We used Cyper TC under our foundation when we built our house in 2005. We ran the sump pump water around a pond in back of our house to avoid any contamination at the time, but are now wondering how long we need to worry about this. Your info says it's effective for 5-7 years so is this the length of time to insure none of the material gets in pond. FYI, we do have the pond stocked and fish from it.
Typically, termiticides like the Cyper TC, have very low solubility in water and they are unlikely to leach out of the treated soil when rainfall or irrigation later contacts said soil. The molecules of the active ingredient tend to bind tightly to the soil particles, and unless the soil itself moves from erosion the Cyper TC will stay put. Cyper TC does not go back into solution when water passes through the treated soil.
