I NTRODUCTI ON
On May 7, 1973, Jim Armstrong and I met Weyerhaeuser (Weyco) rep~ ntatives Roy Reinersten and Bruce Martinell at their Snoqualmie mill to di~.ss the proposed survey. On nay 8 tine survey was conducted as requested, but it was imposs~ ~e ~ determine flow at several locations and the depth of sludge build-~ i~ the pond was ~c,tdetermined.

Samples were obtained from the ditch in the boil from the discharge. #10 Discharoe from powerhouse.

Coliform samples were taken from catwalk at midchannel. #11 Combined discharge southwest of “mill” area.- #12 Sewage treatment plant discharge. This station was not sampled because arrangements are being made to connect to the city lagoons. #13 Intake water from pond.

This difference is explained by the fact that on stations 1 , 2, and 9, the lab solids were run on the composite and the field solids were determined on grab samples. Station 11 settleable solids are different, but tests were run on two different grab samples. The ph values obtained in the field were consistently lower than lab values. This is possibly explained by biological and chemical changes which occurred during storage and transport even though the samples were iced. The flow values were computed by measuring the dimensions of a channel and multiplying by the velocity. Although they are rough estimates, flows are reported to two places to give better comparisons. Inter- mittent rain fell on the day of the survey.

The treatment ditch appears to reduce settleable solids, 800, and COD. The effluent from the log pond is characterized by the data for Station #1. The coliform data presented in Table III reflect the water “quality” of the log pond. Page five Memo to Bill Burwell June 21, 1973 PERSONAL COMMENTS Background June 6, 197 Pat Lee and I did a survey on the sewage treatment plant and composited the log pond effluent at the weir. Additional stations were established in the log pond and grab samples were taken. The results of this survey indicated that the efficiency of the STP was marginal and that disinfection was inadequate. The following field data were reported on the log pond effluent from 1100 hours to 1900 hours. Max Mm Mean Median Temp (C0) 19.8 19.1 19.6 19.8 pH 7.1 6.2 6.7 Conductivity (iimhos/cm) 140 125 130 130 Settleable Solids (rnl/l) .3 .1 .1 .1 Laboratory data on the effluent composite from 1300 hours to 1900 hours were: BOO - 13 ppm Sp. Conductivity — ll2~mhos/cm COD - 100 ppm Turbidity — 36JTU TS - 183 ppm pH — 7.1 TNVS — 97 ppm TSS - 36 ppm NVSS - 40 ppm Total coliform samples taken from the outfall were run in the motel using the Millipore Field Kit. Values are reported in colonies/lOOmls. TIME TI ME 1130 — <20,000 1430 - 22,000 1230 - 26,000 1730 - <20,000 1330 — 31 ,000 1830 - <20,000 The overall quality of the log pond effluent was better during this previous survey. The BOO, COD, Solids, Turbidity, and coliform were all lower. The pH was also within the acceptable range for discharge, contrary to field data obtained in 1973. Page six Memo to Bill Burwell June 21, 1973 Flow Estimation Flow estimates are rough. The area of water was measured with a tape measure and/or yardstick. The velocity was computed by timing a float- ing object (cigarette filter) dropped in midstream, and measuring the length of travel. Time was doubled in each case, because the velocity of the general waterway was obviously slower than at the surface midstream. Although the method was crude, the estimates are somewhat relative and better than an eyeball guess. The use of a 900 “V” notch weir pipe inserts was not possible because the culverts all had flows exceeding the capacity of the weirs. The use of a gurley meter was impossible in shallow depth flows. Also in the settling ditch, the amount of sludge build-up made wading difficult and would have also biased gurley meter readings. Methods use in calculation are attached. Col iform The exceeding high numbers of coliform present a potential health hazard to the employees working in and around the log, pond. Comparing these numbers to the effluent from the White River operation, the values are gross; this is due to the discharge of inadequately disinfected domestic sewage. A ratio of fecal to fecal streptococci of greater than 4.4 indicates that the source of bacterial contamination is of human origin. The ratios obtained from Station lOA surface and bottom are 4.6 and 5.0 respectively. Considering that fecal streptococci do not multiply in water, the values obtained near the powerhouse are very high. An apparent die-off is observed before discharge from the log pond, but the numbers of total coliform (55,000; 50,000; 60,000 colonies/l00 mls) are still gross. The proposal of connecting the domestic sewerage to the city treatment system will improve the bacterial quality of the pond considerably; but, in the interim, the chlorine addition rate on the STP should be increased. There is little danger of damaging any biota of the pond by adding excess- ive chlorine. An effort should be made to encourage the industry to inform their employees who have potential contact with the long pond waters of the health hazard which exists. 2 V C) r. “U 0— ) Li K~ ‘N N: V -, ( Tokuh> .~N —‘ V ‘C -. - 7- -?~, I ‘I V 7’~ ( -:?> / --7—- —7 7- ‘K, V / ‘C-—..- / / / 7- F A A ~4,~~ V. 2’ Sx~~c’quaV~e 4. , C.

To characterize the wastes being discharges at the unit process level. 2. To determine the degree of treatment, if any, is being achieved by the current settling ditch. 3. To characterize the effluent from the Snoqualmie Log Pond. 4. To evaluate the water quality in the Log Pond. BACKGROUND In terms of industrial waste water disposal, the Weyerhaeuser Mill at Sno— qualmie, until now, has been all but ignored by this Department. The process effluents have not been adequately an&l~zed nor has the treatment ~iystembeen evaluated. The operation consists of a saw mill and power house, a plywood mill, a hydraulic barker and a wood fiber processing operation. The power house has a thermal discharge at times, a blow down discharge and small quantities of bear- ing water. The saw mill discharges saw guide water and cooling water. The ply- wood operation has phenolitic glue wastes associated with it along with dryer condensate, log conditioning discharges, and small amounts of cooling water. The most significant discharge is associated with the hydraulic barker, the dis- charge being treated by means of a settling ditch. The “sylvacel” or wood fiber plant produces small quantities of cooling water. In addition to these effluents, a discharge occurs from the log washer and oil problems are associated with a number of the processes.

Burwell EXPECTED RESULTS The most important parameters involve charterization of discharges from the various operations and characterizing the effluent from the log pond. The results should be in two formats. The first should include all the data and observations taken at the time of sampling. The second should be any comments, statements as to corrective action and reflective observations. Such a division Page 3 April 17, 1973 in the report allows for the data portion only to be transmitted to the industry. STUDY COMPLETION DATE By May 15, 1973, so as to insure pond overflow.
