Feady m;daily that the EnviroServer unit will only process a maximum of 2,500 gallons teTherefore, although this daily volume may not occur, monitoring of the onasis is recommended after the entire project is completely developed to thallons daily flow is not exceeded. In addition, if it is anticipated that this may be exceeded, or if in the future it is unexpectedly exceeded, an additional ES25 unit must be installed. Provisions should be made for this. For example, an additional ES25 unit may have to be placed on the east side of the property. Consideration should be made to installing influent and effluent piping before paving. Use of Peat Under the Filter Bed In compliance with the requirement of EHD, biofibrous peat must be used at the soil/effluent inter- face to mitigate potential inadvertent release of nitrate laden effluent from the MicroSepTec system. Peat is partially decayed organic matter, predominately of plant origin. The peat filter treatment technology is founded on simple, passive biofiltration principles which include physical, chemical and biological interactions between the effluent and fibrous media. Physical interactions include filtration and adsorption, chemical means are by also adsorption and ion exchange, and biological actions are microbial and assimilation. Together,these interactions create a very high cation exchange capacity (CEC), creation of an acidic environment, and the antibiotic and disinfectant properties of the peat. These physicochemical properties of peat make it an effective biotreatment media. On a microscopic scale, the surface of the peat is composed of aerobic and facultative aerobic heterotrophic bacteria, along with higher life forms including protozoans, rotifers, nematodes, worms and insect larvae. Another beneficial capability of peat is to retain and hold water. This can induce a longer hydraulic residence time for biofilter treatment, along with creating anaerobic conditions at the soil/effluent interface, thus promoting favorable denitrification conditions. V. CONCLUSIONS AND RECOMMENDATIONS The soil physical characteristics under the proposed leachfield are comparatively permeable. This is the reason for the high nitrate concentrations observed in the groundwater under the property. These observed nitrate levels from the groundwater sample warrant the need for wastewater treatment to 1.) Alleviate nitrate loading and current impact, 2.)Produce an effluent of significantly lower nitrate concentration than conventional methods, and 3.) Create a dilution effect from wastewater recharge. In compliance with EHD's requirements, the MicroSepTec® ES-25 systems must produce an effluent quality continually consisting of a nitrate-nitrogen concentration of 10 ppm NO3 N or lower.
