Attention Brad Luckey
Dear Mr. Luckey,
On 22 January 2014 Engineering Consulting Services (ECS) submitted samples from PTI
for BOD testing. Due to laboratory QA/QC,,problems no data is available for those
samples. It appears that due to laboratory contamination all oxygen was depleted from
all samples and dilutions, therefore, BOD concentrations were unable to be calculated.
Samples were not able to be re -tested due to the 48 hour holding time requirement for
BOD testing.
RAL apologizes for any inconvenience this may have caused ECS and will do everything
possible to avoid this from happening in the future.
Sincerely,
Sidney L. Champion
Director of Laboratory Services
