Soil Pits Site Descriptions & Analyses
CH-014 (Basin 35)
- CH-014 was collected from a riverbank. The O/A horizon is an organic-rich silt loam about 15cm deep. The B1 horizon (15-35cm) is very clayey, possesses a weak structure, and is between 30-40% gravel. The B2 horizon is 50-60% gravel. The flatland approaching the bank appears to be a grassy field with a few scattered small trees. The field slopes sharply towards the bank. The levels of 137Cs and 210Pbex exhibit fairly typical exponential-type decay with depth. The amount of 210Pbex decreases more quickly than the amount of 137Cs.
CH-015 (Basin 35)
- The soil comprising CH-015 is a uniform, coffee-brown color throughout the column. The O/A horizon is a dark clay loam that is high in organics and is about 35cm thick. The B horizon is gravelly silt clay with 40-50% gravel and weak structure. This soil pit is located in a farm field. The amount of 137Cs and 210Pbex both increase between the 0-5cm section and the 5-10cm section, and drop off dramatically with increased depth. This pattern suggests that this area has experienced a change in erosion rates.
