Guam - At the request of  Federal receiver GBB, District Court Judge Francis Tydingco-Gatewood has ordered Guam EPA to investigate a number of dump sites within a 3 mile radius of the Ordot Dump.

In a Special Report to the Court filed Thursday, the receiver cites "several dump sites" near the Ordot Dump, and one very large one. The exact number is not stated.


Its not clear whether any of these sites are properly permitted, but the receiver notes that none of them are lined and therefore a source of leachate, "all dump sites produce leachate," states the receiver's report and leachate is "one of the principal causes of pollution from the Ordot Dump and one of the primary reasons for the Consent Decree."

In its request for an inspection of these sites, GBB notes that the "identification of all sources of  leachate and other groundwater contamination is an important step" in the final closure of the Ordot dump which is slated to close August 31.


 


And the leachate from these other, unlined dumps, are a "potential problem for accurately understanding and mitigating the pollution coming from the Ordot Dump itself " and "potentially complicates the process for final closure of the Ordot Dump."

GBB requested, and the Judge agreed in an order issued Friday, to require Guam EPA to investigate all dump sites within a 3 mile radius of the Ordot Dump to determine:


1. The compliance of these dump sites with applicable Guam and federal laws and regulations;
2. The size and approximate leachate potential for each such dump site;
3. The party responsible for the site;
4. The potential of the dump site to complicate the closure of the Ordot Dump; and
5. The steps recommended or taken by GEPA to eliminate these dump sites as a source of contamination of the environment in the vicinity of the Ordot Dump.

Composition of leachates from actual hazardous waste sites (SuDoc EP 1.89/2:600/S 2-87/043)

Treatment of landfill leachate is a challenge specially to the developing countries in the process of protecting their environment due to unaffordability of the available technologies. This study, Advanced oxidation combined with Membrane Bio- reactor (MBR) is an effort to achieve better treatment technique. It focuses on reduced need for infrastructure and smaller foot print of treatment facility by using MBR technology to perform activated sludge process. The subsequent advanced oxidation by ozone facilitates further treatment. Leachate of average age was preteated and fed into a laboratory MBR treatment module. Pretreatment efficiency and the change of MBR efficiency by recirculating the ozonated effluent were studied.
