i ; JRVEY LIS3ON I4ILLS coB 0 T LISBON FPIjLS, OCTOB 6, 19’71 ------- LISBON MIL lS, INC. LISBON FALLS, MAINE OCTOBER 8, 1971 On October 8, 1971, at the request of the U. S. Attorney for Maine, and with permission of Mr. Rainville, the president of Lisbon Mills, Inc., Donald Porteous and David Austin from the Environmental Protection Agency, Region I (New England), Needham, Massachusetts, sampled the discharge from the mill’s two effluent pipes which discharge into the Androscoggin River and, the Androscoggin River upstream of the mill (see Figure 1 and Table 1). Lisbon Mills, Inc . A brief reconnaissance showed that there were two major outfalls: one containing the wool wash water, the other spent water from the dye process. The outfall for the dye process (LF-Oi) and, the effluent from the wool wash process (LF-02) were sampled (Figure 2). Both the wool wash and dye operations are batch processes. The effluents were sampled during the dumping of some of these batches. Flows were determined using the California Pipe Method. Androscoggin River The Androscoggin River was sampled in Lisbon Falls, Maine, directly upstream of Lisbon Mills, Inc. (Figure 3). The upstream sample (LF-Ol ) was obtained off the comp 3 wneL..bxidge connecting the town road with the main office of the mill. Sampling Procedures Samples were collected at all stations for bacteria, dissolved oxygen (DO), biochemical oxygen demand. (BOD), and total nonfi] .terable residue analyses. The Androscoggin River samples were also analyzed for total ------- phosphorus. The temperature of each sample was taken in the field using a metal thermometer. All samples were returned to the Needham lab for analysis the same day as the sampling. The Lisbon Mills samples were hand-dipped in their shipping and storage containers. The Androscoggin River samples were collected by means of a Keum erer- type sampler and divided into their shipping and storage containers. Sample Preservation The DO samples were preserved using 2 ml inanganous sulfate and 2 ml alkali-azide reagents. The total phosphorus samples were preserved with 5 in]. chloroform reagent. All samples were iced. Sample Identification Each sample was tagged with one chain of custody tag indicating collecting agency, lab number, time, date, source of sample, collector’s signature and title, witness’ a signature and title, plus information on the transfer of the sample. In addition, a pre-numbered. field data card was filled out for each collection time to record the temperature of the sample and the sampling location. Results The results of the effluent and river water analyses are s n n s rized in Tables 2 and 3. The company discharges at a rate of over 1 OO pounds per day of suspended solids to the Androscoggin River. Total nonfilterable residue is a measure of the suspended solids in the sample. Suspended solids discharged in the raw waste from a wool textile mill usually include wool fibers, foreign matter cleansed from the wool and -2- ------- miscellaneous particulate matter washed into the sewer during clean-up operation. In the stream, the suspended solids interfere with the normal stream ecolo r by preventing light penetration. Some of the suspended solids settle out covering the bottom with a layer of sludge, idiling the benthic organisms and thus eliminating an important food supply for fish. In addition, the organic solids which settle out, decompose causing an oxygen demand on the overlying water that may result in a hostile environment for clean water organisms. The oxygen demand, of sewage and industrial wastes, as measured by the biochemical oxygen demand test (BOD), indicates the waste’s potential for reducing the dissolved oxygen content of the receiving water. Adequate dissolved oxygen levels are necessary to support fish and other aquatic life. If dissolved, oxygen becomes totally depleted, hydrogen sulfide gas is produced creating obnoxious odDrs and unpleasant environments for persons living or working nearby. The hydrogen sulfide given off may turn nearby houses, bridges or other painted structures black. The averages of the effluent BOD’s from Lisbon Mills were higher than the normal BOD of raw domestic sewage. Since the mill operates as a batch process system, the effluent samples will vary in consistency depending upon when the samples were taken. The dye process effluent (LF-o1) was purple and t had colored. the ground around the outfall a deep purple. -3- ------- TABLE 1 STATION LOCATION Station Latitude Longitude Description p I 0 I IT LF-O1 1 3 59 141 70 03 140 Dye effluent, Lisbon Nills, Inc.
