Pump and Treat (P&T) remediation is the primary technique used to contain and remove trichloroethylene (TCE) and its degradation products cis 1-2, dichloroethylene (cDCE) and vinyl chloride (VC) from groundwater at the Naval Air Warfare Center (NAWC), West Trenton, NJ. Three methods were used to determine the masses of TCE, cDCE, and VC removed from groundwater by the P&T system since it became fully operational in 1996. Method 1, is based on the flow volume and concentrations of TCE, cDCE, and VC in groundwater that entered the P&T building as influent. Method 2 is based on withdrawal volume from each active recovery well and the concentrations of TCE, cDCE, and VC in the water samples from each well. Method 3 compares the maximum monthly amount of TCE, cDCE, and VC from Method 1 and Method 2. The greater of the two values is selected to represent the masses of TCE, cDCE and VC removed from groundwater each month.

United States Secret Service Agents protected Springwood, the home of Franklin D. Roosevelt in Hyde Park, New York for the 12 years that he was President of the United States of America. Franklin D. Roosevelt was the 32nd President and the only president ever elected to 4 terms, which means he would hold that office for 16 years in a row. President Roosevelt died on April 12, 1945, at the beginning of his fourth term. His death ended the need for the Secret Service to keep the family home and lands safe for him. Their job at Springwood had started long before that, when he was elected as President for the first time in November 1932. Today you can explore what it was like to be one of President Roosevelt's Secret Service Agents working here at Springwood. As you visit the President's home, grounds, and different buildings, test yourself to see if you have what it takes to protect the President by finishing your chosen activities in this Training Manual.
