Abstract

The groundwater observation well network consists of thirteen wells, MTOW-01 through MTOW-13 (figure 1). MTOW-01, located near Snicarte, Illinois, is an inactive, large diameter, hand-dug domestic well that has been monitored by the ISWS since 1958. This well is equipped with a Stevens, Type F water-level recorder that produces a continuous record of the groundwater level on a 32-day paper chart. The remaining observation wells are drilled wells between 2 and 6 inches in diameter. With the exception of MTOW-05 and MTOW-09, these wells are equipped with pressure transducers that electronically log the groundwater level data. In Year 15, a new well was drilled to replace MTOW-1. This new well, named Snicarte #2, will eventually take the place of the original well (MTOW-01 or Snicarte #1) within the monitoring well network. The two wells are still being observed jointly so that their water level data can be correlated. The new well was originally equipped with the same type of Stevens recorder as the original well, but has since been converted to digital data collection. This digital data collection system is outfitted with telemetry which allows access to the data at the ISWS office via a cell phone modem. The final correlation between data from the two Snicarte wells will occur during Year 18. In accordance with our agreement, each well, with the exception of MTOW-05 and MTOW-09, is visited by ISWS personnel during the first few days of the month during irrigation season and approximately bi-monthly during the non-irrigated portion of the year. MTOW-01 is visited monthly because of its inclusion in the Shallow Groundwater Well Network of the ISWS Water and Atmospheric Resources Monitoring (WARM) Program. When the final correlation between Snicarte #1 and Snicarte #2 has taken place, Snicarte #1 will no longer be visited. Snicarte # 2 will take its place within the monitoring well network and will be visited only a few times per year.
