Allen Hazen
Allen Hazen (August 28, 1869 – July 26, 1930) was an American civil engineer and an expert in hydraulics, flood control, water purification and sewage treatment.

APHA color
APHA color, also referred to as the Hazen scale, and more appropriately as the Platinum Cobalt(Pt/Co) scale, is a color standard named for the American Public Health Association and defined by ASTM D1209. Pt/Co scale and APHA color are color scales.

ASTM International
ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services.
See Pt/Co scale and ASTM International
Parts-per notation
In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction.
See Pt/Co scale and Parts-per notation
Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change.
West Conshohocken, Pennsylvania
West Conshohocken is a borough in Montgomery County, Pennsylvania, United States.
