Sampling program to determine if pesticides are present in ground water, in accordance with Wyoming's Generic State Management Plan for Pesticides in Ground Water (SMP).
The groundwater component of streamflow is important because it is indicative of the sustained flow of a stream during dry periods, is often of better quality, and has a smaller range of temperatures, than surface contributions to streamflow.
Shallow groundwater has good quality, but salinity measured in wells suggests the thin lens of freshwater under the coastal plain will be vulnerable to saltwater intrusion as a consequence of pumping.
Lower precipitation and recharge, with deeper groundwater levels, suggest this basin will be less susceptible to contamination than others nearby, but may be susceptible to saltwater intrusion brought on by well pumping.
Annual peak flows have increased at most rivers in Maine during the last century. What effect does this have on computed peak flows, such as the 100-year flows, that are used for designing bridges and other structures?
