At the request and support of the Soil Conservation Service (SCS) , a bacterial water quality study was conducted to determine the bacterial quality of the stream waters within the watershed, the adequacy of the water quality for contact recreation, and possible control measures to implement if the quality proved unsatisfactory. Waters subjected to fecal contamination originating from livestock, wildlife and/or humans are characterized by the presence of bacteria which inhabit the intestinal tracts of warm-blooded animals. The coliform group of bacteria is discharged in large numbers in warm- blooded animal excreta.. This bacterial group contains several genera with similar biochemical properties. Results of work by Eijkman(2), Hajna and Perry(3), Clark, et. al. (4), Geldreich, et. al.(5)(6), and Geldreich(7) have enhanced the differentiation of the coliform bacteria group into subgroups of fecal and non-fecal origin. The fecal coliform bacteria group is presently the most reliable bacterial measure of fecal contamination in environ- mental waters. Though most are non-pathogenic, coliform bacteria indicate the probable presence of enteric pathogens resulting from contamination by fecal material. Some enteric pathogens, if ingested, may cause ------- 2 gasteroenteritis, dysentery, typhoid fever, and/or paratyphoid fever. Although not necessarily caused by enteric pathogens, ear, eye, nose, throat and skin infections are commonly contracted from contact with polluted waters. Viral diseases, such as infectious hepatitus, may also result from ingestion of waters subjected to fecal contamination. The most widely accepted bacterial criterion for environmental waters used for primary contact recreation is based on the fecal coliform group. A recommended level of fecal coliform bacteria not to exceed a log mean of 200/100 ml, based on at least five samples collected during any 30-day period, nor more than 10 percent of the total number of samples exceeding 400/100 ml is regarded as offering the bather reasonable safeguards. It should be noted that no environmental water should be considered completely safe for primary contact recreation regardless of the bacterial indicator density of the water. There will be some health risks involved for the water user; however, the risks should be reduced in waters with low indicator densities. All samples collected for microbiological analysis were examined for fecal coliform and fecal streptococci bacteria densities. Examina- tions for the presence of Salmonella, an enteric pathogen, were made at selected stations. ------- 3 SUMMARY AND CONCLUSIONS SUMMARY 1. At the request of the U.S. Department of Agriculture, Soil Con- servation Service, preimpoundment bacteriological studies were conducted during July 1971 and May 1972 at the sites of two proposed multipurpose impoundments in the Upper Leaf River Watershed in Smith County, Mississippi. 2. A waste inventory of the drainage areas for the two impoundments disclosed no municipal or industrial waste sources. Waste sources within the drainage areas are limited to agriculturally related activities and wildlife. 3. Some streams within each drainage are used as receptacles for solid waste disposal (e.g. household garbage, animal carcasses, and automobile parts). Impoundment Site 8 4. The mean fecal coliform bacteria densities at stations within the Site 8 impoundment area ranged from 13/100 ml (Station 05) to 660/100 ml (Station 03). 5. The mean fecal coliform densities were generally higher during the July 1971 than during the May 1972 study. 6. The ratio of mean fecal coliform to mean fecal streptococcus densities within the Site 8 impoundment area ranged from 0.14:1 to 2.60:1. ------- 4 7. Salmonella were isolated at all sampling stations within the Site 8 impoundment area. Serotypes identified were: J3. give, J3. luciana, Su muenchen, S^. gaminara, S_. newport, J5. bredeney, _S. java, jS. infantis, J3. bareilly, and j>. heidelberg. 8. Estimated streamflows within the Site 8 impoundment area ranged from 0.3 to 1.2 cfs during the July 1971 study and from 0.3 to 4.8 cfs during the May 1972 study. Impoundment Site 4 9. Sample sites selected within the Site 4 impoundment area were not sampled during the July 1971 study due to lack of flow. Sampling at several stations within this area during May 1972 was possible only after a period of rainfall. 10. The mean fecal coliform densities ranged from 2800 to 8200/100 ml at the sampling stations within the Site 4 impoundment area during May 1972. 11. The ratio of mean fecal coliform to fecal streptococci densities within the Site 4 impoundment area ranged from 1.37:1 to 2.68:1. 12. One station (Station 07) within the Site 4 impoundment area was sampled for the presence of Salmonella. Inverness was identified from this station. 13. Estimated screamflows ranged from 0 to 7.0 cfs at the sampling sites within the Site 4 impoundment area during the May 1972 study. ------- 5 CONCLUSIONS 1. After completion of each impoundment, the retention time in each reservoir will result in a decrease in bacterial densities and general improvement of the bacterial water quality. 2. The headwaters of the reservoirs should not be used for primary contact recreation under any circumstance. 3. Commercial and land developments along each impoundment periphery and within each drainage area should be adequately controlled if bacterial water quality is to be maintained. 4. Localized use of chicken litter as agricultural fertilizer may serve as a contributor of bacterial pollution within each impound- ment drainage area. Attempts should be made to arrive at agree- ments with landowners to apply these wastes only during the non-recreational season. 5. The continued use of streams as solid waste receptables will degrade the water quality within each drainage area. Efforts should be made by the appropriate authority to halt this practice of waste disposal. Impoundment Site 8 6. Projected bacteriological quality in the Site 8 impoundment area will be of sufficient quality to support recreational water contact activities. The bacteriological quality of the impoundment should be well within the recommended limits (a monthly mean fecal coliform level not to exceed 200/100 ml) for primary contact recreation. ------- 7. The bacterial water quality of the streams within the proposed Site 8 impoundment area indicate no major waste sources. The mean fecal coliform bacteria densities were less than 400/100 ml except at one station during both survey periods. 8. The mean fecal coliform bacteria density of 940/100 ml at Station 03 during the July 1971 survey apparently resulted from a localized problem associated with solid waste disposal and wildlife. The results of the May 1972 survey indicated no bacterial problem at this station. 9. A waste source inventory indicated the fecal contamination within the Site 8 impoundment area resulted from non-human sources. Fecal coliform to fecal streptococci ratios further support this conclu- sion. 10. The isolation of Salmonella serotypes within the Site 8 impoundment area is indicative not only of fecal pollution but establishes a potential for disease transmission. Impoundment Site 4 11. Projected bacteriological quality in the Site 4 impoundment area will be marginal for the support of recreational water contact activities. Based on existing bacterial densities and hydrologic conditions in the streams tributary to the proposed impoundment, the impoundment will be subjected to periodic rapid influxes of runoff carrying extremely high densities of pollution indicator organisms. Recommended use of this proposed impoundment of water ------- 7 contact recreation should be delayed until sufficient post- impoundment studies are conducted that demonstrate sufficient water quality to support primary contact activities. 12. Soil characteristics within the Site 4 impoundment drainage area promote a rapid runoff of precipitation. Streamflows within the drainage areas are almost entirely dependent upon surface runoff. 13. Fecal wastes from domestic animals and wildlife within the Site 4 impoundment drainage area results in a pronounced degradation of the bacterial water quality of the streams during periods of surface runoff. ------- 8 AUTHORITY The U.S. Environmental Protection Agency study of the Upper Leaf River Watershed preimpoundment areas was performed at the request of the U.S. Department of Agriculture, Soil Conservation Service. Authority for such studies is contained in Section 5(a) of the Federal Water Pollution Control Act as amended (33 USC 466 et. seq.). ------- 9 STUDY AREA The two study areas for the proposed multipurpose impoundments are located in the Upper Leaf River Watershed in Smith County, Mississippi. Figures 1 and 2 depict these study areas. Impoundment Site 4 is located approximately three miles northeast of Pineville, Mississippi, in primarily forested and pasture lands. The site is situated in the Forest Hill geologic formation comprised of sandy and silty clays. The dam site will be located on Ichusa Creek. The drainage area to be regulated by this structure will be approximately 9,364 acres located in Smith and Scott Counties. The surface area of the completed impoundment will be approximately 800 acres. Impoundment Site 8 is located approximately five miles northeast of Raleigh, Mississippi, in primarily forested and pasture lands. The site falls within the Vicksburg geological group containing a mixture of sandy clays and non-plastic sands. The dam site will be located on Shongelo Creek. The drainage area to be regulated by this structure will be approximately 7,690 acres and the completed impoundment will have a surface area of approximately 345 acres. Sampling station locations for both study areas are contained in Table I and shown in Figures 1 and 2. ------- TABLE I STATION LOCATIONS Station Location 01 Shongelo Creek 0.5 mile downstream from the confluence of Big Shongelo and Little Shongelo Creeks at County Road Bridge (Section 33,T3N,R8E). 02 Little Shongelo Creek 0.6 mile upstream from the confluence with Big Shongelo Creek at County Road Bridge (Section 29, T3N,R8E). 03 Big Shongelo Creek 0.8 mile upstream from the confluence with Little Shongelo Creek (Section 29, T3N,R8E). 04 Big Shongelo Creek 1.5 miles upstream from Station 03 at County Road Bridge 1.2 miles from State Highway 35 (Section 17,20,T3N,R8E). 05 Shongelo Recreational Area Lake at spillway (Section 18, T3N.R8E). 06 Big Shongelo Creek at U.S. Forest Service Road 539A (Section 8,T3N,R8E). 07 Ichusa Creek at County Road Bridge 1.1 miles from State Highway 501 (Section 28,T4N,R9E). 08 Ichusa Creek at County Road Bridge 0.8 mile upstream from Station 07 (Section 28,T4N,R9E). 09 Unnamed creek tributary to Ichusa Creek at County Road culvert 0.6 mile from State Highway 501 (Section 20,T4N,R9E 10 Unnamed creek tributary to Ichusa Creek at U.S. Forest Service Road 520 Bridge (Section 9,T4N,R9E). ------- FIGURE I • J3 6 \ \ ,A ¦' 1 \ COf ~\ I > I I Shongelo Lake BIENVILLE NATIONAL FOREST 1/2 SCALE IN MILES 0 1/2 U.S ENVIRONMENTAL PROTECTION AGENCY REGION EC IMPOUNDMENT SITE 8 STUDY AREA SURVEILLANCE AND ANALYSIS DIVISION ATHENS GEORGIA ------- figure 2 ------- 10 WASTE SOURCES A waste source inventory revealed no industrial or municipal wastes are discharged within the drainage areas of the proposed impoundments. The inventory revealed some agriculturally related waste sources within each drainage area. Within the Site 4 drainage area there are two poultry farms with approximately 30,000 broilers per farm. These are closed operations and the poultry litter is removed about twice a year and routinely spread onto pasture land. In addition, there are 12 farms with approximately 30 head of cattle per farm. There are no swine operations within this drainage area. The Site 8 drainage area has one poultry farm with approximately 1500 laying hens. Litter from this operation is removed about twice yearly and spread onto pasture land. There are six farms with about 20 head of cattle per farm and there are four general farming opera- tions. There are no swine operations located within this drainage area. There appeared to be abundant wildlife populations inhabiting both drainage areas. ------- 11 STUDY FINDINGS Bacteriological water quality studies were conducted at two proposed impoundment sites in the Upper Leaf River Watershed from July 13 through 19, 1971, and May 1 through 4, 1972. Bacteriological samples were collected and quantitatively analyzed for fecal coliform and fecal streptococci bacteria as described in Appendix A. Qualitative determinations for members of the genus Salmonella were made at seven selected stations. The isolation and identification methods are described in Appendix A. In addition, water temperatures were recorded and, where possible, stream flows measured. The initial study was terminated in July and rescheduled because of the lack of any streamflow in the Site 4 drainage area. The Site 8 drainage area streams had flow and were sampled during the July 1971 study. During the May 1972 study, there was streamflow in the principal stream (Ichusa Creek) in the Site 4 drainage area. In addition, approximately one inch of rainfall in the Site 4 drainage area during this study period resulted in adequate streamflows for a short time (Appendix B). The effect that surface runoff had on the bacterial quality of the streams in this area was determined. All Site 8 stations had adequate flow and were sampled during this study. ------- 12 IMPOUNDMENT SITE 8 Bacterial Results Coliform Bacteria The fecal coliform bacteria data summaries for the July 1971 and May 1972 studies are presented in Tables II and III. In general, the mean fecal coliform bacteria densities were slightly lower at the different stations during May 1972 than during July 1971. This is graphically illustrated in Figure 3. The combined data summary for the two studies are presented in Table IV. All fecal coliform data are contained in Appendix C. Station 01, located on Shongelo Creek immediately downstream from the proposed dam site, had a meani^ fecal coliform bacteria density of 320/100 ml for the entire study (Table IV). This density reflects the combined tributary bacterial input for the drainage area since all tributaries flow into Shongelo Creek above this point. Little Shongelo Creek as measured at Station 02 contributed a mean fecal coliform bacteria density of 340/100 ml. There was little difference between the July 1971 and May 1972 mean fecal coliform densities at this station (Tables II and III). Station 03, located on Big Shongelo Creek had a combined mean fecal coliform density of 660/100 ml (Table IV) which was the highest of any station in the Site 8 study area. As seen in Tables II and III All means referred to in this report are geometric means. ------- TABLE II Impoundment Site 8 Bacteriological Data Summary - July 1971 Study Fecal Coliform Bacteria/100 ml Fecal Streptococci Bacteria/100 ml Station Maxi- mum Mini- mum Aver- age Geo.

There are several factors to note regarding July 1971 mean fecal coliform bacteria density of 940/100 ml. First, an elevated fecal coliform density was measured on July 19 which resulted from surface runoff produced by heavy rainfall (Appendix C). In addition, there was clandestine disposal of solid waste within the immediate vicinity of Station 03. The waste consisted of dead poultry, poultry viscera, feathers, and household garbage. Samples were collected upstream of these wastes; however, numerous animal tracks were evident along both banks of the creek and there were indications that animals were scavenging the wastes. In contrast, during the May 1972 study, there was no evidence of any recent waste disposal at this station and the mean fecal coliform bacteria density was 330/100 ml. Station 04, °n Big Shongelo Creek 1.5 miles upstream from Station 03, had a mean fecal coliform bacteria density of 270/100 ml for the entire study period. The mean fecal coliform density at this station was higher during the July 1971 study than during the May 1972 study (Tables II and III, Figure 3). Station 05 was located at the concrete spillway at Shongelo Recreation Area Lake. The mean fecal coliform density of 13/100 ml was indicative of little fecal contamination. As shown in Figure 3, the mean fecal coliform bacteria density was slightly higher in the July 1971 study than in the May 1972 study. Swimmers were observed on several different days during the July 1971 study; however, none were seen during the May 1972 sampling period. ------- FIGURE 3 FECAL COLIFORM BACTERIA DENSITIES AT IMPOUNDMENT SITE 8 STATIONS DURING JULY, 1971 AND MAY, 1972 STUDIES 12 3 15 6 STATIONS ------- 14 Station 06, located on Big Shongelo Creek within the Bienville National Forest, had a mean fecal coliform bacteria density of 220/100 ml. There was little difference between the July 1971 and May 1972 mean densities at this station. Fecal Streptococcus Bacteria Fecal streptococcus bacteria analyses were performed to aid in establishing whether pollution in the study areas was primarily of animal or human origin. It has been found that fecal coliform to fecal streptococcus (FC/FS) ratios are useful in indicating the origin of fecal pollution. A fecal coliform to fecal streptococci ratio of greater than 4.0 is regarded as evidence of pollution derived primarily from human origin, whereas an FC/FS ratio of 0.7 or less suggests pollution derived predominantly or entirely from livestock, wildlife, and/or poultry.(7) Ratios just below 4.0 are still sug- gestive of waste primarily of human origin, and ratios slightly greater than 0.7 are still suggestive of wastes of animal origin. A truly "gray-area" of interpretation is in the ratio range of 1.0 to 2.0. Interpretation of ratios in this area should be used with great caution. Any ratio must be applied in areas where the time of travel from the wastes sources at the sampling points is less than 24 hours because of the differences in die-off rates of the two bacterial groups. The mean fecal streptococci bacteria densities for each study period and the entire study period are contained in Tables II, III ------- 15 and IV. As was the case with fecal coliform densities, the mean fecal streptococci bacteria densities were consistently higher during the July 1971 study than during the May 1972 study (Tables II and III). Station 03 had the highest mean fecal streptococci density (2800/100 ml) for the July 1971 study period. As previously mentioned, the clandestine dumping of solid waste within the immediate vicinity of this station possibly indirectly influenced the fecal streptococci densities. The fecal coliform to fecal streptococci ratios for the entire study period are contained in Table V. With one exception, the ratios obtained were 0.35 or less which indicates pollution originating predominantly from livestock, wildlife, poultry, and other non-human fecal material. This agrees with the results of the waste source inventory which indicated an absence of domestic wastes. Station 05 had a ratio within the "gray-area" of interpretation. The "gray" FC/FS ratio at this station resulted from the very low mean fecal coliform and fecal streptococci densities obtained and no clear interpretation would be expected. Salmonella Isolation In addition to the determinations of fecal coliforms and fecal streptococci, special efforts were made to detect members of the genus Salmonella at selected stations. Salmonella is a large serologically related genus comprised of some 1,300 serotypes. Salmonella is probably the easiest enteric ------- TABLE V COMPARISONS OF THE GEOMETRIC MEAN FECAL COLIFORM AND FECAL STREPTOCOCCI BACTERIA DENSITIES FOR THE ENTIRE STUDY PERIOD Station 01 02 03 04 05 06 Geometric Mean Fecal Coliforms per 100 ml 320 340 660 270 13 220 Geometric Mean Fecal Streptococci per 100 ml FC /FS* 1,100 0.29 1,100 0.31 1,900 0.35 1,800 0.15 5 2.60 1,600 0.14 *FC/FS - Geometric mean fecal coliform bacteria/100 ml Geometric mean fecal streptococci bacteria/100 ml ------- 16 pathogen to isolate from environmental waters. All Salmonella are considered pathogenic for man, animals, or both. The presence of Salmonella is proof of fecal contamination and establishes the disease-producing potential of the water. Table VI lists the stations where Salmonella isolation was attempted and the serotypes isolated. Several facts should be noted regarding the Salmonella isolations. Six serotypes were isolated at Station 02 on Little Shongelo Creek during the July 1971 survey. No definitive explanation can be given for the variety of isolates at this station. However, there were uncon- firmed reports of a beaver-dam upstream of this station and the possibility of beaver as the source of the Salmonella exists. The recovery of two Salmonella serotypes at Station 05 when the mean fecal coliform bacteria density was 25/100 ml simply underscores the fact that low indicator levels alone do not negate the possibility of enteric pathogen presence. Flow Determinations The average estimated streamflows for the July 1971 and May 1972 studies are shown in Table VII. In July 1971, average flows ranged from 0.3 cfs at Station 06 to 1.2 cfs at Station 01. The average flows during the May 1972 survey were from two to four times greater than the July 1971 flows.

On July 19 one sample was collected at Station 07 (Ichusa Creek immediately downstream of the proposed damsite). There was flowing water at this point as a result of rainfall which occurred on the night of July 16, and the morning of July 17 (Appendix B). The fecal coliform bacteria density of the sample was 1100/100 ml (Appendix C). The bacterial data summary for the May 1972 study is contained in Table IX. During the first two days of the May 1972 study there was only one flowing point (station 07). As a result of rainfall in the area, during the second day of sampling, four flowing points were sampled to determine the effect of surface runoff on the bacterial quality of the water. Figure 5 illustrates the impact of the surface runoff on stream flow and fecal coliform density at Station 07. As shown, the fecal coliform bacteria density increased from 350/100 ml before the rain to >50,000/100 ml in approximately 24 hours. Within the next 24 hours the fecal coliform bacteria density had decreased to 3100/100 ml. The fecal coliform density at Stations 08, 09, and 10 followed basically the same pattern of extremely high densities during the first 24 hours of runoff and decreasing densities in the succeeding 24 hours (Table X). The effects of the surface runoff on the bacterial quality of the water was quite dramatic since lack of base flow precluded any dilution of the runoff. These high bacterial densities would be expected after each rainfall within this drainage area. ------- TABLE IX Impoundment Site 4 Bacteriological Data Summary May 1972 Study Fecal Coliform/100 ml Fecal Strept ococci/100 ml No. of FC/FS* Sta.

The mean fecal streptococci densities ranged from 1400/100 ml at station 07 to 5900/100 ml at station 10. The fecal coliform to fecal streptococci ratios presented in Table IX ranged from 1.37 to 2.68. All ratios were in the "gray area" of interpretation and no conclusions using these ratios could be drawn as to the origin of the fecal waste. This is as expected since most the bacterial densities enumerated at the Site 4 stations resulted from multiple fecal wastes scoured from the drainage area by sur- face runoff. Salmonella Isolation Isolation for the genus Salmonella was attempted at Station 07 only, since this was the only station with base flow during the May 1972 study. Salmonella inverness was isolated at this station. No attempt was made to isolate Salmonella at the Site 4 stations during July 1971. Flow Determination There was no base flow at 3 of the Site 4 stations during the July 1971 study. There was some flow, estimated to be <0.1 cfs, at Station 07 following rain in the drainage area. During the May 1972 study there was base flow at Station 07, only (estimated to be <0.1 cfs). While this study was being conducted approximately 1.0 inch of rainfall occurred within the Site 4 drainage area. As a result of surface runoff, the streamflow at Station 07 ------- 20 peaked at approximately 7.0 cfs (Figure 5). The peak flows at Stations 08 and 10 were estimated at 6.0 cfs and 20 cfs, respectively (Appendix C). No flow determinations could be made at Station 09. Within 72 hours after the beginning of the rainfall, there was no flowing water at Stations 09 and 10. Temperature Water temperatures at the Site 4 stations ranged from 14.5°C to 24.5°C. The average temperatures ranged from 17.4°C to 18.8°C (Appendix C). PROJECTED BACTERIOLOGICAL WATER QUALITY OF THE PROPOSED IMPOUNDMENTS IMPOUNDMENT SITE 8 Existing bacterial water quality within the drainage area together with runoff data and proposed reservoir volume is used as a base for estimating future impoundment bacterial quality. Runoff data from the Upper Leaf River Watershed for the period 1951-1960 were used to obtain an estimate of runoff within the impoundment drainage area. (8) An average runoff for the months of June, July, and August are used for predictive pruposes. Records show that an average 0.50 inches of runoff per month occurred during the recreation season of the above 10-year period. Impoundment drainage area and projected reservoir volume data were obtained from the Soil Conservation Service.(1) The drainage ------- 100 0 W- 100,000 FIGURE 5 COMPARISON OF THE FECAL COLIFORM DENSITY AND FLOW AT STATION 07 DURING THE MAY 1972 STUDY > 50,000 50,000 10 0 10,000 — : 5 o o o 5 ce o o o < o i o - 1,000 Fecal Coliform Density Flow 0 I »- 100 1200 5/1/72 2400 L- 1 ' ' 1200 5/2/72 i 2400 1200 5/3/72 1 2400 1200 5/4/72 I 2400 ------- 21 area for Site 8 is 7690 acres and the projected recreational pool volume is 3062 acre feet. Applying the following mixing equation, some rough estimates can be made. Cl^l + ^2^2 Ql + Q2 C]_ = mean FC density of runoff Ql = acre feet of runoff during recreation season C2 = mean FC density of the impoundment when filled (estimated to be 25/100 ml when not under heavy runoff influence) Q2 = acre feet of impoundment at normal recreation pool level Applying a mean runoff fecal coliform density of 660/100 ml (highest mean density measured during the entire study), an estimated mean FC density of 31/100 ml would occur throughout the lake. Naturally, such a projection assumes complete and instantaneous mixing of runoff and reservoir water and no bacterial dieoff. Consequently, such a projec- tion would be considered excessively high for the reservoir as a whole. In actuality, counts would be highest near tributaries and lowest near the impoundment outlet. Nevertheless the above technique provides useful information. Using a mean runoff FC density of 5000/100 ml, a value higher than any density measured at the Site 8 stations during a runoff period, and with all other factors remaining the same, a projected reservoir FC density of only 75/100 ml would be expected throughout the lake. Another factor to consider in estimating future impoundment bacterial quality is dieoff. Fecal coliform dieoff patterns have been established ------- 22 from considerable amounts of stream data. (9) Although the dieoff response may vary from stream to stream, some general relationships have been established. Figure 6 shows a general dieoff pattern for fecal coliform during summer months. The dieoff curve represents the percent of the initial density remaining with time. Applying the general dieoff pattern in Figure 6 to the maximum mean FC density measured at Site 8 indicates that a recreational criterion of 200/100 ml could easily be attained in those areas of the lake one day's flow time from the point of tributary discharge. This assumes no dilution and no additional indicator bacteria being added within the course of travel. Based on the dieoff pattern presented in Figure 6, much higher FC densities than those observed during this study would be required before violation of the recreational criterion would occur. This is especially true when the time of travel is 1.5 days or greater. From the dilution projections together with the knowledge that considerable bacterial dieoff will occur within the lake, it would appear that the bacterial quality within the Site 8 impoundment will be more than sufficient to support water contact activities. IMPOUNDMENT SITE 4 This site presents a rather unique situation in that during portions of the year there is no base flow in any of the streams within the drainage area. Another feature of this site is the ------- 100 0 bJ Q < UJ r lL. o o or UJ 0. CO < c/0 5 q: o 100 o o _i < o LJ U. I 0 _L _L 10 2 0 TIME OF TRAVEL (DAYS) 3 0 ------- 23 rapid runoff following rainfall. For these reasons, the Site 4 impoundment will be subjected to periodic influxes of runoff carry- ing high bacterial indicator levels. Applying the mixing equation previously used and substituting the mean FC densities measured at Site 4, the drainage area and pool volume, some estimates of future bacteriological quality are again made. The maximum and minimum FC densities measured were 8200 and 2800/100 ml. The drainage area for Site 4 is 9864 acres and the projected recreational pool volume is 6476 acre feet. As with Site 8, a mean runoff of 0.50 inches per month during the recreation season represents the incoming volume being discharged into the impoundment. A background FC density of 25/100 ml is assumed for the lake when completely filled. Using these figures and applying the maximum and minimum mean FC densities, the projected mean FC densities in the lake would be 490 and 180/100 ml, respectively. Although these projected densities are rough estimates, they do indicate the quality within this impound- ment could be marginal for water contact activities. Undoubtedly, there will be higher densities adjacent to tributaries. The apparent dramatic effect that rainfall in the Site 4 area has on both runoff and the high bacterial densities transported by this runoff makes projection of future bacteriological quality of the impoundment difficult. However, based on the high FC densities measured during the May 1972 study, indications are that the bacterial quality of the proposed impoundment would be marginal for water contact activities with all factors affecting bacterial quality considered. ------- 24 LIST OF REFERENCES 1.

The samples were collected in sterile glass containers and placed on ice until time of analysis. Most samples were analyzed within four hours of collection. Stream samples collected for the purpose of isolating Salmonella were obtained using a modification of the swab technique of Moore (10). Sanitary napkins (swabs) were folded, gauze ends tied together, and a length of heavy string attached. The swabs were then wrapped in kraft paper and sterilized. The sterile swabs were suspended beneath the water surface at selected sampling stations. After three to five days, the swabs were retrieved, placed in sterile plastic bags, and returned to the laboratory for analysis. BACTERIOLOGICAL EXAMINATION Fecal Coliform Enumeration The fecal coliform membrane filter procedure outlined in Standard Methods (11) was used. The procedure employs M-FC medium at an incubation temperature of 44„5 + 0.2°C (waterbath) for 24 hours. Fecal Streptococci Enumeration The membrane filter technique outlined in Standard Methods (11) was used. The method employs M-Enterococcus agar incubated at 35 + 0.5°C for 48+3 hours. ------- A-2 Salmonella Isolation and Identification Swabs used for isolation purposes were placed into wide-mouthed jars containing approximately 200 ml of 1 1/2 strength tetrathionate broth with brilliant green added. The inoculated enrichment was incubated from 24 to 48 hours at 41«50C according to the procedure of Spino (12). After either primary or sub-culture enrichment, an inoculum from each enrichment was streaked onto Xylose Lysine Desoxycholate Agar (XLD) and Hektoen Enteric Agar (HE) plates and incubated at 35° + 0.5°C for 18-24 hours. Suspected Salmonella colonies were picked from the respective plates and subjected to the identification scheme outlined in Table XI. The methods and media outlined in Table XI are described by Ewing (13), with the exception of the cytochrome oxidase method. Oxidase activity was determined using Pat'no-Tec-Coi^ reagent impregnated strips. Definitive serological identification of Salmonella isolates was made at the Southeast Water Laboratory. The methodology used was the standard serological procedures described by Edwards and Ewing (14). FLCfrJ DETERMINATION Streamflows were estimated, if possible, at each sampling station. Average cross-sectional measurements and average velocities were determined using a Pygmy current meter. Staff gages were installed for reference and velocities were measured each time the staff gage reading changed. 1/ Does not imply endorsement of the product. ------- Table XI IDENTIFICATION SCHEME FOR SALMONELLA SUSPECTS Suspect colony Lysine Iron Agar (LIA) Alkaline slant and alkaline or neutral butt with or without HgS Urease Production Acid slant and butt; Alkaline slant and acid butt-DISCARD Positive DISCARD Positive DISCARD Negative I Cytochrome Oxidase Negative I Lactose,Sodium Malonate; Indole Positive DISCARD Negative Lysine decarboxylase, Citrate, Motility, H2S Positive Negativ | DISCAr U U Poly C^Antisera Positive Negative I DISCARO Complete Serological Identification Confirmation of identification by National Center For Disease Control ------- APPENDIX B ------- Rainfall Data Date Rainfall (inches) Forest, Miss0—^ Mize , Mis s ^ White Oak, Miss.-I^ July 13, 1971 0.05 0 0 July 14, 1971 0 0.22 0 July 15, 1971 0 0 0 July 16, 1971 2.19 0 0 July 17, 1971 0 0 1.43 July 18, 1971 0 0 0 July 19, 1971 0 0 0 May 1, 1972 0 0.50 0 May 2, 1972 0.11 0.80 0.17 May 3, 1972 0 0 0.54 May 4, 1972 0 0 0 JL^National Oceanic and Atmospheric Administration weather stations nearest to the two study areas. ------- APPENDIX C ------- STORE.T RETRIEVAL DATE 72/06/02 274540 01 M-129-0 2 32 03 33.0 0B9 2a 5H.G LEAF R.-SHONGELO CREEK 28 MISSISSIPPI SOUTHEAST PASCAGOULA RIVER BASIN 1113S050 21 1 1204 3 0000 FEET OFPTh 0 0 0 10 0 0 0 M 31616 31679 DATE TIME DEPTH v) ATE-?
