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.
