v � Fnding Analysis potential was estimated under the ELF filter bed to ensure sufficient ment distance between the soil/effluent interface and the highest anticipated depth to ndwater. Calculated estimates indicate that an acceptable distance will be maintained. • During the course of the testing and calculations, it has been determined that the required 100%reserve areas for both the ELF and the VLF can be situated directly adjacent to both primary disposal areas. • Although ultimate wastewater flow volumes emanating from the completed project are unknown,particularly the proposed Office Building, average daily flow volumes were formulated using all available parameters acceptable to EHD. • The original study for this project conducted in February 2002, determined that a maximum of 300 people could occupy the subject property without exceeding the nitrate loading capacity of the property. Initial proposed occupancy is initially projected to be approximately one-tenth of maximum capacity. In the event that the population of the property approaches the maximum capacity and the property has not connected to public utilities, contingencies must be activated. This may include having to treat the effluent to a higher degree. In summary, the soils investigation has found the indigenous soils under the two proposed domestic wastewater disposal areas to contain differing loam soil types (i.e., sandy loam, silt loam, sandy clay loam, clay loam and a sand) and an apparent high denitrification potential within the soil column. Consequently, an advanced wastewater treatment system with a denitrification cycle, as referenced in the EHD Conditions of Approval - Item 3b. "NOTE,"may be considered duplicative based on the soil test results. The soil physical characteristics combined with the chemical characteristics contribute to the observed highly favorable permeability and denitrification potential. To take advantage of these favorable soil characteristics, a filter bed arrangement is proposed, with a pressure dose system to equally distribute the effluent over the disposal area and take advantage of the encountered favorable soil characteristics. Current nitrate impact to the water table under the existing facility was found to exceed the Maximum Contaminant Level (MCL) for nitrate under the proposed ELF. However, the nitrate concentration was nonexistent in the water table under the proposed WLF. Originally, there apparently were four domestic wells on the property. Two of these wells have been destroyed, one well apparently no longer exists or never existed, and one non-operational domestic well clearly remains on the property. Consequently, this non-operational well could not be sampled for analysis. EHD sampling guidelines state that domestic wells on adjoining or nearby properties from the property under examination are not be sampled and tested for said property. The non- operational well will either be abandoned, or officially taken out-of-service by Preston Pipelines in accordance with Item d. and e. The new domestic well for the project to be drilled near the south- central area of the property will be tested general minerals and nitrates in accordance with Item 3c. LL 2 Chesney Consulting
