ALL LANDFILL LINERS AND LEACHATE COLLECTION SYSTEMS WILL FAIL ...

"First, even the best liner and leachate collection system will ultimately fail due to natural deterioration, and recent improvements in MSWLF containment technologies suggest that releases may be delayed by many decades at some landfills. For this reason, the Agency is concerned that while corrective action may have already been triggered at many facilities, 30 years may be insufficient to detect releases at other landfills."

SUMMARY

The U.S. has 3,091 active landfills and over 10,000 old municipal landfills, according to the Environmental Protection Agency. However, in the "good old days," every town (and many businesses and factories) had its own dump. According to the 1997 U.S. Census, there are 39,044 general purpose local governments in the United States - 3,043 county governments and 36,001 subcounty general purpose governments (towns & townships). One suspects that there are many more old and abandoned commercial, private, and municipal dumps than the 10,000 estimated by the EPA.

Municipal landfills and their leachate (water) and air emissions are hazardous. Municipal landfills can accept hazardous waste under federal law. An unlimited number of 'conditionally exempt small generators' of hazardous waste have access to municipal landfills. (See 40 CFR 261.5).

All landfills will eventually fail and leak leachate into ground and surface water. Plastics are not inert. State-of-the-art plastic (HDPE) landfill liners (1/10 inch or 100 mils thick) and plastic pipes allow chemicals and gases to pass through their membranes, become brittle, swell, and breakdown. 

"...82% of surveyed landfill cells had leaks while 41% had a leak area of more than 1 square feet," according to Leak Location Services, Inc. (LLSI) website (March 15, 2000).

According to Dr. Fred Lee, "detection in new landfills can be difficult since the only way to know this is detection in the monitoring wells. The likelihood of a monitoring well at a single or double lined landfill detecting an initial leak is very small." Monitoring wells should be located in areas most likely to detect contamination (i.e., testing the ground water after it has passed under the landfill.) See: Subchapter I: Solid Waste. Lined landfills leak in very narrow plumes, whereas old, unlined landfills will produce wide plumes of leachate. 

Old and new landfills are typically located next to large bodies of water (i.e., rivers, lakes, bays, etc), making leakage detection and remediation (clean-up) extremely difficult. This is due to the incursion of surface water in both instances. Federal and state governments have allowed landfill operators to locate landfills next to water bodies under the misguided principle: Detection by monitoring wells can also be very difficult at lined landfills. Lined landfills leak in very narrow plumes, whereas old, unlined landfills will produce wide plumes of leachate.

Ground water flows downstream, or toward nearby lakes and rivers. In some cases, monitoring wells have been located around landfills in areas least likely to detect leakage (i.e., upstream of the groundwater flow). This is in violation of federal law. See Code of Federal Regulations (CFR): Chapter I - Environmental Protection Agency, Subchapter I: Solid Waste / PART 258 (Updated 1997) - Criteria for Municipal Solid Waste Landfills (Adobe PDF). If a landfill is located next to a water body, then the monitoring wells should be located between the landfill and the water; or (if there is no space left), in the water. See: EPA's Ground Water Monitoring

All landfills could require remediation, but particularly landfills built in the last 60 years will require a thorough clean-up due to the disposal of highly toxic chemicals manufactured and sold since the 1940's. See:Remediation and Brownsfields

  • Mechanisms Of Leakage Through Synthetic Landfill Liner Materials Imperial College, Great Britain
  • RECYCLING LEACHATE BACK THROUGH A LANDFILL: Based on the available literature, pumping leachate back through a landfill causes increased decomposition, and it seems logical that it would also create a super toxic leachate. In addition, it would most likely accelerate the decomposition of the liner itself, thereby allowing leachate to contaminate ground water at an increased rate.

LANDFILL COVER: The EPA allows the use of toxic incinerator ash as daily landfill cover, instead of soil, as the public was originally told.

LANDFILL DETECTION: Old, grown-over landfills can be identified by using GRP (Ground Penetrating Radar) or by reviewing county or state aerial photographs that often go back to the 1960's.
