George Chandler Whipple (March 2, 1866 – November 27, 1924) was an American civil engineer and an expert in the field of sanitary microbiology.

It was the first text solely devoted to identifying and cataloging microscopic aquatic organisms that interfered with sources of drinking water.

"[15] Later in the 20th century, with a greater understanding by the engineering profession of the environmental impacts of combined sewer overflows, and the regulatory requirements for their control, the report would not receive the same plaudits today that it did in 1910.

While a partner at Hazen and Whipple, he was also consulting professor of water supply and sewage disposal at the Brooklyn Polytechnic Institute from 1907 to 1911.

As was common during this time period, no treatment (except for detention and sedimentation fostered by Boonton Reservoir) was provided to the water supply.

City officials were not pleased with the project as delivered by the private water company and filed a lawsuit in the Chancery Court of New Jersey.

[19][20] In the second trial, Whipple attacked the proposal by John L. Leal to treat the water from the reservoir with chloride of lime (calcium hypochlorite).

The chlorination system was declared a success by the Special Master, William J. Magie, and was judged capable of supplying Jersey City with water that was "pure and wholesome.

"[19][21] Despite his opposition to chlorination of the Jersey City water supply, Whipple recommended the addition of chloride of lime before the slow sand filters at Poughkeepsie, New York.

[19][22] Whipple's career took an important turn in 1911 when he was appointed Gordon McKay Professor of Sanitary Engineering at Harvard University where he remained until his death.

However, his extensive research and publications, his technical leadership and his position at the Brooklyn Polytechnic Institute prepared him for his new responsibilities.

[1] Along with his mentor, William T. Sedgwick, and Milton J. Rosenau, Whipple founded the School of Public Health in 1913 which was jointly supported by Harvard University and MIT.

Whipple, along with his colleagues C.-E. A. Winslow and Malcolm Pirnie, was part of a large group of people who traveled to Russia to during the time of the Kerensky government.

The institute, which was formed in 1913, promoted a number of useful public health measures including the development of uncontaminated water supplies.
