AbstractGround‐water quantity data were collected at a 22‐acre farm site near Churchtown, Pennsylvania, to determine if terracing changed the quantity of water recharging the aquifer. Double‐mass comparisons of water‐level data from six wells at the site were used to determine that the construction and operation of six pipe‐outlet terraces caused no statistically significant changes in the quantity of recharge to the carbonate aquifer. Analyses of water‐table altitude data from site wells indicate that terracing did not change mean annual water‐table altitude
