Quick question about a lake problem...?

Question

a lake nearby is suffering from eutrophication (the fertilizer is being deposited into the lake from a golf course surrounding it) what could the golf course do (use subsitute instead to the fertilizer maybe?) to prevent further problems or to fix what they have caused? any suggestions?

Answer 1

Cleanup measures have been mostly, but not completely, successful. Finnish phosphorus removal measures started in the mid-1970s and have targeted rivers and lakes polluted by industrial and municipal discharges. These efforts, which involved removal of phosphorus, have had a 90% removal efficiency.[20] Still, some targeted point sources did not show a decrease in runoff despite reduction efforts.

Minimizing nonpoint pollution: future work
Nonpoint pollution is the most difficult source of nutrients to manage. The literature suggests, though, that when these sources are controlled, eutrophication decreases. The following steps are recommended to minimize the amount of pollution that can enter aquatic ecosystems from ambiguous sources.

Riparian buffer zones
Studies show that intercepting non-point pollution between the source and the water is a successful mean of prevention (Carpenter et al., 1998). Riparian buffer zones,an interface between a flowing body of water and land, have been created near waterways in an attempt to filter pollutants; sediment and nutrients are deposited here instead of in water. Creating buffer zones near farms and roads is another possible way to prevent nutrients from traveling too far. Still, studies have shown[21] that the effects of atmospheric nitrogen pollution can reach far past the buffer zone. This suggests that the most effective means of prevention is from the primary source.

Answer 2

Eutrophication is a naturally occuring process wherein plant growth causes an imbalance in the ecological cycle and a water body becomes over fertilized by it's own detritus. Chemical fertilizer from the golf course will likely accelerate the process however, they can't "fix" it. I doubt that there is anything a golf course would be willing to do to prevent further problems, although mulching the grass clippings and not using high nitrogen fertilizers would help. Dredging is probably the only practical solution at this point.

Answer 3

bear in mind that it incredibly is calling with regards to the beginning up of the fifteenth 365 days, so it incredibly is one fee under you may assume. on the beginning up of the 1st 365 days, there is not any appreciation of the fee, so which you purely could do fourteen calculations - no longer fifteen.
