Task 1: Reducing the Consumable Costs of Silica-based CMP
Develop and demonstrate technology for reducing the costs presently associated with implementing silica-based Chemical Mechanical Polishing (CMP) technology in silicon chip manufacturing.  Proposed solutions must not degrade CMP performance below that of present industry practices.

Task 2: Arsenic Treatment for Domestic Water Systems
Develop and demonstrate a cost-effective treatment technology (including materials and supplies, operations, maintenance, and waste disposition) to remove arsenic [As (III) and As (V)] from drinking water in small water delivery and domestic water systems.  Your proposed solution must also include a scale-up drawing and detailed cost analysis as well as the benefits when compared with other technologies.

Task 3: Perchlorate Treatment for Domestic Water Systems
Develop and demonstrate a cost-effective treatment technology (including materials and supplies, operations, maintenance, and waste disposition) to remove perchlorate from drinking water in small water delivery and domestic water systems.

Task 4: Carbon Sequestration
Develop new and innovative techniques for removal and permanent storage of carbon dioxide from the atmosphere.  Your proposed solution must address permanent storage of captured CO2; environmental impacts; as well as the total costs associated with the process.  The ideal solution will be able to achieve these objectives at a cost of $10 or less per metric ton of extracted carbon. 

Task 5: Reduction of Fecal Bacterial Load in Produce Packing House Wash Water
Develop and demonstrate a practical and cost effective method for redcucing or eliminating fecal bacterial load in post-harvest produce wash water.  The user is an individual packing-house that must prevent subsequent produce cross-contamination by tainted water.

HS Task: Perchlorate Treatment for Domestic Water Systems       
Develop and demonstrate a cost-effective treatment technology (including materials and supplies, operations, maintenance, and waste disposition) to remove perchlorate from drinking water in small water delivery and domestic water systems.
