Workshop teaches lead remediation

  // Sunday, 10 August 2014 21:34 //

Participants in a lead remediation workshop organized by Groundwork New Orleans got to observe soil analysis firsthand Sunday in the Earth Lab environmental classroom in a lot adjacent to the Healing Center on St. Claude Avenue.

The free workshop, “Living With Soil: Issues, Outcomes and Interventions in New Orleans,” was offered to homeowners, landlords, renters and urban gardeners concerned about lead contamination.

Dr. Howard Mielke, a research professor in Tulane Medical School’s department of pharmacology and a nationally recognized expert on soil analysis, pressed an X-ray fluorescent analyzer against various soil surfaces to get immediate readings.

The spectrometer is able to quantify the presence of any element from magnesium to uranium.

The findings — as low as 51 parts per million and as high as 228 parts in an area close to a recently renovated house — showed a decisive improvement over the lead levels measured during a 2001 mapping study in the Marigny and Bywater neighborhoods.
