There are few things plants like more than animal and human waste. I did an experiment in highschool about the filtering ability of native plant species. This was Florida in the mid-nineties. SE Water management district gave me a and a few biologists a 2 acre plot of land near the waste water processing plant and let me have at it. Using treated grey water, a bog was started at one end with rows and rows of sawgrass. The water that made it to the end was crystal clear. After the experiments were done and went off to college, to pursue CS of all things. The district sold the land to developers who built yet another unneeded warehouse/stripmall in South Florida. Later on the state and Fed went on to a billion dollar buying spree of tracts of land through the middle of the state. Those experiments are still continuing there 10 years after I published my results.
