a long history of lead contamination in the soil. new orleans is no different... but now a new project underway in the city ... hopes to find the least expensive... and most effective way...to deal with that lead contamination. maya rodriguez has the story. it's a backyard experiment... with the potential to bring widespread change.) dr. andrew hunt, professor,
university of texas at arlington: "we have already amended the soil..." doctor andrew hunt is a professor with the
university of texas at arlington... behind an abandoned home on saint roch avenue...he and a team of u-n-o students and locals...are working on a way to fix soil... that's contaminated with lead. ben shirtcliff is a uno student with a background in landscape architecture ...) ben shirtcliff, uno urban studies graduate student: "as a landscape architect, in school, you're never really trained to think about what contaminants might be in the soil, as you're working on a project.") dr. andrew hunt, professor,
university of texas at arlington: "there's lots of lead in the soils here in new orleans. and that is a problem for young children." //) "it can affect neuronal development and impact their iq." the team is using different types of phosphate... and mixing it into the soil... to see it chemically bonds with the lead. one of the mixtures is called appetite two... made from ground up fish bones.) maya rodriguez, reporting: "if the phosphate bonding works... it would make the lead insoluble. meaning...even if the soil was ingested, the bonding would prevent the lead from entering the bloodstream." ) the environmental protection agency says ... there should be no more than 440 parts per million of lead in soil... where children might play... and no more than 1,200 parts per million anywhere else. but in the yard ... lead registered at 3000 parts per million ... nearly seven times higher than it should be for children.) earlier this year... the city had to shut down multiple playgrounds for remediation...after finding lead in the soil. those working on this experiment... hope their efforts will help develop a less expensive way to fix lead contaminated soil. mr... ch 4 ewn. the department of housing and urban development is funding the project... with a half-million dollars.the team will monitor several sites in new orleans... over the next year.
