* Because of lack of rainfall and near drought conditions in July, August and September causing erratic data, values should be considered very approximate only and should be applied with discretion. It is recommended that, where possible, high groundwater determinations where mottles are lacking should be postponed until the water table elevations are significantly higher and data is more consistent and reliable.
