Central Chemical Corp.

History of Central Chemical Corp.
In important ways, the circumstances surrounding Thomas’s entry into the fertilizer business were not propitious. First, Thomas began business near the end of a half-century-long relocation of the fertilizer industry’s center. Though fertilizer use continued to increase in the Mid-Atlantic states and elsewhere during the period from 1870 to 1920, the manufacture of fertilizer began to shift to the Southern states in the late nineteenth century. By 1902, Charleston had replaced Baltimore as the fertilizer capital of the country. The Mid-Atlantic states’ share of total fertilizer use decreased from 34% in 1880 to 14% in 1920. By contrast, in 1920 the South-Atlantic states used about 50% of all fertilizers consumed in the U.S. Thus, Hagerstown could no longer enjoy proximity to the major centers of fertilizer-material production, and, while previously situated between the two highest-fertilizer-use regions of the country, it now found itself on the northern edge of a region that now dwarfed all others.

Second, Thomas’s decision to continue in the practice (apparently favored by Hagerstown companies) of making fertilizer primarily from bone and organic materials came at the start of a rapid increase in the demand for mixed fertilizers, but also at the beginning of a precipitous decline in the use of bone and bone products as a source of phosphorous in fertilizers. With the growing use of potash and phosphate rock, consumption of mixed fertilizers grew from 46% of the total in 1880 to around 70% in 1920. During the period from 1890 to 1910, when Thomas was focusing on his presumably unmixed “dissolved bone” fertilizers, mixed fertilizers were capturing market share.

Furthermore, the period from 1880 to 1920 is also characterized by the decreasing use of organic materials in general. Though organic materials provided about 91% of the total nitrogen in 1900, by 1917 the total nitrogen contribution from organics had dropped to 46.5%. With regard to phosphates, bone meal, dissolved bones and boneblack, and phosphoro-guano use peaked in 1890, but their use dropped to a negligible amount by 1910 as the use of superphosphates from phosphate rock increased dramatically..

Third, even as Thomas had begun his business trading fertilizer for livestock from relatively distant places, the fertilizer industry was increasingly turning to local distribution. Though mid-nineteenth-century fertilizer plants typically were situated in East Coast harbor cities, twentieth-century plants were dispersed to be closer to areas of consumption.

Finally, even though the name “Thomas’ Dissolved Bone” suggests that Thomas produced his own superphosphates initially, the use of bone in the production of superphosphates was on its way out as described above. For all practical purposes, then, Thomas had set his business on the track of the second, smaller type of fertilizer company, which only mixed fertilizer and did not produce superphosphates. For the next 90 years, even when Central Chemical had affiliates across the nation, it would remain in this “smaller” category – relying on large suppliers for its materials. For reasons noted above, this was not a problem at the turn of the century vis-à-vis the larger companies. Starting in the 1890s, however, many agricultural societies began to advocate home mixing of fertilizer materials by farmers. Throughout the first half of the twentieth century, the fertilizer industry fought this effort successfully by insisting on the value of industrial mixing processes and the farmer’s comparative disadvantages in mixing.

Though in its early years, Central Chemical advertised itself as “Exporters – Manufacturers – Importers,” by the 1970s it had become little more than a middle-man between larger suppliers and farmers. It did not import its own materials, but purchased granulated materials from suppliers. There is no evidence that Central Chemical was exporting products out of the country anymore. And its manufacturing capacity consisted of mixing pre-processed granulated materials in various proportions. At this point, its consulting capacity became equally important to its factory processes.

Though Central Chemical and its subsidiaries were taking in a combined $25 million in sales by the late 1970s, an employee remembers that there was always a sense of trouble on the horizon. The vulnerability of a company that adds very little value to its product and relies entirely on contracts with larger suppliers requires no explanation. It appears that not long after Central Chemical became a bulk blender, its large suppliers began pushing their advantages. In the early 70s, Central Chemical’s supplier, Agrico Chemical Company, put pressure on Central Chemical to enter into a long-term contract. When Central Chemical refused, Agrico withheld di-ammonium phosphate and granular triple super phosphate at a time of national shortage in these materials. Central Chemical responded by filing an antitrust lawsuit against Agrico in federal court. For most of the next decade much of the time, resources, and energy of what was still a closely-held corporation would be consumed in this litigation. Ultimately the lawsuit proved unsuccessful.

All of this came at the same time that local, state, federal regulators were investigating the Hagerstown plant for its pesticide-disposal practices. In the 1970s the State of Maryland ordered two separate cleanups of the site; the EPA was just getting started.

Ultimately the push to eliminate the middle man that drove the switch to bulk blending began to turn on the blenders themselves. The larger companies and farmers wised up, and realized that they could both save money by dealing directly with each other. Farmers began buying direct-application materials from the same suppliers used by Central Chemical. By the early 1980s, Central Chemical’s network of fertilizer blenders had contracted substantially. Blending operations like those of the Hagerstown plant could no longer make the case for themselves. Crushed under the weight of increasingly serious environmental liability for its mid-century disposal practices, the Central Chemical Corporation contracted its operations substantially. The Hagerstown plant ceased operations in 1984 and the office headquarters moved from the old Thomas building to an office outside Hagerstown.

EPA website regarding ground water & Lindane By Tim Jordan


The OU-2 investigation to delineate contamination in the bedrock aquifer is ongoing. Groundwater at the Central Chemical Site (Site) is primarily contaminated with pesticides and volatile organic compounds (VOCs). The pesticide plumes, which are primarily composed of isomers of Lindane [also known as hexachlorohexane (HCH)] are much more extensive than the VOC plumes of benzene and chlorobenzene. The HCH pesticide plumes have migrated great distances from the Central Chemical Site in all directions. The lateral and vertical extents of groundwater contamination have not been completely delineated. Accordingly, the current OU-2 groundwater investigation includes five new on-Site wells and three new off-Site wells to investigate the lateral and vertical extent of contaminants. Some of these wells were drilled to depths up to 450 feet below grade. Preliminary results from the OU-2 investigation indicate that pesticide contamination is deeper and more widespread than previously thought.

I have listed below what dangers Lindane. By Margie

Lindane

Lindane is an antiquated and toxic pesticide that was once used extensively worldwide. Despite a recent global ban on its agricultural use, the pesticide, a potent neurotoxin, is still used in shampoos and lotions in the U.S. to control headlice and scabies. California banned these pharmaceutical uses in 2001, and similar legislation is moving forward in Michigan.
Today, metabolites of the DDT-era pesticide are routinely found in human bodies. Data from the Centers for Disease Control and Prevention reveal a lindane component, beta-HCH, in the blood of 62% of people tested. Infants are exposed through the placenta and breastmilk, and lindane residue contaminates common foods such as rice and potatoes.

Human Health Harms

Lindane's body burden is a significant concern given its effects on human health — especially the nervous system. Human exposure to lindane is linked to a number of health impacts:
  • Neurological Effects:  Humans exposed accidentally to high levels of lindane have experienced seizures, convulsions, vertigo, and abnormal EEG patterns (ATSDR).
  • Cancer: Lindane is associated with elevated risks of non Hodgkin's lymphoma, liver, and breast cancer (ATSDR). California's Proposition 65 lists lindane as a chemical known to cause cancer. 
  • Endocrine Disruption: Lindane has been reported to interfere the hormone levels of human males exposed to the insecticide (ATSDR). In labratory studies, lindane mimicks estrogen in female rats and mice (Beyond Pesticides Factsheet).
  • Reproductive Effects: Pregnant women who miscarried or had pre-term babies had higher levels of lindane as well as other organochlorine pesticides in their blood.  Lindane is also linked to reduced sperm counts, and decreased ovulation in animal studies (ATSDR).
  • Immunological Effects: Lindane is thought to impact the human immune system. Workers exposed to lindane experienced increased levels of antibodies in their blood (ATSDR).
  • Liver Toxicity:  Exposure to lindane is linked to increased levels of liver enzymes, increased liver weight and liver toxicity (ATSDR).

Environmental Contamination

Lindane is an organochlorine, a class of pesticides that are notorious for their toxicity, mobility, and persistence in the environment. The persistent chemical shows up more often than any other pesticide in the Arctic, contaminating traditional foods of indigenous communities in the region.

Lindane Alternatives

Alternatives are available and in use around the world for both agricultural and pharmaceutical uses of lindane. A 2009 report from the International POPs Elimination Network presents specific alternatives for common uses of lindane around the world.
Scientists report that lindane is currently among the least effective means to control lice and scabies. California's 2001 ban of lindane's pharmaceutical products has resulted in cleaner water and less risk to children from exposure to the chemical, with viable alternatives effectively controlling lice and scabies outbreaks, according to a recent article in Environmental Health Perspectives.
