A summary of the inspection is below. Septic Tank Condition 1. Pumpout not n eded at this time. The septic system is non-co pliant due to a lack of a three foot separation distance between the bottom of the drainfield to the seas° ally high watertable. The three foot requirement is a State Code,not a City Code. A soil boring was co ducted to determine the depth of the seasonally watertable. The septic system must be replaced by ecember 31,2010. Enclosed is a list of state li ensed septic contractors who work in Orono on a regular basis. Also enclosed is a fact sheet expl ' g how a septic system functions properly. Finally, an as-built drawing is enclosed that shows the ap roximate location of the septic system. If you have any questions regarding this report, please contact me at the City Offices at 249-4600.

Professional Site Evaluations 4810 West Medicine Lake Dr. 612-553-1615 Plymouth, MN 55442 SITE EVALUATION A site evaluation is a p ocess whereby a proposed lot of land is assayed for suitability to accept and treat domestic generated sewage wastes. In the pest,too often this process was never applied and subsequently the homeowner was burdened with a in- effective sewer system,wet basement,or crumbling foundations,etc.A site evaluation includes information on soil suitability for proposed lot impro ements, surface water drainage routes, water table establisment,and topography. Recommendations are given as to sewer sy tem design and placement, house siting,and drainage routing. Many problems we've since encountered could have been elimin•ted at this planning stage. THE ELEC RO-OSMOSIS CONCEPT FOR ON-SITE DISPOSAL SYSTEMS -CLAY SOILS. A description of the el tro-osmosis method is that by burying dissimilar materials on opposite ideds of a drainfield an electric potential will be devlo'ed in the soil water complex.This will occur without the use of any otuside current,wiring or power source. The ground between the fine grains is made up of three layers,an uncharged inner core,a negatively charge layer fixed to the soil grains, and a positively charged intermediate layer between the fixed layer and inner core.Normally the positive and neg- ative water layers adh re to each other,but when an electric potential is applied between nearby electrodes the positive layer will flow towards the egative electrode,dragging the uncharged water core with it. The percolation effect brought by the release of hydrogen and other gases upwardly through the soil improves the soils per- meability and friabilit . In case of fine grain s ils, which are normally incapable of being drained, or if drainable,only with great difficulty by usual methods, the phenom na of electro-osmosis is brought about in the capiliaries of the soil. If the electrical current is flowing in the proper direction, he water particles are transported effectively through the pores of the soil in the direction of the lines of the electrical field tO the cathode.As a result of this process,the increased movement of the underground water so brought about is far greater than that imposed by the natural hydraulic gradient. Electro-Osmosis utiliz s the natural electrical eneragy created by the saturated clay particles within the soil.The anode attracts negative charge ions uch as oxygen, phosphates and nitrates. The positive charged ions or hydrogen is attracted to the cathode, allowing the removal of the outer water layer from the clay particles. As this outer water layer is removed it is re- placed by free water om the capillary waters,thereby producing water movement toward the cathode. Hydrogen being a ca- tion is attracted to thle cathode. Oxygen being an anion is attracted to the anode thus helping to maintain aerobic conditions in the soil. WISCONSIN TYPE PRESSURIZED MOUNDS A pressurized sewage treatment mound is a specialized sewage treatment unit applicable to high water table areas and soil types too permeable or too impermeable to provide adequate treatment/disposal of sewage. Typical applications would be coarse sandy soils, cl.y soils and/or lakeshore property. The construction of a mound requires various types of materials be brought onto the site in order to build up a sewage effluent treatment area large enough to accomodate projected daily water use. • ENVIRONMENTAL CONSULTING ASSOCIATES 5522 ATLAS STREET LOS ANGELES.

Coolbroth, founding President of the National On-S' te Sewage Treatment Association , Inc. , who operates Cool•roth-Sitton Septic Tanks , Inc. at Minneapolis has made over 40 successful installations in Minnesota and more in near by states . There are now in the United States a total of o er 180 successful systems installed under standards and licensing agreement with the patent holder. Defi ition, Theor and Back•round of Process The International Dictionary of Physics and Ele tronics says : "Electro-osmosis . . . : The movement of liq id with respect to a fixed solid . . . as a result of an pplied electric field. " McGraw Hills ' Encyclopedia of Science and Technology says : (A) Electro-osmosis was first observed by F. Reuss in 1809 . This investigator pushed two vertical glass cylinders into a mass of wet clay, filled the cylinders with water, and inserted metal electrodes . When an electrical potential was applied, the level of water rose at the negative , but fell at the positive pole to which the suspended clay particles were attracted. The results were in accord with the view that the clay particles were negative with respect to the water. Electro-osmosis has been applied to the removal of water from peat and moist clay. (B) Electro-osmotic Dewatering: A method of drying out an excavated area, used to increase the strength of the ground and permit tolerable excavation slopes . This 1 2 • i . achieved by forcing the flow of ground water to d ainage wells by the application of a direct current b- tween electrodes inserted in the ground. Electro- o-mosis dewatering is confined to fine grained soils , s ch as silts and clays . The book, Applied Clay Minerology (1962) by Ralph E . Grim, then Research Professor of Geology of the University of Illinois , noted that the water in clay soils "is present in two states : (1) oriented water surrounding the clay miner: 1 particles , and (2) non-oriented liquid in the inter.titial pores . A 1960 translation from the Russian literature by the I linois Geological Society quotes B.A. Nikolaer' s paper on "P. enomena Originating in Ground While Sinking Piles by Elect o-osmosis . " The author says , "Most clayey soils are comply electrical systems . " He and other authors note that the s ' rface of fine soils commonly carry a negative charge . Surro nding the particle surface there is commonly found a very hin layer of bound water with a positive charge . Application to the soil of a direct current electrical potential causes the positively charged , electrically bound water to be released and drawn through the pores and capil aries to the cathode . That process produces the commo ly achieved soil stabilization by electro-osmosis and also roduces the desired effect for sewage electro-osmesis . Nikolaer also said that besides electro-osmosis , direc current produces hydrolysis of water and other physi o chemical processes . Gaseous hydrogen (H.)) is evolved at th cathode. (This is regularly observed at the cathode vents of sewage electro-osmosis systems . ) He further said, "At t e anode, oxygen is evolved by hydrolysis . " (This may p rtly explain why when electro-osmosis is used to corre t an existing system which failed, the black sulphur slime,'observed when the failed system is first examined, quick y disappears . ) It is assumed that the oxygen released at th anode travels with the water and helps oxidize the anaer bic (without oxygen) microbiological slimes. Pre-Treatment As with all satisfactory soil absorption systems , electbo-osmosis systems include a means for removing subst-ntial amounts of the suspended and settleable solids from .he waste . For economy, simplicity and efficiency , this ' s usually a septic tank . 3 Dosing The liquid from the septic tank can flow by gravity to th- seepage trench system but it is commonly discharged from a chamber arranged for intermittent pumping. A pumped discharge has advantages , especially on level ground where it is desired to keep the system as shallow as practical to obtain maximum advantage of irrigation by upward flow of water by capillary action. Leachin. S stem As with most soil absorption systems , the effluent from the treatment tank flows into a seepage trench system. The trenches are usually 2 feet wide and a total of 3-1/2 to 4 feet deep. Perforated drain pipes discharge the liquid into a bed of rock which extends to above and 2-1/2 to 3 feet below the pipe . The lines are laid "serially, " that is , one continuous line . For a home, the length varies according to site conditions but is seldom over a total of 170 feet long (a considerably shorter trench system than for a conventional system) . Electro-Osmosis System The unique feature of the electro-osmosis system is . that the direct electric current is provided and maintained by literally creating a long-life dry cell battery in the soil . At various points along and immediately next to the seepage trenchs and on their down-slope sides (away from the s ptic tank) , cells are constructed (usually 3 feet wide , sixfe t long and 6 feet deep) . On the up-slope and several feet from the seepage trenches , are constructed one or more 6 foot deep cells filled with coke and having graphite cores and having vertical pipes which serve as vents and inspection openings. (Cathodes) Downslope cells (anodes) are filled with a special mineralized rock. The seepage trenches are built so one section must fill to the level of the distribution pipe before liquid can enter the next section. This facilitates lateral movement of the liquid. It also provides a " factor of safety" since it is seldom that all sections of the system are in actual use . 4 S•eci=1 Studies, Demonstrations and Observations The most important observation is that the 180 existCng systems have functioned successfully for up to 7 years and there is no evidence of "progressive failure . " The Appendix contains samples of letters from property owner who are pleased with their systems and from regul tory officials who will accept the systems where conve tional systems are not allowed. Some test programs are "too good to be true , " such as a test installation at a Minnesota farm home in which over 50 ,000 gallons of septic tank effluent have been disch.:rged over an 18 month period into a system built like a non seeping evapo-transpiration bed, but the drain lines are 1.;id in compacted clay. (Details available. ) Detailed measurement of water levels in various • parts of several systems have been made during various seaso s and laboratory analyses have been made of liquid which reached the cathode. (See Appendix. ) Mr. Nix Anderson, who is in charge of the regulatory progr-m of the Casper-Natrona County, Wyoming, and Mr. Frank Coolbioth have made illustrated presentations at meetings of th= National Environmental Health Association showing how syste s are planned, installed and observed, and explaining . how e ectro-osmosis systems functioned well in soils not suita•le for conventional systems. Mr. David D. Effert, in 1977 , completed his Master' s Thesi- on "Performance of Alternate Wastewater Treatment Syste s . " This included a 17 to 20 month test and observation to co pare the "Wisconsin Mounds , " an aerobic unit and elect o-osmosis in relatively tight soils. During the study, 144 , 530 gallons of septic tank effluent at a home were applied to the first section of a serially installed trench of the electro-osmosis system. Only 9% passed on to the second section and none to succeeding secti.ns . The thesis noted the system size (built according to st-ndard electro-osmosis practice) " could be decreased with o harmful effect . " The report said, "The only system which had no problems and caused the homeowner no inconv-nience was the sewage osmosis system . . . . Each of the of er systems failed at least once during the study. " Mr. Coolbroth ' s records show that he never installs more ti an 170 lineal feet of 2 foot wide seepage trench 5 (com only no more than 120 lineal feet) and that even in the •st unfavorable , wet weather, only a portion of the trenc system becomes filled. For a soil requiring 60 minut-s to percolate one inch and a 4 bedroom home 640 lineal feet of 2 foot wide trench would be required to satisfy the anual of Septic Tank Practice . His records show that in ma y cases the cost of electro-osmosis is only slightly more than a conventional system. Mr. Nix Anderson reported installations in Wyoming soil hich had a percolation rate of hours per inch and are working perfectly. Illinois officials reported favorably on the first sys ten in that state. Some experiences seem too good to be true. Mr. Coolbroth made a Michigan installation at a site with a percolation rate of 2016 minutes per inch. Six weeks after • the s wage electro-osmosis system was installed he re-tested at thesame location and found the rate had increased to 30 mi utes per inch. • At a California state park, Mr. Jim Peterson made an installation after a conventional system failed. After 10 months the system is working perfectly and only about one-fourth of the installed seepage trench is actually in use . . To answer the question of whether the system will work in soils other than clay , Mr. Coolbroth made successful installations 3 years ago in a fine sand that had a percolation rate of 60 minutes per inch where the original , conventional system had failed. He installed only two forty foot seepage trenches . They have never found water in the second trench. Electrical Phenomenon f Mr. Coolbroth is learning much by his use of stainless steel probes which he drives into the soil and from which he meas res the magnitude of electrical potential and the dire tion of current flow. He also measures the soil' s resistivity to current flow. Study of natural potentials ?2.1,4 current aids in ..4-=-=:' ,77n ,-,f the system. Measurements of electrical _'psi_T v (",r'Y- closely with measurements of percolation _atfis , 6 Conc usions There is now ample evidence from experience in a wide variety of locations to conclude that: '1 . Sewage electro- smosis systems will function well in siils with percolation rates well above normally allo. able limits . 2 . The system minimizes plugging of the trench- soil interface by a combination of alternate wetting and drying and probably by oxygen generated by hydrolysis . 1 3 . The electrical potential appears to more-or-less perm nently increase the permeability of soils. 4 . The system requires a minimum amount of main enance beyond the regular and proper maintenance of the re-treatment system. Limi ations The system is not intended for installation where prol nged high groundwater levels will cause flooding of the seepage trenches . • Special care is required in designing systems for relatively steep side-hills , particularly with respect to place ent of the anodes and cathodes . Site evaluations , including the direction and magnitude of existing natural electrical potential and soil electrical conductivity must be made by an experienced installer.

Launspach has installed one of the new septic systems which has lime and charcoal and generates an electric charge apparently hydrolizing the water to hydrogen oxygen . We had this system installed in replacement of a standard leach field which was approximately half again the size that the County Health Agent felt should be needed for our house . The ground however turned out to be even less absorbent than perk tests • had previously demonstrated . The conventional leach field Alsm was a complete failure being like a sea of mud . We ha e not changed the water in our house since the installa- tion f this new system and we are very pleased with it . Mr . Launs a':h and the installer , Carol Sparger . have repeatedly check d the water level in this system and found there to be pract ' cally none . I am ery pleased,'with this system and it looks like it is proha ' ly a system• of the future with probably little grolind cunta ination involved . • If th re are any further questions , I would be pleased to discus this system at any time .

Last summer our four year old sewer system was seeping from the end of our lines. The village of Independance came to our house and informed us that we would of course have to revamp in some way to have a workable system. It was even more important for us to have a, workable system as we are living on the bank of Lake Sarah and pollution to the lake is then considered . At first we ere beside ourselves as to what to do . We called our origional sewer man , Bobby Schmitt and he informed us on his first f visit to check how bad how problem was , about a new system that would work in an area of ground that would not even pass a perculator test . Cur ground is solid clay and thus drainage is bad . He told us he would find out more about this system and contact us then . meanwhile th village of Independance kept us under constant ob- servance . Bobby Schmitt installed your sewage system in November of 1974 . We have since had not one bit of trouble with our drainfield or system. de have lived with our six person family and lots of relatives as we did when we had a city system. We shower when we want, flu is toilets when we want, use our automatic washing machine as ch as we want and do not worry a bit about it . We again have p ace of mind that all is in workable order . This of course if great ! ! One week ago Mr. Frank Coolbroth and Bobby Schmitt came out to inspect our system as to workabity and gave it a stamp of 100% workable system. I want all to know in this day of pollution that I would shout nut to the world " lease listen to this great new idea" Thankyou for sharing your great system with us . . .

Minnesota July 17, 1975 Mr. Frank Coo l b oth Coolbroth-Sitto Septic Tanks,Inc. 4810 West Me di c ne Lake Drive Plymouth, MN. 5442 Dear Frank: . For some t me I have wanted to express our appreciation for a sewage system that has given peace of mind since moving into our new home last November. One of my jor concerns was the very heavy and compacted clay soil that we have or. cur lot and in this area. Knowing- that a number of our neighbors have had problems wi h other systems than the Osmosis type, we wanted a system that would function yell and without problems until sewer lines come into this area. Our percolation tests substantiated a potential problem. :lith a family of five, there was no qu stion that we needed a yell performing and trouble free system. And I admit I h d some reservations that the Osmosis system would meet the specifications hat you had claimed. even with cavy snows this past winter and heavy rains this spring thru June, we have h.d no problems. :although we were careful in the amount of water used, :seasurer:e is at the inspection points this spring indicated that only one- half of the sys em was bin used. Later in June and with deliberate increased use of water, w- were amazed to find that we were operatin7 only on one-fourth of the system. Therefore, we have only used one-half of the system at the cost which indicates the potential that still exists if we ever need it. I'm con- • vinced that eve with more use of water, we would not use the full system. This is reassuring a ;d is a relief to know that we have a system that is more than adequate and on that fully meets our needs and the expectations stated by you.
