New regulations concerning air emissions from municipal landfills may require the installation of gas collection systems at landfills. As landfill gas (LFG) is collected, water and other vapors in the gas invariably condense as a liquid in the system or are purposely removed in the normal treatment of the gas. Production of condensate may be through natural or artificial cooling of the gas or through physical processes such as volume expansion. Condensate is composed principally of water and organic compounds. Often, the organic compounds are not soluble in water; and the condensate separates into a watery (aqueous) phase and a floating oil-like organic (hydrocarbon) phase. This organic fraction may comprise up to five percent of the liquid. The purpose of this paper is to review the regulatory requirements which apply to condensate management, to characterize LFG condensate, and to review options for proper management of condensate, given the regulatory requirements and condensate characteristics. Sources of information regarding condensate characteristics include published and unpublished data, and data from a limited sampling program at four municipal landfill sites. The limited sampling program was specifically conducted to determine whether either the aqueous or the hydrocarbon phase of LFG condensate exhibited a hazardous waste characteristic or contained hazardous substances.
