Affected pipe rails have only been found in a few parks. A very small percentage of our railing is affected. Please link here to view the spreadsheet that we’ve used to track our work while measuring all of the pipe rail in our system. Parks highlighted yellow are what we call, P1 sites, or sites that are first on the list for remediation. These sites have exposure rates over 50 microroentgens per hour, the acceptable level of radiation according to the Louisiana Department of Environmental Quality.
