The researchers wanted to see if they could make wastewater safe for crop irrigation by using a slow sand filtration technique. They tested effluent from a sewage treatment plant and found that it didn't meet irrigation standards. But after filtering the water through different sizes of sand, the effluent improved and met the standards. This means that the combination of sewage treatment and sand filtration can make wastewater safe for watering crops.
