Abstract

The Pineland Sands area consists of about 770 square miles of surficial glacial outwash which is undergoing increasing ground-water development for irrigation. The aquifer material is commonly very fine sand to fine gravel. Grain size and thickness generally increase from south to north. Test augering and pumping tests indicate that well yields exceeding 1,000 gallons per minute can be expected in about 15 percent of the study area , mostly in the northern part. Water in the aquifer is of the calcium bicarbonate type and is chemically suitable for irrigation. The average water budget for the aquifer involves inflow and outflow of about 295 cubic feet per second. Most recharge to the aquifer is directly from precipitation and most discharge is base flow to streams and lakes. Mathematical-modeling results show that much of the aquifer system can safely support long-term, large-scale withdrawals. Most pumpage would be derived from intercepted base flow to streams.
