Water levels (30-day moving averages) at five of these wells are within their normal range for May 12; water levels at the remaining three wells are below their normal range for May 12. Water levels at the Cumberland Co., New Jersey coastal plain observation well are currently just slightly below their normal range. Water levels at the New Castle Co., Delaware coastal plain observation well were within their normal range on April 15, when last observed. Attached are graphical representations of the average water level in the eight upland monitor wells and in each of the two coastal plain monitor wells (New Castle Co. and Cumberland Co.) over the last 43 months.

During April, the location of the seven-day average of the 250-ppm isochlor (salt line) ranged from river mile 60 to 68. The normal location of the salt line during April is river mile 61, a location which is eight miles downstream of the Delaware Memorial Bridge.

As of May 12 (the most recent date for available data), the salt line was located at river mile 70. This location is six miles upstream of the normal location for May.
