R 4,1���
F. Lagoon Surface Area (using dimensions at inside top of bank): (acres)
(Draw a sketch of the lagoon on a separate sheet. list dimensions, and calculate surface area. The lagoon may
have been built different than designed, so measurements should be made.)
G. Estimate number of sampling points:
a. Less than 1.33 acres: Use 8 points
b. If more than 1.33 acres, _ acres x 6 = 8 , with maximum of 24.
(Using sketch and dimensions, develop a uniform grid that has the same number of intersections as the
estimated number of sampling points needed. Number the intersection points on the lagoon grid so that
data recorded at each can be easily matched.)
H. Conduct sludge survey and record data on "Sludge Survey Data Sheet" (Appendix 2). Also, at the location of
the pump intake, take measurement of distance from liquid surface to top of sludge layer and record it
on the Data Sheet (last row); this must be at least 2.5 ft. when irrigating.
I. At the time of the sludge survey, also measure the distance from the Maximum Liquid Level to the Present
Liquid Level (measure at the lagoon gauge pole):
J. Determine the distance from the top of bank to the Maximum Liquid Level
(use lagoon management plan or other lagoon records)
f
K. Determine the distance from the Maximum Liquid Level to the Minimum Liquid Level J + e)
(use lagoon management plan or other lagoon records)
L. Calculate the distance from the present liquid surface level to the Minimum Liquid Level 11 G _
(Item K minus Item I, assuming the present liquid level is below the Maximum Liquid Level):
M. Record from the Sludge Survey Data Sheet the distance from the present liquid surface level to the lagoon
bottom (average for all the measurement points): O '
N. Record from the Sludge Survey Data Sheet the distance from the present liquid surface level to the top of the
sludge layer (average for all the measurement points): 3:
O. Record from the Sludge Survey Data Sheet the average thickness of the sludge layer:`
P. Calculate the thickness of the existing Liquid Treatment Zone (Item N minus Item L):
Q. If Item 0 is greater than Item P, proceed to the Worksheet for Sludge Volume and Treatment Volume.
If Item 0 is equal to or less than Item P, you do not have t determine volumes.
