Maryland has enacted limits on how much PFAS can be present in sewage sludge spread as fertilizer on farm fields, and a new round of local reporting has surfaced a criticism that has followed the law since it passed. The threshold may sit above the level most treatment plants already produce.
Governor Wes Moore signed Senate Bill 719 and House Bill 925 on April 28. According to a summary from the law firm Beveridge and Diamond, the measures restrict or prohibit land application of sewage sludge containing specified concentrations of regulated PFAS, defined in the legislation as PFOA, PFOS or a mixture of the two.
