Londonderry Lithia was a brand of bottled lithia water sold in the northeastern United States during the late 19th and early 20th centuries.

[1] The source of the water was in Londonderry, New Hampshire, and the company headquarters of the Londonderry Lithia Spring Water Company was in Nashua, New Hampshire.

Used as a table water and in the treatment of kidney troubles.As a marketing promotion, Annie Kopchovsky, the first woman to bicycle around the world, changed her name in 1895 to Annie Londonderry and carried the company's placard on her journey.

[3] According to the company, the water had been analyzed by Prof. H. Halvorson and found to contain among various other minerals 8.620 grains of lithium bicarbonate per Imperial gallon.

[4] However, following the prohibition of adulterated and misbranded drugs, a government chemist determined that the water contained only a spectroscopic trace of lithium, less than 1/1200 grain per gallon, and that sodium chloride and sodium bicarbonate had been added to some samples.
