Internal Phosphorus Loading in Spring Lake: Year 2
Get PDFExperimental and desktop studies were conducted during 2004 to better understand the factors affecting internal phosphorus (P) loading in Spring Lake, Michigan. A prior study in 2003 resulted in estimates that between 55 and 65% of the total phosphorus entering the water column of Spring Lake, on an annual basis, originated via internal loading from the sediments. The results from the current study indicated the following:
Phosphorus release rates were no different at alum concentrations of ≥ 15 mg alum/L compared to 24 mg/L. However, the higher alum concentration is likely to provide greater spatial coverage over the sediments in the lake, more protection from alum redistribution after sediment resuspension, and is still well below concentrations of environmental concern.
Resuspension events, which would cause the sediments to become mixed, substantially increase total phosphorus concentrations in the water column, even at high alum concentrations, although the total soluble phosphorus concentrations remain low in the water column provided alum is present.
Bioturbation has the potential to increase phosphorus release into the water column. However, several lines of evidence in our data suggest that this process does not play a significant role in Spring Lake sediments. Desktop analyses focusing on lake morphometry revealed that Spring Lake is very susceptible to internal loading but not very susceptible to resuspension events. In addition, calculations indicated that given the current concentration of P in the sediment, internal P loading can continue in Spring Lake for another 40 years, even if all new sources of phosphorus are eliminated.
Taken together, these results indicate that an alum application of 25 mg aluminum/L is likely to result in a substantial reduction in the phosphorus concentration in the water column of Spring Lake. The length of treatment effectiveness will depend on the degree to which 1) the alum remains in place on the sediment-water interface and 2) current and future external phosphorus loading to Spring Lake is reduced

Internal Phosphorus Loading in Spring Lake: Year 1
Get PDFThe rate of phosphorus release from sediments, and the degree to which alum reduces phosphorus release from sediments, was investigated in Spring Lake during the summer of 2003. Triplicate cores were sampled from 4 sites in the lake, and exposed to one of four treatments in the laboratory: 1) oxygen/alum; 2) oxygen/ no alum; 3) nitrogen/alum; or 4) nitrogen/no alum. Both soluble reactive phosphorus (SRP) and total phosphorus (TP) release rates were virtually undetectable in the alum treatments (both with and without oxygen). Low, but detectable, release rates were measured in the oxygen/no alum treatment. The highest release rates were measured in the nitrogen/no alum treatments; these rates translated to an internal load that ranged between 2.8 (low range) to 7.7 (high range) tons/year when extrapolated to a whole-lake basis. Internal phosphorus loads were approximately double that of previously estimated external phosphorus loads, and accounted for between 56 and 66% of the total phosphorus load to Spring Lake.
Uncertainties in our estimates are discussed, including spatial heterogeneity of sediment type, calculation of percent anoxia in Spring Lake, extrapolation of laboratory release rates to the whole lake, and external load estimates. We conclude that internal loading is a significant source of phosphorus to Spring Lake, and that alum is a potentially effective means of reducing this source. However, it is unknown how long an alum treatment would remain effective in this system. We recommend: 1) additional laboratory studies to obtain an estimate of how long an alum treatment would remain effective; 2) a pilot field study; and 3) continued efforts to reduce external loading to Spring Lake
