b. Distance from the lagoon liquid surface to the bottom (soil) of the lagoon.
previous survey
c. Thickness of the sludge layer if making a direct measurement with "core sampler".
NIA
F. Lagoon Surface Area (using dimensions at inside top of bank): 1.8 (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 ac. acres x 6 = 1020 , 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. Numberthe 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 measurements 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.
1. At the time of the survey, also measure the distance from the Maximum Liquid Level to the Present Liquid
Level (measure at the lagoon gauge pole): 1.0
J. Determine the distance from the top of bank to the Maximum Liquid Level 1.6
(use lagoon management plan or other lagoon records)
K. Determine the distance from the Maximum Liquid to the Minimum Liquid level: 2.2
(use lagoon management plan or other lagoon records)
L. Calculate the distance from the present liquid surface level to the Minimum Liquid Level 1.2
(Item K Minus Item I, assuming the present liquid level is below the Maximum Liquid Level)
M. Record from the Sludge Surrey Data Sheet the distance from the present liquid surface level to the
lagoon bottom (average for all the measurement points) 10.2
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): 4.5
0. Record from the Sludge Survey Data Sheet the average thickness of the sludge layer: 5.7
P. Calculate the thickness of the existing Liquid Treatment Zone (Item N minus Item L): 3.3
Q. If Item O is greater than Item P, proceed to the Worksheet for Sludge Volume and Treatment Volume.
If Item O is equal to or less than Item P, you do not have to determine volumes.

Appendix 3. Worksheet for sludge volume and treatment volume
Revised August 2008
The average thickness of the sludge layer and the thickness of the existing liquid (sludge -free) treatment zone are determined
from the Information on the Lagoon Sludge Survey Form ( Items O and P, respectively). In this example, the average sludge
layer thickness is 2.5 feet and the existing liquid treatment zone is 3.5 feet. If the lagoon has a designed sludge storage volume,
see notes at end of the worksheet. The dimensions of the lagoon as measured and the side slope are needed
for calculations of sludge volume and of total treatment volume. If the lagoon is a standard geometric shape, the sludge
volume and the treatment volume in the lagoon can be estimated by using standard equations. For approximate volumes
of rectangular lagoons with constant side slope, calculate length and width at the midpoint of the layer, and multiply by layer
thickness to calculate layer volume, as shown in the example. For irregular shapes, convert the total surface area to a square
or rectangular shape. For exact volumes for lagoons with constant side slope, the "Prismoidal Equations" may be used.

15. Ratio ( R ) of sludge layer volume to total Treatment Volume

If the ratio R exceeds 0.50, than a sludge Plan of Action may be required. Check with DWQ for information
on filing the Plan of Action.
Note: If the lagoon has a designed sludge storage volume (DSSV), subtract that volume from both the volume
of sludge (Vs) (Item 8) and from the volume of total treatment zone (Vz) (item 14), and take the ratio.
Then, R = (Vs-DSSV)1(Vz - DSSV)
Example: If DSSV = 85,000 ft3, then R = (169,860 - 85,000)1(447,174 - 85,000) = 84,8601362,174 = 0.24.
