What is bioremediation? Bioremediation is defined as the act of adding or improving the availability of materials (e.g., nutrients, micro organisms, or oxygen) to contaminated environments to cause an acceleration of natural biodegradative processes.
What are petroleum hydrocarbons? Total petroleum hydrocarbons (TPH) are a term used to describe a large family of several hundred chemical compounds that originally come from crude oil. TPH is a mixture of chemicals, but they are all made mainly from hydrogen and carbon, called hydrocarbons.
