SAMPLE
Sludge/Debris Analysis
Customer: Customer
name
Project: Domestic well with pipeline plugging
Date: Feb. 23, 2004
Analysis by: David Hanson
Physical Comments:
Received a baggy filled with a very dense, red,
sludgy debris. Opened container, no apparent odors that could be due to
anaerobic bacteria. The debris appears to be sludge related to bacterial
activity.

Breakdown
Analysis
2.21.04 Saturday
|
|
0800
|
Mixed
a concentration of 5% of "Unicid" Granular and "Unicid"
Catalyst. Measured pH 1.3 |
|
0850
|
Placed
1/2 tsp of sludge into chemistry. Immediate brown discoloration which
simply means debris in suspension within chemistry. Immediate medium
effervescence which indicates carbonates (mineral deposit) or oxygen
(bacterial) present within sample. No odors noted. |
|
0900
|
Coloration
changing to a yellowish/brown which indicates debris going into solution
(iron). Medium effervescence continues. No odor noted. |
|
1215
|
Coloration
now mostly yellow (iron in solution). 80% of debris already dissolved.
No odor. Only minor effervescence now noted. |
|
1410
|
90%
of debris now dissolved. Color remains yellow. No odor, no effervescence
noted. |
|
1435
|
100%
of debris now dissolved. Coloration is yellow and clear as all debris
now in solution. pH 1.4 but within accuracy of meter so may not necessarily
have changed. End of test. |
Comments
We first physically inspect the debris to determine if it is mineral,
bacterial, or physical (corrosion by products or silts) to determine
a potential chemical direction. In this case, I believe that the debris
was related to bacterial activity. It dissolved rather easily in the
chemistry. We have the information on the well and the buried pipeline
and will fax a Project Proposal to outline a step x step process.
If you have any questions, please call. Thank you.
