Dear Mr. Warner: As requested, on October 4, 1996 I visited the above referenced property in order to render an opinion as to whether or not the soil colors observed within a proposed on- site sewage disposal area are as a result of a high water table. As will be explained below, it is my opinion that these colors are not a result of a seasonal high water table, but are due to the infiltration of water through stratified deposits of varying textures. The site is located on a small kame terrace, with a large till hillside to the west. The soils on this kame terrace consist of stratified layers of well-sorted glaciofluvial deposits. As observed during our site visit, sandy material extends from the surface to a depth of more than nine feet. The soils were observed to contain areas of higher and lower chroma colors. Although these colors were originally described as mottles, upon close inspection it was observed that the colors are found in narrow horizontal bands, which are actually small sub- horizons. These sub-horizons range in texture from very fine sand to gravelly coarse sand, and the layers are too numerous to describe. Many of these stratified layers are less than one-quarter inch in thickness; in places, the layers are discontinuous, probably due to slumping of the terrace after ice melt. The colors were consistent within each horizon; that is, there was no mottling of colors within a horizon of uniform texture. However, there were "rust lines" of bright color which were observed in many locations where a finer textured layer was above a coarser layer. As we discussed at the site, horizontal rings of oxidated iron, commonly called "rust lines," are frequently found in stratified sand and gravel deposits which are never saturated with water. This is because the movement of water within a stratified deposit of sands and gravels is not uniform. As the water infiltrates downward, it will pause briefly when passing from a finer textured stratum into a coarser stratum. This phenomenon is due to the contrast in size between the smaller pores in the overlying s ER 10 0 / / Mr. Gary Warner - 2 October 7, 1996 horizon and the large pores in the underlying stratum. In this situation, the adhesion of the water to the soil particles and the cohesion of the water particles to each other is greater than the gravitational pull into the large underlying pores. As a result, water pauses in the small pores until sufficient pressure builds up, upon which the water continues its downward movement into the coarse stratum. As a result of this pause in the downward motion of the water, iron within the water will often precipitate out, forming a distinct horizontal band or "rust line." In order to be certain that a rust line in a stratified deposit is the result of the downward movement of water, and not a high water table, two general parameters should be met. First, the rust lines should be found only between an overlying finer stratum and an underlying coarse stratum. Second, there should be no mottling within the underlying stratum. Both of these parameters are met on this site. On a practical note, it is clear that the water table could never reach the level of these rust lines given the depth of the coarse textured soils and the slopes below the site. In summary, it is my opinion that the rust lines in the observed pits are a result of the downward motion of water through stratified deposits of varying textures, and not as a result of a high water table. Please feel free to contact me if you have any additional questions regarding these soils. Sincerely, Valley Environmental Services • Ward W. Smith, P.W.S.
