For more than a quarter century GRU has disposed of processed sewage on land in Archer.

Now some neighbors want it to stop because they're afraid it's toxic, even though the Alachua County Health Department say the material isn't harmful.

Eight and a half tons of processed sewage are applied every day. GRU engineers say there are no significant risks and believe they're actually improving conditions at the farm.

"Bio solids are being used as a fertilizer at that farm, it is a practice that mutually beneficial to the farmer and us," says Rick Hutton with GRU.

"Class B sludge has never been proven to be 100% safe it is always an assumption or a consensus, we want scientific facts," says Victor Pissari, a resident of Archer.

County Environmental Officials are concerned that medications people take ends up in the sewage and therefore comes up in the Bio Solids.

The department is looking into it.
