Hanby colorimetric test method was discovered in 1986 by John Hanby for identifying the presence of hydrocarbons in soil or water. The Hanby method offers a revolutionary solution to obtaining on-site samples that potentially contain petroleum related substances. Field testing is inherently costly, time consuming and, quite often, unreliable. The Hanby method is designed to provide a precise color indication of the concentration of petroleum (gasoline, diesel, crude oil, etc) in field samples. This rapid, accurate method won immediate recognition by the United States Environmental Protection Agency, state regulatory agencies throughout the United States and various international regulatory agencies around the world. When John Hanby received his Patent for the Hanby method, Hanby Environmental Laboratory Procedures, Inc. was founded by Barbara Hanby, a 100% woman-owned corporation, to promote this method by licensing the rights to manufacture and market this new patent from the inventor, John Hanby. H.E.L.P., INC has now dissolved and become the newly restructured company, Hanby Environmental LLC. The company took on new partners in management and marketing, and has relocated the manufacturing and office facilities to be strategically located in Houston, in close proximity to much of the petroleum related activity in the United States. In addition to serving customers throughout the United States, the Company offers its full product line to customers throughout the world. " The U.S. EPA has been documenting our methodology as an assessment tool, remediation monitor and leak detector tool since our first EPA publication in 1990: 'Field Measurements -Dependable Data When You Need It'," says John Hanby.
