How will the project be monitored?
Once completed, the group must achieve five successful years of measurable nutrient reduction in the water during a seven-year window, and will maintain upkeep on the marsh's vegetation, Graham said. Then, the wetlands will be turned over to the District.
Water samplers have a clear-cut technique for measuring how much pollution is siphoned out of the water as it passes through aquatic plants, Graham said.
Nitrogen and phosphorus levels are measured before water enters into the wetlands. Then, after working its way across the fields, and phosphorus and nutrients attach to plants or deposit into the soil, another sample is taken on the opposite end.
