Sediment Inactivation Services

ERD is one of the pioneers in sediment inactivation projects within the U.S., with current personnel conducting sediment inactivation projects as early as 1982. ERD has conducted more than 26 sediment inactivation projects throughout Florida, with a combined total area of more than 5000 acres. ERD pioneered the concept of calculating required aluminum doses based upon available phosphorus within the sediments and has conducted extensive research into water column, ecological, and sediment impacts from alum addition. ERD has been involved, either in dose determination or actual application (or both), for virtually all applications conducted within Florida. During 1992, ERD developed a modified phosphorus speciation technique to identify available phosphorus in lake sediments which forms the basis for alum dose determination.
