The United States biomedical R&D community faces limited treatment and disposal options for many of the mixed wastes generated by their research activities. These options are particularly limited for tritiated mixed waste that has both moderate to high tritium content and contains RCRA-regulated hazardous components. Lawrence Berkeley National Laboratory (Berkeley Lab or LBNL) believes it is es...

Software Testing via Coverage Analysis is the most used technique for software verification in industry, but, since manual generation is involved, remains one of the most expensive process of the software development. Many tools have been proposed for the automatic test generation: on one hand they reduce the cost of the testing generation process, on the other hand the quality of the test set ...

This paper focuses on the incremental impacts of coal ash and flue gas desulfurization (FGD) wastes associated with increased coal usage by utilities and industry under the National Energy Plan (NEP). In the paper, 1985 and 2000 are the assessment points using the baseline data taken from the Annual Environmental Analysis Report (AEAR, September 1977). In each EPA region, the potential mix of d...

23 years after the last original US HELP version 3.07, in 2020 Environmental Protection Agency released a new version, called 4. With this Excel-based model has arrived modern Windows world. However, itself remains 3.07. The papers deals with experiences of author using 4 and compares simulation results four versions (HELP 4.0.1, DOS 3.07 3.95 D included D) for two applications. First, RCRA exa...

Clearance of sludge has made a major task in latest periods. In the current study from KPRWTP were investigated concerning physicochemical characteristics & disposal options. Organic content petroleum clay soil was 0.23 ±0.09% and 0.186±0.1%, respectively. Metals average concentration: Chromium: 130.95±27.32 mg/kg Arsenic: 0.899±0.434 lead: 47.83±21.44 Cadmium: 18.33±9.04 Copper: 209Â...

The minimization of hazardous waste generation as well as the proper treatment and disposal of generated waste has great importance for the protection of present and future human health and the environment. The purpose of this study was to identify the extent of waste minimization practices carried out by Tennessee waste generators since September 1985, This was accompl i shed methodologically ...

The distribution of lead in soil samples collected from both surface (0 to 10 cm) and profile (0 0 to 10 cm, E 11 to 30 cm, Eb 31 to 50 crn, Bw 51 to 100 cm, and C 181 to 200 cm) at a 14-year-old rifle/pistol shooting range located in central Florida were determined using EPA Method 3051a (microwave, HNO/HCI=3:1, v/v). In addition to total lead analysis, Toxicity Characteristic Leaching Procedu...

Gasification technologies meeting the definition proposed by the GTC offer an alternative process for the recovery and recycling of low-value, secondary materials by producing a more valuable commodity – syngas. The multiple uses of syngas (power production, chemicals, methanol, etc.) and the availability of gas clean-up technologies common to the petroleum refining industry make gasification o...
