SOIL ATTENUATIVE CAPACITY AND TRANSPORT POTENTIAL OF SOLID WASTE LEACHATES Aaron A. Jennings, Research Assistant Franklin S. Tirsch, Research Assistant Donald Dean Adrian, Professor Department of Civil Engineering University of Massachusetts Amherst, Massachusetts 01003 INTRODUCTION The Resource Conservation and Recovery Act of 1976 (PL 94-580) was enacted to "promote the protection of health and the environment and to conserve valuable materials and energy resources". This legislation directed the Environmental Protection Agency to prepare criteria for the classification of solid waste disposal facilities. These criteria are destined to have a profound impact on the solid waste disposal industry. Under the criteria, disposal facilities will be classified as acceptable (posing no reasonable probability of adverse effects on health or the environment) or as unacceptable. New facilities not meeting these criteria will be prohibited, and existing facilities not in compliance must be upgraded or closed. Details of the criteria of classification have been the object of much deliberation and have not yet been finalized. They will, however, probably not diverge substantially from the "proposed criteria for classification" published in the Federal Register [ 1 ]. If the criteria are promulgated using the proposed language and intent, then prevention of groundwater contamination will become a priority challenge facing the solid waste disposal industry. The proposed criteria utilize the concept of "endangerment" for the protection of groundwater. "Endangerment" is defined as the introduction of any physical, chemical, biological, or radiological substance into groundwater in such a concentration that (a) makes it necessary for an existing groundwater user to increase treatment of the water, (b) makes it necessary for a future user of the groundwater to use more extensive treatment of the water than would otherwise have been necessary, or (c) otherwise makes the water unfit for human consumption. Solid waste leachates will not be allowed to endanger groundwater quality. For aquifers containing groundwater which is currently used or is designated for future use as a drinking water supply, or for aquifers containing less than 10,000 mg/1 total dissolved solids, a facility will have two options. All leachate produced must either be collected through the use of landfill liners and be treated, recirculated, or removed, or else leachate migration must be controlled by utilizing the site's natural hydrogeologic conditions and soil attenuation mechanisms. In addition, comprehensive groundwater monitoring, a prediction of leachate migration, and an acceptable contingency plan for corrective action will be required for as long as leachates enter the groundwater. Prior to the release of these proposed criteria many states have attempted to protect groundwaters by prescribing certain practices in the sanitary codes. Massachusetts and Rhode Island have required a minimum 4 foot depth of separation between the refuse 255
