Charles Vandenburg "phoned in" a non -compliant Multiple DilutionWET result for
May. 'LMAC's NPDES limit is 2.6%, and the test failed at 0.92%. Because a
Priority Pollutant Analysis was performed during'the same week as the WET for May,
Charles will have moreinformation in the near future about the possibilities that'
can be eliminated as the cause. The WWTP effluent sulfide result that was sampled
during theweek of May's WET sampling was below detection level. Charles will
collect a sample for a sulfide analysis from the digester supernatant today. LMAC.
will begin a quarter in June with a Pass/Fail.WET.

LMAC June verbal "Pass" for the Aquatic Toxicity

Good news from LMAC, they received a verbal report that the aquatic toxicity was a
"Pass" for June (the beginning of a new quarter) So, they won't have to sample
again until September (the beginning of their next quarter). The problem is that
the cause for the previous three months of aquatic toxicity "Fail" results was not
determined, and it might occur again. . -

Sandy Mort.(ESB) evaluated several reports of laboratory data that Charles
Vanderberg sent to her this week. Her general findings were that there were
potential toxicants: Copper, Zinc, and Cobalt, and a possibility that there was
another toxicant(s) present that was not analyzed. The Conductivity was high
(sub -lethal toxicity begins showing up at around 1,600 microMHOS). The high
values of each toxicant, when combined, could have increased the toxic effect
during the Ceriodaphnia analysis ("Fail" for March, April, and May 2007). In
June, LMAC "Passed" it's quarterly Cerio analysis. (During the collection period
of the recent "Pass" composite sampling events, it appears that the toxicant
level(s) subsided.)

Dale, I looked at the sampling data, and wow, that's alot of metals! But then again, it's sludge, so it's
supposed to have high metals. What I think they need to do is look at the pounds of each pollutant
(metals and conventionals and nutrients) in X number of gallons of the sludge and compare this to
their MAHL remaining on their AT to find out how much the WWTP can take. Whichever pollutant
is the most restrictive, then that's the max flow they should put into the WWTP. And generally in any
case, they should start off with really low flows and watch the WWTP closely to see how it likes the
sludge.
Using zinc as an example, 9.13 mg/1 zinc times 0.5 mgd times 8.34 equals 38 pounds of zinc! Their
AT shows they only have 3.5456 lbs/day of zinc left after SIUs plus uncontrollable (their entire
MAHL is only 7.9814 lbs/day). But 0.025 mgd at 9.13 mg/1 is 1.9 lbs....and 0.005 mgd is only 0.38
lbs...much more do -able. Even so, maybe they want to start off even lower to let the WWTP
acclimate slowly.
Don't know exactly how they would figure out the oxygen demand, with such high CODs, BODs, and
Nitrogen, but I'm sure they can figure something out.

Hi Deborah and Sandy,
A few minutes ago I faxed laboratory results for the sludge that was recovered from the spill that
went into the swamp at LMAC near Laurinburg. It looks like the POTW will pump this sludge
into the new WWTP from the old Basins #1 & #2 (that were not in use). *The volume in each
basin -is approximately 500,000 gallons*.
Thanks,
Dale

Staff,
Comment back to me on the lab results you have received from the sludge (collected from the
abandoned WWTP) that is located in the two basins. Charles Vandeburgh is asking for our
assistance before it is fed back into the WWTP.

Dale, attached are the spreadsheets' of analytical data for the 2 basins and the
calculations of "hazard quotients" (HQ). 'There are numerous individual metals +
cyanide that result in HQs >1.0, as well as the sum of all HQs >1.0. HQs >1.0
indicate that the chemicals concentration in the samples exceed concentrations that
have been shown to cause toxicity. The concentrations were compared to toxicity
screening values routinely used for risk assessment investigations. Diluting the basin
contents so that the summed HQs are -<1 would presumably reduce the chemical
concentrations to levels where toxicity impacts would not be anticipated. (example:
Basin #1 the summed acute HQ = 482, so dilute basin#1 contents —500x to reduce.
potential acute toxicity to <1, or dilute 11,000x to reduce potential chronictoxicity to
<1).
Call me if you have questions.
