Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The Town of Pembroke's Wastewater Treatment Plant was clean and neat in appearance at the time of the
inspection. .All equipment was operational except one influent pum p that had been dam aged in an electrical
storm. -
RECOMMENDATION
Please change effluent tubing on sam pier more often to help avoid contam ination and ensure a true
representative sample is taken.
PAPER TRAIL REVIEW
DMR's for the months' of September 2005, Novem ber 2005, and January 2006 were compared to
laboratory bench sheets. All data was reported correctly except a chlorine residual on January 19; 2006.
The residual was reported as -greater than 20 micrograms instead of less than 20 Micrograms. Please
correct and-subniit an amended DM R.
