However, since samples are often lost due to seepage <br />meter damage or vandalism, a total of 40 samples is assumed for budget purposes. <br />6. Sediment collection / characterization: Lake bottom sediment core sample will be <br />collected at 25 sites in Queens Mirror Lake and South Lake Triplet using a 2 -inch <br />diameter stainless steel split -spoon core collector. Locations for sediment monitoring <br />sites are indicated on Figure 3. Visual characteristics of each sediment core will be <br />recorded, and the 0-10 cm layer of the sediment core will be sectioned off and collected. <br />This layer is collected since prior research has indicated that water quality impacts from <br />lake sediments are limited primarily to the top 10 cm. Each core sample will be placed <br />into a separate sample container and returned to the ERD research laboratory for analysis <br />of the following parameters: <br />a. Moisture Content ($12.50) d. Total Phosphorus ($20) <br />b. Organic Content ($12.50) e. Total Nitrogen ($25) <br />C. Sediment Density ($10) f. pH ($7) <br />Figure 3.
