O30 Princeton Hydro Report Dated 9 3 25

3/31/25, 1:09 PM Official Series Description - HALEDON Series and from moderately acid to neutral in the lower part of the C horizon. The O horizon, where present, has hue of 7.5YR or 10YR, value of 2, and chroma of 1 or 2. The in lieu texture is commonly highly decomposed plant material but the range includes slightly to highly decomposed plant material. The Ap horizon has hue of 7.5YR to 2.5Y, value of 3 or 4, and chroma of 2 to 4. Value is 6 or more when dry. Some pedons have an A horizon up to 13 cm thick. It has hue of 7.5YR to 2.5Y, value of 2 or 3, and chroma of 1 or 2. Texture is loam or silt loam in the fine-earth fraction. Some pedons have a BA horizon. It has hue of 7.5YR or 10YR, value and chroma of 4 to 6. Texture has the same range as the A horizon. The Bt horizon has hue of SYR to 10YR and value of 4 to 8. Chroma ranges from 3 to 6 in the upper part of the B and from 1 to 6 in the lower part. Redoximorphic features are few to common in the upper part and range to many in the lower part. Low chroma redoximorphic features are within the top 25 cm of the Bt horizon. Texture is loam, silt loam, or fine sandy loam in the fine-earth fraction. The Bx or Btx horizon has hue of 5YR to 10YR, value of 4 to 6, and chroma of 2 to 6, or it is mottled or variegated with these and other colors. Black stains are in most pedons. Texture is sandy loam, fine sandy loam, or loam in the fine-earth fraction. Structure is weak or moderate, thick or very thick platy or the horizons are massive. Consistence is firm or very firm. The Cd horizon, where present, has hue of 2.5YR to 2.5Y, value of 3 to 6, and chroma of 2 to 6. High and low chroma redoximorphic features and black stains are in most pedons. Texture ranges from loam to sandy loam in the fine-earth fraction. COMPETING SERIES: There are no other series in the same family. Related soils in other families are the Boonton, Califon, Hibernia, Rockaway, Wethersfield and Wurtsboro soils. Boonton and Rockaway soils do not have low chroma tedoximorphic features in the upper 10 inches of the argillic horizon. Califon and Hibernia soils have less then 35 percent base saturation. Wethersfield and Wurtsboro soils do not have argillic horizons. GEOGRAPHIC SETTING: Haledon soils are at the base of steeper sloping uplands and in shallow drainageways. Slope ranges from 0 to 15 percent. The soils developed in coarse

not have argillic horizons. GEOGRAPHIC SETTING: Haledon soils are at the base of steeper sloping uplands and in shallow drainageways. Slope ranges from 0 to 15 percent. The soils developed in coarse textured glacial till composed primarily of basalt, red sandstone and shale, and granitic gneiss with lesser amounts of quartzite and gray sandstone and shale. The mean annual precipitation ranges from 102 to 122 cm. The mean annual temperature commonly ranges from 7 to 10 degrees C but the range includes up to 13 degrees C in or near urban areas. The frost-free days range from 140 to 160 days. GEOGRAPHICALLY ASSOCIATED SOILS: These are the Boonton, Rockaway and the Holyoke soils. Boonton and Rockaway soils usually are in higher positions in the landscape. Holyoke soils are in a higher position in the landscape and are shallow to bedrock. DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. Surface runoff is medium to very high. Saturated hydraulic conductivity is moderately high or high above the fragipan and very slow or slow in in the fragipan and densic materials. A perched high water table is within 30 cm of the surface in the late winter and early spring of most years, and following periods of extended rainfall. Lateral seepage is common, particularly at slope breaks. USE AND VEGETATION: Most areas are wooded or in idle fields. Much of this soil is used for housing or urban development. Vegetation is largely forest dominated by oak and maple with some birch and ash. DISTRIBUTION AND EXTENT: Northeastern New Jersey and New York City metropolitan area; MLRA 144A. The series is of moderate extent. MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts SERIES ESTABLISHED: Morris County, New Jersey, 1971. REMARKS: Diagnostic horizons and other features recognized in this pedon include: 1. Ochric epipedon - the zone from 0 to 20 cm (Ap horizon). 2. Argillic horizon - the zone from 20 to 76 cm (Bt horizon). 3. Fragipan - the very firm, brittle zone from 76 to 114. cm (Bx horizon). https://soilseries.sc.egov.usda.gov/OSD_Docs/H/HALEDON. html 23
