Embalmers Used to Pump Corpses Full of Arsenic. Now It Is Turning Up In Groundwater.
From the time of the Civil War to the first decade of the 20th century, arsenic was the main ingredient of embalming fluids in the United States. Arsenic does not degrade, ever, into harmless by-products, so the burial practices of the end of the 19th century and first years of the 20th have left us with significantenvironmental hazards.
To be clear, we aren’t talking about minute amounts of arsenic. Embalmers often had their own special fluid blend, but they usually used from as little as four ounces to as much as 12 pounds of arsenic per body.
As caskets downgrade, as they do eventually, the arsenic is picked up by water moving downward and washed into the soil or the groundwater.
Sinking Land Brings Calls for Pumping Alternative
by Neena Satija
Amid a persistent drought, a growing population and a dwindling supply of surface water, much of Texas is searching for underground water resources.
But a large swath of Texas — home to close to one-quarter of its population — is looking for water supplies anywhere but beneath its surface. A century of intense groundwater pumping in the fast-growing Houston metropolitan area has collapsed the layers of the Gulf Coast Aquifer, causing the land above to sink. The only solution is to stop pumping, a strategy that some areas are resisting.
The geological phenomenon, unique to this part of Texas because of the makeup of the aquifer’s clay layers, is known as subsidence. Areas in and around Houston have sunk as much as 10 feet in 100 years, causing neighborhoods to flood, cracking pavements and even moving geologic faults that could lead to infrastructure damage. “It’s an upfront and personal issue when you’re on the coast and you see land loss,” said Mike Turco, who heads the subsidence districts responsible for addressing the problem in Harris, Galveston and Fort Bend Counties. “You have oil barracks that are out in Galveston Bay now.”
Subsidence has long been a concern in Harris and Galveston Counties, which are nearer to the gulf and more prone to flooding. Spurred by state lawmakers in the 1970s, the counties have worked to reduce their groundwater dependency to 25 percent from more than 50 percent. That number will continue to fall as they increase their reliance on rivers like the Trinity and San Jacinto, as well as planned reservoirs.
Neighboring Fort Bend County, on the other hand, which still relies on the Gulf Coast Aquifer for 60 percent of its water, is farther inland, and the effects of subsidence can be less tangible.
“There are perception issues,” Mr. Turco said. Whether subsidence means anything to someone depends on where you’re standing, he said. “If you’re standing next to the river, it could be a big deal.”
In Fort Bend County, unlike Houston, “there isn’t a ship channel to walk to,” he said.
Now that the county is starting to grow, in part because of the expansion of nearby Houston, studies by the subsidence districts estimate that if nothing is done, parts of Fort Bend County will sink about five feet in the next four decades. The impact could be lessened to just two feet under recent regulations asking certain areas to convert 60 percent of their groundwater supplies by 2025. Not everyone agrees with the approach. Some towns dislike the rules that force them to find alternative water supplies, worried about the high cost of conversion and unsure whether their own land is actually sinking.
“Typically, subsidence is equated to growth,” said Terri Vela, the city manager for Richmond, which is about 30 miles west of Houston. “And Richmond proper has not seen that growth. I don’t even know that we have subsidence today in Richmond.”
Ms. Vela pointed out that subsidence in the county affected some areas more than others. For instance, the land has sunk nearly a foot in 15 years just a few miles to the east of Richmond, in booming Sugar Land. But in Richmond itself, the ground has lowered less than three inches — although the Fort Bend subsidence district warns that could change if its outlying areas continue to grow as they have in recent years.
Alternative supplies have been difficult to find, Ms. Vela said. About five years ago, Richmond and a neighboring town, Rosenberg, secured a long-term contract to take water from the Brazos River, with plans to build a water treatment plant. But then the area was hit by drought, and the river’s flows were at their lowest by 2009. the towns were then besieged with requests from industrial and other water users to buy the newly acquired water.
The overwhelming demand for Brazos River water led the towns to question whether it would really be available. “Is this a long-term, sustainable water source?” Ms. Vela said. “Everyone else has put their straws in before we’ve gotten to it.”
Recently a company called Electro Purification approached the towns with a different solution: The company would drill wells on the other side of the Fort Bend County line. In other words, they would continue pumping groundwater from the same clay-based aquifer but outside the jurisdiction of the subsidence districts.
The proposal drew public outrage, with residents submitting hundreds of public comments questioning its effect on water levels in the aquifer and on subsidence.
According to studies by the Fort Bend district, the wells could cause the ground to sink an additional two feet in some parts of the county and potentially cause sinking in nearby counties. But those numbers have been disputed.
“There is more data out there that hasn’t been evaluated,” said Mike Gershon, an Austin-based lawyer for Electro Purification. “At this point, no one has told us what they think subsidence is realistically going to be on their property and what that adverse impact is going to be.”
Mr. Gershon said the company was willing to change its proposal based on subsidence concerns. “We want to make sure that our scientists, and we think we have good scientists — that they’re getting it right,” he said.
The case has been referred to an administrative law judge, who will hear arguments next year on whether the wells should be allowed. In the meantime, the Fort Bend Subsidence District is weighing its options. While it cannot prevent the drilling of wells outside its borders, the district could refuse to accept Richmond and Rosenberg’s plan for finding alternative water supplies.
“Here we have a proposal to convert to something that’s not really an alternative water supply,” a lawyer who represents the district, Greg Ellis, said. “It’s the same aquifer. It’s just 15 miles west.”
While some areas of Fort Bend County are sure to see more subsidence than others, based on population density, everyone must pitch in to reduce the problem, Mr. Ellis said.
“I think it’s the standard — my car doesn’t cause all the traffic; it’s all the other cars that are causing the problem,” he said, characterizing the attitude of Richmond and Rosenberg. “And my car was here first. So all you other people should take care of the problem.”

Our Top Ten Products
by Gene Franks, Pure Water Products
At near the end of 2013, I took a look to see what our best selling products at Pure Water Products were for the year. Some were predictable, some were surprises, and all point to a moral. I’ll tell you what our top ten sellers were first:
1. UV102. Pura UV Lamp #20. The top-selling product on the list was no surprise. This has been our best selling single item for a number of years. When Pure Water Products started in 1986, it didn’t cross my mind that I was getting into the light bulb business. We sell lots of Pura #20 UV lamps because it is the standard lamp for all Pura plastic whole house UV units, we’ve been selling Pura units since the early 1990s and have lots of customers who need annual replacements, and we have have an all-Pura website (http://www.purauv.com) that is the uncontested best source for Pura plastic units, parts, and information.
2. FC001, MatriKX CTO Plus carbon block filter cartridge, 9.75″ X 2.5″ size. This has for years been our favorite and our best selling filter cartridge. It’s the standard cartridge for our Model 77 countertop filter as well as our Black and White series reverse osmosis units and undersink filters.
3. DC006. WellPro 220 volt control module. This is a best seller we aren’t proud of. It’s a control module for a dry pellet chlorinator. We sell a lot of these because we make them available and most websites don’t, but also because it’s a part that fails often and has to be replaced. This isn’t a big profit item because we also have to handle lots of warranty replacements. The module has an 18-month warranty and a habit of dying before the warranty expires.
4. FC403. MatriKX CTO carbon block cartridge, 4.5″ X 20″ size. We sell lots of these because they’re the standard cartridge in our “compact whole house filters” and because they’re a popular “after market” replacement in Pura Big Boy ultraviolet units.
5. RO001. This is a product we’re really proud of, our Black and White undersink reverse osmosis unit. We build these RO units ourselves and customize them at customers’ requests.
6. FC453. 5-Micron Wound String Sediment cartridge, 4.5 ” X 20″ size. Standard in our compact whole house sediment units as well as Pura Big Boy units. People with high sediment well water go through lots of sediment cartridges.
7. RO200. This is the countertop version of our Black and White reverse osmosis unit. Another product that we build ourselves and modify according to the customer’s request.
8. UV013. The Pura UVBB-3. Pura’s 15 gallon per minute “Big Boy” triple whole house unit, with UV lamp, a sediment filter, and a carbon block filter.
9. DC008. Chlorine Pellets for WellPro dry pellet chlorinators.
10. UV007. Pura UV20-3. Pura’s 10 gallon per minute whole house UV unit, with 2.5″ X 20″ carbon block and sediment filters.
And now for the moral. From a business perspective:
1. What sells best are things that wear out and have to be replaced. Filter cartridges, UV lamps, and chlorine pellets are all things that are used up and have to be replaced.
2. Bad products may be more profitable than good products. This is an unfortunate fact. We’ve all heard of planned obsolescence. I bought a Bose radio a dozen years ago and except for a few Radio Shack batteries for the remote control, I’ve never had any expense after the initial purchase. The purchase price seemed high for a radio, but it turned out to be a great bargain. Chlorinator modules, on the other hand, cost half as much as my Bose radio and often don’t last through the warranty period. The manufacturer keeps making bad ones because people keep buying them. It’s a proprietary product–no one else makes one that fits the chlorinator–so sales roll on.
My Bose Radio
We don’t like this system, but we all seem to be caught in it. And for General Electric one can see how it makes more sense to purchase very cheap offshore chlorinator modules than to make good ones (as they did a few years ago) that last and last and hardly every have to be replaced.
