Del. Eleanor Holmes Norton (D-D.C.) is pushing Congress to pay for a new study of the health of residents of Spring Valley, where the Army Corps of Engineers is in the midst of a years-long effort to clean up buried World War I-era munitions.

Since munitions were first discovered in the Northwest D.C. neighborhood in 1993, federal officials have sought to reassure District residents that they were working to find and remove all of the leftover materials. A city-funded study in 2007 found the community’s health to be “very good” overall, but now the District is seeking to do a follow-up study.

The city has pledged $250,000 toward the study, and Norton is planning to offer an amendment to the Defense spending bill currently on the House floor that would add $1 million in federal funds for the report.

“I am committed to holding the Army Corps to its promise to remain at the site until all munitions are identified and removed or destroyed,” Norton said in a news release. “Thankfully, studies have shown that the overall community health status of Spring Valley is good, but we need to continue to monitor the health of residents who reside near the site.”

It’s not clear whether Norton’s amendment will actually come up for a vote. House rules prohibit members from inserting “earmarks” into bills that would benefit one particular community, though Norton has attempted to write her amendment in a way that evades that ban.
