The objective of this project is to test and evaluate rapid-cure, chromatefree, and low-volatile organic compound (VOC) solvent-based primers that meet the requirements for use on tactical Navy aircraft, such as the F/A-18 Hornet jet fighter, the AV-8 Harrier groundattack aircraft, the UH-1Y Venom utility helicopter and the AH-1Z Viper reconnaissance helicopter.
High Efficiency Media for Metals Removal in NPDES Discharges (Project 585)
This project team is evaluating the performance of one specific filtration media for removing metals from various discharges and sources, including stormwater runoff and other shipyard activities, to help maintain regulatory permit compliance. The team also aims to expedite field deployment of the media during the first year of the effort.
Real-time Multi-contaminant Detection System (RMDS) (Project 584)
This project is developing an integrative approach that will enable near real-time monitoring of constituents of concern at shipyard drydocks.
