July 4, 1961: Revolutionary Pipe Joint Patent; 1832: Letter from Chester Averill about Cholera; 2013: Natural Immunity from Cholera

Fastite Joint

July 4, 1961:  On this date, Patent Number 2,991,092 was issued to Mr. J. W. MacKay of the American Cast Iron Pipe Company in Birmingham, Alabama, for the Fastite push-on-rubber gasket joint for iron pipe.  The Fastite gasket uses a dual-durometer gasket having a stiff rubber ring to hold the gasket in place against insertion loads and a softer, fatter section to provide the leak-free seal.  The push-on gasket soon supplanted the bolted mechanical joint for virtually all underground pipe-to-pipe connections and is part of ANSI/AWWA C111/A21.11, Rubber-Gasket Joints for Ductile-Iron Pressure Pipe and Fittings. In 2014, Mr. MacKay is alive and well at age 104. He was inducted into the state of Alabama Engineering Hall of Fame in 2011.

Bathing in the Ganges River

July 4, 2013:  In today’s New York Times (July 4, 2013), there was an extraordinary article that summarized recent research findings on human genetic adaptation to killer cholera. A few quotes give a summary of the findings:  “People living in the Ganges Delta, where cholera is an ancient, endemic and often lethal disease, have adapted genetically to the scourge through variations in about 300 genes, say researchers who have scanned their genomes for the fingerprints of evolution.

The researchers also found unexpected changes in genes that protect against arsenic, suggesting that arsenic exposure in Bangladesh is not just a modern problem associated with deep tube wells but may have ancient roots.

These instances of natural selection probably took place within the last 5,000 to 30,000 years, the researchers say, and show how evolution has continued to mold human populations through the relatively recent past…. People with blood group O are particularly susceptible to cholera, and indeed few Bengalis have blood group O. John Mekalanos, a cholera expert at the Harvard Medical School, said the new finding was one of several that ‘are starting to give a strong impression that the human genome has been dramatically shaped by responses to microorganisms.’”

December 8, 1888: Bartlett Water Scheme; 1920: Pollution of an Artesian Well

Map showing Bartlett Scheme to export Passaic River Water to New York City

December 8, 1888:  Engineering Newsarticle—Jersey City Board of Public Works Opposed to Scheme Proposed by John R. Bartlett. “Jersey City, N. J .—At a meeting of the Board of Public Works on Nov. 3, the water supply question was still further discussed, speeches being made in favor of and opposition to the award of a contract to the syndicate represented by JOHN R. BARTLETT. The Citizens Committee has adopted the following resolution: “Resolved, That we are unalterably opposed to Jersey City making any contract with any private water company for a supply of water In Jersey City, as such a contract might surrender our rights In the Passaic river, and place us under the worst of monopolies—a private water company. We are in favor of the reorganization of the State Board of Water Supply; that the control of the drinking water of the State be given to said Board, with a view that all the cities in the State of New Jersey may obtain in the future an abundant supply of good water….

The Bartlett water supply project was formally presented to the city of New York on Nov. 30. Briefly stated, this proposal to furnish 50 million gallons daily of water to lower New York, under a head of 300 ft., comes from a syndicate of corporations in New Jersey. The water is to be gathered from the 877 sq. miles of Passaic river water-shed, stored in a reservoir at the Great Notch near Paterson, N. J., and is to be led by pipes and tunnel under the Hudson river directly to lower New York. The advantages claimed are-abundant supply by gravity, constant fire-pressure, sales of water by the city for motive power, the saving of great mains from the Central Park Reservoir down town, and the preservation of the Croton supply for upper New York and the annexed districts. The syndicate promises a supply within 8 years from date of contract, and will charge the city $75 per million gallons, payable quarterly. The project is endorsed by responsible parties. In a later issue we will give the plan in fuller detail….

Jersey City’s new water supply is being discussed at “citizens’ meetings”, and the opportunity has not been lost by the chronic crank. The bone of contention is a proposition to furnish water, made by a private corporation, a part of the Bartlett syndicate. Last Monday’s meeting was marked by a free fight in an attempt to eject a party who interrupted the syndicate attorney and defied the presiding officer in this fight tables and chairs were smashed and the club of a policeman alone stopped the row. At a preceding meeting, threats were made of hanging to a lamp-post the promoters of a private contract. It is to be hoped, for the good name of the city, that these proceedings will be brought to an end by the more reputable and intelligent citizens calmly discussing what is really a great public need, and taking such .action as will improve the present supply, whether this improvement comes from works of their own building or from a private corporation.”

Commentary:  The water scheme to transfer water from the Passaic River watershed to New York City attracted tremendous support and violent opposition. Ultimately, the U.S. Supreme Court ruled against the interstate transport of water without the agreement of the state which is the source of supply.

December 8, 1920:Engineering and Contractingarticle. Pollution of Public Water Supply by Spring Freshet. “In the spring of 1920 the engineering division of the New York State Department of Health was called upon to investigate an epidemic of gastroenteritis, followed by an outbreak of typhoid fever in the city of Schenectady, N. Y., which occurred subsequently to the gross pollution of the public water supply of the city by the water of the Mohawk River. The results of the investigation were set forth by Mr. Theodore Horton, Chief Engineer of the New York State Department of Health, in his reports to the Department….

The matter was first brought to the attention of the Division of Sanitary Engineering on March 20, 1920, when information was received that on March 15 and a few days following, the number of cases of gastroenteric disturbances in the city had greatly increased above the number normally occurring; and that this increase had followed a noticeable turbidity in the water, which had been greatest on the night of March 13 and during March 14 and had gradually disappeared after the latter date….

On April 1 the onsets of eight cases occurred, and for the next week the number of onsets ranged from two to six, the number gradually decreasing. The last case was reported as occurring on the 19th. In all there were 53 cases, 3 of which terminated fatally. The majority of the cases occurred about two weeks after the pollution of the well by the contaminated water of the river.”

Bathing in the Ganges River

July 4, 2013: In today’s New York Times (July 4, 2013), there was an extraordinary article that summarized recent research findings on human genetic adaptation to killer cholera. A few quotes give a summary of the findings: “People living in the Ganges Delta, where cholera is an ancient, endemic and often lethal disease, have adapted genetically to the scourge through variations in about 300 genes, say researchers who have scanned their genomes for the fingerprints of evolution.

The researchers also found unexpected changes in genes that protect against arsenic, suggesting that arsenic exposure in Bangladesh is not just a modern problem associated with deep tube wells but may have ancient roots.

These instances of natural selection probably took place within the last 5,000 to 30,000 years, the researchers say, and show how evolution has continued to mold human populations through the relatively recent past…. People with blood group O are particularly susceptible to cholera, and indeed few Bengalis have blood group O.
