Groundwater Protection in Selected Countries 2. Point Sources
In the USA, there are federal agency-based programs, state-based programs and voluntary clean-up programs for contaminated sites. In the following, the federal programs Superfund and RCRA are discussed. 2.1 Number of SitesListed sites Information regarding the number of sites listed in the above-mentioned federal programs is shown below:
Remedy completion In March 1999, construction of the remedy was completed at 599 of the Superfund NPL sites. At some of these sites, operation such as pump and treat or cap maintenance is continuing. (Means, 1999). Few RCRA sites have obtained "clean closure" requirements. 2.2 Time frame for clean-upSuperfund receives a budget annually and a specific time frame for the length of the program is not available. The current feeling is that a Superfund Program, possibly in a reduced form, will be necessary for many years to come (Means, 1999). Current estimates suggest roughly 40 new NPL site proposals each year. Since its focus is on proper management of wastes, the RCRA is considered an on-going program. 2.3 CostsSuperfund Funding of the Superfund program varies from year to year. In 1999, 1,0 billion USD were received to maintain central headquarters and 10 regional offices as well as site specific work such as:
About 70% of the clean-ups in the Superfund program are paid for by the responsible parties (polluters). Overall, 15,5 bill USD have been contributed to the program by polluters. This means that about 1,0 bill. USD pr. year is directed to the program in addition to the federal Superfund budget. Finally, approximately 0,5 bill. USD are appropriated for the following Superfund related activities:
RCRA Clean-up under the RCRA program is financed by the individual polluters. Specific data on costs were not obtained.
