivision to the right.
Hovering over Flower Ridge in Porter and looking southeast. Note how workers have pushed past Perry’s own silt fence (upper right) that marked the old edge of the ditch and how dirt from construction is now collapsing into the ditch.
Jeff Lindner, Harris County meteorologist said this afternoon, “Expect a line or complex of slow-moving thunderstorms to move across SE TX Saturday starting out west in the morning and spreading across the area throughout the day. There will be a low severe threat with this activity, but the main threat will be heavy rainfall.
As of Thursday, NOAA and the National Weather Service predict heavy rains and possible flash flooding across all of SE Texas.
That gives contractors one day, Friday, to clean out that ditch to avoid another possible flood and more possible lawsuits.

Houston After Harvey: Stories from Inside the Hurricane is an encyclopedic, almost kaleidoscopic collection of interviews with flood victims about their Hurricane Harvey experiences. The new Amazon eBook by two Houston authors, Jacqueline Havelka and Jill Bullard Almaguer, has a “you are there” quality to it. The interviews fall into roughly three categories: before, during and after the storm.
WhataBurger in Kingwood’s new HEB shopping center during flooding from Hurricane Harvey.
Story of a Natural Disaster Told Through Victims’ Eyes
They recount the stories of people watching in terror as water crept inexorably toward their homes and businesses, praying it would not reach their front doors. They speak of the chaos of emergency evacuations, when people suddenly realized they had waited too long. And finally, they reveal the shock and sadness of returning to often uninsured homes and the struggle to repair them without the financial means to do so.
Floods like Harvey affect every nook and cranny of the community and local economy.
Entire Range of Human Emotions
Readers of this book will experience the entire range of the human emotions. Helplessness in the face of nature’s rage. Numbness in shelters. Kindness of strangers. Tears of loss. Rage at looters. Bewilderment when navigating the government bureaucracy. The struggle to return to normalcy. And more. Much more.
The book is not all seen through the eyes of flood victims. A narrative section for the statistically inclined puts Harvey in historical perspective. The storm dumped more rain on the continental US than any other storm in history. Including a whopping 4 feet on Houston, a metropolitan area of seven million people.
One of the untold stories of Harvey, until now, is how Houston, a sprawling metropolis of diverse interests, came together in one of its darkest moments.
Half the community needed help. And the other half gave it.
Parts of this book will make you smile. Parts will make you cry.
A Cautionary Tale for the World
If you read the book in one sitting, it feels like a time-lapse video, as if you’re reliving the whole Harvey experience in fast forward. It literally took me back to those terrible days in August and September of 2017.
You never forget an experience, such as Harvey. And you shouldn’t. Even if you want to. Harvey is a cautionary tale for the world about the need to prepare for flooding. Even if you think you live on high ground. Most of Harvey’s victims lived and worked outside of any recognized flood zone.
Recommended For…
I recommend this book to anyone who thinks s/he is immune to flooding. I also recommend it to Harvey victims who want to learn about others who shared their plight.
Many flood victims may also want to give the book to friends and family in other parts of the country. It will help them understand what it was really like to go through a major flood. And more importantly, what it takes to come out whole on the other side.
Ms. Havelka and Ms. Bullard have made a huge contribution to the understanding of America’s most common natural disaster – flooding.

On April 21st, 2020, I reported on a sand mine that was river mining in the San Jacinto West Fork without a permit. It’s unlikely that any penalties will result. In fact, three weeks later, neither the Texas Commission on Environmental Quality (TCEQ), nor Texas Parks and Wildlife Division (TPWD), have even investigated the incident. State Representative Dan Huberty is calling on the heads of both agencies to understand why.
No Investigation by TCEQ or TPWD
The operation is called the Spring Wet Sand and Gravel Plant. Multisource Sand and Gravel Co., LTD, based in San Antonio, operates the plant.
I filed a complaint with the TCEQ on April 21. TCEQ referred it to the TPWD for investigation because TPWD regulates sand mining in rivers. Yet Parks and Wildlife did not even investigate the incident.
A TPWD game warden in Montgomery County said, “We need to catch them in the act. And even if we do, the fine is like getting a speeding ticket – inconsequential. It’s only about $500 per dump truck. At this point there’s no way to prove how much sand they removed. A better solution would be to have TCEQ pull their permit. We see these kinds of things right before a mine goes out of business. They just go out there and get the last sand they can get before they leave.”
Spring Wet Sand and Gravel may not have reached the end of operations yet, but pickings are getting slimmer as some of the photos below will show.
Scope of Mining More Apparent in May Photos
Compared to April 21 (when the SJRA was still releasing water from Lake Conroe), a recent flyover on May 11th revealed the full scope of the river mining.
Measurements in Google Earth show the point bar occupied about 7.5 acres. Assuming an average height of three feet, that area held more than 36,000 cubic yards of sand. That would equate to about 3,600 regular dump trucks (10 yards per average load).
At $500 per truckload, that totals $1.8 million. And that doesn’t even include the 8% tax that TPWD gave up on sales. But it’s not worth their time?
You have to catch a lot of hunters and fishermen without licenses to make up that kind of money. You would think it might be worthwhile for TPWD to investigate … even if it’s just half that much. That could probably pay the salaries of at least a dozen full-time employees.
Photo taken on May 11. Looking downstream outside the Spring Wet Sand and Gravel Plant, just south of SH 99.Closer shot reveals scrape marks from excavator are still visible. See lower right. Also note little pile of orange sand left behind.
The presence of the orange pile in the right foreground may provide a clue as to why the miners did not excavate lower in this location. Sometimes color continuity of sand from batch to batch is important. For instance, when making concrete blocks for a building, owners usually want the color of all the blocks to be uniform.

This may not be the end for this mine, but pickings appear to be getting slimmer.Spring Wet Sand and Gravel’s main processing facility
State Representative Huberty’s Response
Upon learning that TPWD chose not to investigate the river mining, State Representative Dan Huberty immediately contacted the directors of TPWD and the TCEQ to request explanations. Huberty has fought for a decade to regulate the industry in a way that protects both the public and law-abiding miners.
Dangers of River Mining
The type of river mining shown here is called “bar scalping” by scientists who study the impact of river mining. Some see bar scalping as the least destructive form of river mining. In general, though, most scientists still warn about dangers of river mining.
Increases in river bed and bank erosion both up- and downstream
Loss of agriculture land, houses and infrastructure
Failure of roads, dikes and bridges
Lowering of groundwater reserves
Reduction in water quality
Reduction in diversity and abundance of fish
Changes to riverside vegetation
For those reasons and more, river mining is prohibited in most countries of Europe. According to the World Wildlife Fund, “Europe has shown that developed economies can continue to prosper without resorting to river sand. Its supplies now come from crushed quarry rocks, recycled concrete and marine sand.”

On top of normal disaster preparation advice, FEMA and the CDC have released special instructions this year for hurricane preparation during the COVID pandemic.
Pet owners: Pre-identify shelters, a pet-friendly hotel, or an out-of-town friend or relative where you can take your pets in an evacuation. Local animal shelters may be able to offer advice on what to do with your pets if you are asked to evacuate your home.
Find out if your local public shelter is open, in case you need to evacuate. Your shelter location may be different due to the COVID-19 pandemic.
In your go-kit, include items that can help protect you and others from COVID-19, such as hand sanitizer, or bar or liquid soap if not available, and two cloth face coverings for each person. Face covers should not be used by children under the age of 2. They also should not be used by people having trouble breathing, or who are unconscious, incapacitated, or unable to remove the mask without assistance.
Practice social distancing. Stay at least 6 feet (about 2 arms’ length) from other people outside of your household.
Avoid touching high-touch surfaces, such as handrails, as much as possible. If not possible, wash hands or use hand sanitizers containing 60% alcohol immediately after you touch these surfaces.
Keep your living area clean and disinfect frequently-touched items such as toys, cellphones, and other electronics.
If you feel sick when you arrive at the shelter or start to feel sick while sheltering, tell shelter staff immediately.
Make sure children aged 2 and older wear cloth face coverings. Face covers should not be used by children under the age of 2. They also should not be used by people having trouble breathing, or who are unconscious, incapacitated, or unable to remove the mask without assistance.
Be a good role model—if you wash your hands often, your children are more likely to do the same.
Watch your children to ensure they stay at least 6 feet away from anyone who is not in your household.
Watch your child for any signs of illness and tell shelter staff if your child may be ill.
For monitoring upstream flooding levels, I find these two sites extremely helpful.
USGS Water on the Go – Includes information from almost every gage in the country. Especially useful if traveling. The app finds your location and automatically links to the gages nearest you.
Harris County Flood Warning System – Includes gages from Harris and surrounding counties, inundation mapping, customized alerts, historical flood levels, and more. Very powerful.

Last year, overland sheet flow from Perry Homes’ Woodridge Village contributed to flooding hundreds of homes in Elm Grove and North Kingwood Forest twice. Construction slowed last fall, but has now turned into a beehive of activity. Just days before a deadline for a deal with the Harris County and the City of Houston to buy the property. Yesterday, dozens of pieces of heavy equipment swarmed over the northern section.
N3 is surprisingly far along, perhaps 30-50% complete
Contractors are filling in wetlands and bogs with dirt excavated from detention ponds
They are building a concrete pilot channel down the east/west portion of Taylor Gulley
And they appear to be blocking out some roads.
These construction crews appear to have completed more work in the last month than the original contractors did in the last year.
Purchase Deal Faces May 15 Deadline
Perry originally set a May 15 deadline for a City/County commitment to purchase the property. Perry said that if they didn’t receive a commitment by then, they would continue to develop the Woodridge Village property and to try to sell it on the private market.
When Harris County commissioners last met, they put two conditions on a purchase:
That the cash-poor City of Houston donate land worth $7 million (half the purchase price) to Harris County Flood Control District, to help defray the cost of other other flood-mitigation projects.
Sources close to the deal believe that if Perry Homes gets a firm commitment by the 15th, that will keep negotiations open.
However, the last City Council meeting before the deadline starts this afternoon (May 12). Donation of land to Harris County Flood Control is not on the agenda. Neither is an Atlas-14 resolution.
Harris County Commissioners Court publishesthe agenda this Friday for their Tuesday, May 19th meeting.
Pictures of Work in Progress as of 5/11/2020
Below are pictures of the Woodridge Village work in progress. All were taken on 5/11/2020. It certainly appears as though Perry Homes is hedging its bets in case the City and County don’t come through with an offer. For orientation purposes, the first image shows where detention ponds go.

After months of foot dragging, construction activity at Woodridge is now in high gear. Perry Homes says it expects to finish work on the detention ponds sometime this summer.
Sale or no sale, that’s good. Hurricane season is just a little more than two weeks away. These ponds won’t be fully functional by then, but every little bit helps.

More than a decade after one San Jacinto West Fork sand mine stopped mining, the abandoned mine is still:
Inundated by floods
Leaking silty water into the river from multiple locations
Littered with mining debris
Unrestored.
That Was The Good News
Worse, it has little hope of ever being restored. The West Fork has captured one of the mine’s main pits as predicted two years ago. Now, process wastewater leaks from an upstream mine into the abandoned mine, and from there, into the river.
TACA fondly says that mines CAN be repurposed into lakes that make recreational amenities for residential developments. That’s true. If miners cared. If someone was watching. And if we had regulations that forced reclamation.
Last week, I published a story about an abandoned Texas Concrete Plum Grove plant on the East Fork. Today, I focus on a West Fork mine that used to be operated by River Aggregates as the Porter Sand and Gravel Plant. See below.
Landsat image from 10/28/2017. Comparison of this satellite image and the one below, both from Google Earth, shows that the area inside the large red circle was a settling pond in danger of being captured by the river. And it was.See below.Google Earth image from 12/1/2019, thirteen months later. Mine is outlined in red. Circles represent breaches that I will discuss below.New development on right is Northpark Woods.
The mine in question lies between Sorters-McClellan Road and the West Fork, and just north of the Northpark drainage ditch. It sits immediately west of the new Northpark Woods subdivision. The last image in Google Earth that shows active mining was dated 2008.
Current Images Show Lasting Leaks
Looking southeast. Both ends of the main pond (adjacent to the Hallett mine) have sprouted leaks. This is on the northwest side of the mine.Photo taken 4/21/2019.Looking southwest. The Hallett Mine, above the mine in satellite photos above, is almost overflowing in this image taken on 4/21/2019. It sometimes does overflow. See below.Looking northeast. Top circle shows where the Hallett Mine sometimes leaks into the mine in question. Bottom circle shows where the second mine then leaks into the West Fork (in the right foreground).Photo taken 4/21/2019.At the other (southeastern) end of the same pond, river migration cut into the wall that separated the mine from the West Fork. The pond now constantly leaks into the West Fork.Photo taken 4/21/2019.Here’s how it looks from the reverse angle. Looking east toward Northpark Woods development in upper right next to Northpark Drainage Ditch Photo taken 4/21/2019.Compare this with the photo below.
River Migration Led to Transformation
On September 14, 2017, I photographed the same mine from the same angle. Here’s how it looked then. Note that a narrow strip of land only a few feet wide separated the mine from the river at that time.
As the images above show, sometime between 10/28/2017 and 12/1/2019, the West Fork migrated into the mine’s settling pond. The breach then allowed the mine’s wastewater and wastewater from surrounding ponds to drain into the West Fork.
In 2018, on the first anniversary of Hurricane Harvey, I discussed the mine above in a post about river migration. The post said, “At the current rate, without human intervention, river migration should capture the mine … in about three years.” It took less than that.
The abandoned mine will not be much of an amenity for buyers in Northpark Woods. The forests and wetlands that once made this area such an ecologically rich place to explore are gone forever. So are the deer and the fish.
But downstream residents have it worse. They receive all the sediment flowing out of such mines and clogging the river. They must spend hundreds of millions of dollars to restore conveyance of the river so their homes and businesses don’t flood.
There are two lessons to take away from this and other abandoned mines. We need legislation that mandates:
Greater setbacks from rivers for mines. Get them out of the meander belt.
Posting of performance bonds the guarantee reclamation before miners start mining.
Miners can and do sometimes simply ignore the promises they made to restore the land before they got their permit to start mining. When they do, they leave us with a barren moonscape. Littered with craters. And a lasting legacy of loss.

Aerial photos taken on April 21, 2020 show that Harris County Flood Control District (HCFCD) finished its Rogers Gully project in the Walden area of Lake Houston south of FM1960. However, a significant mouth bar remains in the portion of the ditch owned by the City of Houston.
Looking west from shoreline of Lake Houston. Harris County Flood Control excavated accumulated sediment earlier this year in the visible portions of Rogers Gully.Looking east from same position, shows work still remains in the City-owned portion of Rogers Gully.
Project Did Not Extend to Lake Houston
The channel repair project extended from Trophy Place to approximately 1,400 feet downstream. Matt Zeve, Deputy Executive Director of HCFCD, said “We had worked this location a year ago, and the sediment accumulated in this spot again very quickly, so we had to come back.”
However, he added, “We won’t be getting the mouth bar.” The mouth bar is yet another one of the jurisdictional issues that plague homeowners around Lake Houston. The map below shows the HCFCD right-of-way in yellow. City of Houston (COH) is the red (actually COH owns all of the lake area even though it doesn’t show up on the map).
HCFCD excavated the yellow portion of Rogers Gully.
Zeve also said, “The mouth bar will have to be handled by another dredging contract that will come after the COH executes the $30 million program.” The $30 million program refers to the Huberty Amendment to SB500 passed during the last legislature.
The April photo of the mouth bar above was taken after a large rain when the lake level was up slightly. When the level is down, here is what the problem looks like.
The Rogers Gully mouth bar still appears to have the potential to back water up and contribute to neighborhood flooding.

Bright blue/green pond in foreground is part of Triple PG’s wastewater pit.
Likely Cause is Chloride Buildup
What is it then? “When you wash sand and gravel,” he said, “you often get very blue water. Most times it is high in chlorides. The chlorides discourage bacterial growth, or for that matter any life. The water is just too salty.”
Sand going to a big “washing machine.” The wastewater is then channeled to……a pond where silt settles out of the chloride-laden wastewater.Over time, the chloride concentration builds up and causes water to change color.
“Once a mine’s ponds get super saturated, they are no use to miners. That’s because they can’t wash the sand and gravel clean any more and they have to get rid of the water.”
Water-quality expert
“If it’s not chloride free,” he continued, “they can’t sell the sand because the chlorides will attack steel, such as rebar and girders, used to reinforce concrete. They also have to wash the sand used for pipeline bedding. If it’s not chloride free, the chlorides will attack the steel in the pipe over time.”
A construction manager for a major Houston refinery confirmed that chloride pitting and chloride cracking are indeed major concerns for pipelines. Not even stainless steels are immune.
Another part of the main wastewater pond at Triple PG mine
Saltwater Once Covered Entire Area
Where did the chlorides come from? The water-quality expert said, “This was a marine environment at one time, covered by saltwater. Over time, evaporation concentrated the chlorides and they were trapped by a confining layer…probably clay. Now that they are mining and washing material, the chlorides are the only thing left,” he continued.
“We used to see mines create dikes that were designed to fail in the event of a flood or heavy rain. If the chloride concentration got too high before a rain event, they would simply pump the salty water over the dike at night. Then they would replace it with fresh water and start the washing process over again. Dilution is the solution to pollution.”
Rapidly Changing Color Could Reveal Unauthorized Discharge
“If you continue to monitor this mine and the color disappears overnight, it’s a problem,” said the water-quality expert. That’s what I used to see often. The pond would become saturated and no longer usable. Then they would flush it out and it was usable again.”
The Triple PG mine currently operates under a temporary injunction and heightened scrutiny.
A Travis County judge set the trial date for June 22, 2020.
Flimsy Fixes to Other Dikes Remain
While the mine waits for trial, it has sealed those two breaches. But other prior breaches sport flimsy fixes that could wash out in the next large rain and discharge this water into the surrounding creeks. The mine has also been photographed pumping wastewater onto neighboring properties.
On 12/3/2019, I photographed the mine discharging waste water from what is now the blue pond onto neighboring properties.Site of repeated breach into Caney Creek from Triple PG mine (background), photographed on March 3, 2020.Site of another repeated breach into Caney Creek (left)from Triple PG mine, also photographed on March 3, 2020.
Potential Trouble Regardless of Cause of Color Change
Whether the color is due to high chloride content or cyanobacteria, it still poses a threat to drinking water. Chlorides would still need to be filtered out of drinking water pulled from Lake Houston. Cyanobacteria are worse. They often create toxins.
A World Health Organization (WHO) book called “Toxic Cyanobacteria in Water: A guide to their public health consequences, monitoring and management” claims WHO has found no documented cases of human deaths due to cyanotoxins. However, there have found many documented cases of animal poisonings. The most likely result of human exposure: dermatitis, “swimmer’s itch,” and severe oral and gastrointestinal inflammation. They also say cyanotoxins promote tumors in mice.
The Triple PG mine underscores the danger of allowing sand mines to operate in floodways and flush their wastewater downstream into the drinking water of 2 million people.
I will continue to monitor the color of the water to see if it changes rapidly.

This is a rare, off-topic post. Flooding is one of the most heart-breaking things that families can experience. But this morning, I received two emails from my daughter-in-law, Dr. Aylin Ulku, that are even sadder. They describe health care delivery in the Four Corners area. The first email contained photos of doctors making rounds in a motel. The second was a link to a post by her colleagues called “I’m Sorry.” It describes the plight of a people and their caregivers in poetic terms. Make sure you read all the way to the end. Warning: Keep Kleenex handy.
Delivering Health Care in Motels from Sidewalk
Dr. Ulku is a professor of medicine at the University of California/San Francisco. She is currently helping to deliver COVID-care in Gallup, NM, as part of the University’s HEAL Initiative. If you’ve never been to Gallup, it borders the Navajo, Hopi and Zuni Nations.
She and her fellows currently work in four locations: Gallup; Fort Defiance, AZ; Chinle, AZ; and Shiprock, NM. In Gallup, which is the largest of those towns and on Interstate 40, she and her team are delivering heath care in motels.
She writes, “I attached a few photos of my colleague, Bassem (from UCSF) and Michelle (a Navajo nurse) as we make rounds on patients in the motels. We check in on their symptoms and about once a day transfer back to the ED (emergency department) as they get sicker. It’s amazing and complicated…an incredibly satisfying, but bizarre kind of community work.”
“This is the process in general: knock on door, find out how someone is doing, fill any meds needed and get them delivered, check oxygen, rarely examine fully with listening to lungs or examining wounds.”

Health care delivery from a backpack
Why the motels? It seems many unhoused, unsheltered folks have no other option. Many live in multi-generational homes and are afraid of exposing loved ones. Some are not sick enough to be in a hospital yet, but are still symptomatic. And some simply don’t have a way home.
“I’m Sorry”
Two of Dr. Ulku’s colleague’s wrote this incredibly powerful and moving story published in Medium. Samuel Percy, MD, is an anesthesiologist and Carlie Field, MD, is an obstetrician and gynecologist. They also currently work on Navajo Nation.

Dear beautiful girl,
I’m sorry. I’m sorry I was the first face you saw when you were born. I’m sorry I was the one to welcome you into the world wearing a white space helmet with a motor whirring to keep any trace of you from touching me. I’m sorry you only felt the semblance of human embrace through the double-layered dullness of my sterile gloved hands. I’m sorry we took you away from your mother. I’m sorry your head first lay on the firm bed of an incubator rather than your mother’s warm chest.
I’m sorry you heard the harsh beeps of our machines instead of the delicate coo of your mother’s voice singing the lullabies she learned from her grandmother. I’m sorry you spent your first seconds, minutes and hours down the hall from her with strangers robed in disposable, blue, plastic gowns. I’m sorry we were the first to bathe you, scrubbing away any remaining signs of the woman who brought you into this world. I’m sorry they told us it was to keep you safe.
I’m sorry. I’m sorry there wasn’t running water in your house so your grandmother couldn’t wash her hands. I’m sorry your lights flickered off when food was more important than gas to power the generator. I’m sorry we were culturally blind to how deeply togetherness and family are woven into the bedrock of your community making physical distancing illogical.
I’m sorry your mother couldn’t tell you the stories she learned from your cheii. I’m sorry the hospital was two hours away. I’m sorry the rutted, dirt road washed out when it rained. I’m sorry your resilient grandmother had to know so much suffering. I’m sorry there weren’t enough jobs where you live. I’m sorry your uncle had to work in the city. I’m sorry he had a cough.
I’m sorry. I’m sorry Dr. Li Wenliang’s warnings were forcibly silenced. I’m sorry we knew this was coming and chose to do nothing. I’m sorry we didn’t act fast enough. I’m sorry we ignored the recommendations of public health experts. I’m sorry we didn’t take this seriously. I’m sorry we didn’t have enough tests.
I’m sorry the President of the United States called it fake news. I’m sorry spring break on the beach was more important. I’m sorry this wasn’t just like the flu. I’m sorry there weren’t enough masks. I’m sorry we couldn’t flatten the curve. I’m sorry we were too late. I’m sorry that 100,000 deaths was a job well done.
I’m sorry. I’m sorry I was the last one to talk to your grandmother. I’m sorry the virus was so infectious. I’m sorry she had a fever on the day you were born. I’m sorry she couldn’t catch her breath. I’m sorry there was no effective treatment. I’m sorry I was so scared, yet she was so brave. I’m sorry I had to place a breathing tube. I’m sorry I pushed her onto the waters of the Lethe, but couldn’t guide her to the other shore.
I’m sorry there weren’t enough nurses. I’m sorry that it was too hard to prone her. I’m sorry she was alone when she died. I’m sorry she stepped out of the world just days after you stepped into it. I’m sorry she was just one of 1,864 deaths that day. I’m sorry they called me a “hero.”
I hope. I hope you never let us forget. I hope the schools reopen and you learn what we couldn’t. I hope the cafeteria is bustling with the laughter of children at lunchtime. I hope you get a chance to play basketball. I hope fans crowd in and cheer loudly for your games. I hope they drill you a well for your home. I hope there are more jobs when you grow up and you don’t have to choose between food and electricity.
I hope you have children and grandchildren. I hope you sing them lullabies. I hope you tell them we tried. I hope you tell them we could have done better. I hope you know you were the light that kept us going. I hope people tell you about your grandmother. I hope you know she was proud of you. I hope they tell you she cried when she heard you were born. I hope you know she loved you.
In solidarity,
Your doctors
COVID In the Navajo Nation
Navajo Nation is the largest Native American reservation in the United States with approximately 170,000 Navajo people living within its borders. As of this writing, there are 1,675 cases of COVID-19 in Navajo Nation making it one of the hardest-hit areas in the United States per capita and the numbers continue to rise. Teams are working hard to control the virus, but because of poorly funded health systems, long-standing structural violence, and the high prevalence of comorbidities that increase susceptibility to COVID-19, the disease’s spread is unrelenting.
