This letter is to inform you of the positive experience I had using Proactive Environmental Products™ Mini-Monsoon® groundwater pump we recently purchased.
Our client has a fuel terminal in Southern Minnesota that has groundwater impacts for at least 20 years. The geology at the site is fractured bedrocks, and we have a series of shallow bedrock monitoring and recovery wells that range in depth from approximately 70 to 90 feet below ground surface (bgs). Groundwater is encountered at approximately 50-60 feet bgs.
The casing/borehole diameters of the wells range from 4 to 8 inches.
We have a large volume of water to remove from each well; therefore, we have attempted to find an efficient yet low maintenance of purging the wells. I believe that we have found the answer in the Mini-Monsoon®. The Mini-Monsoon® allows us to purge deep wells at a faster pace than hand bailing, without the worries of purging the wells dry, like we have had with other methods such as the Grundfos pump. The Mini-Monsoon® pumps at a rate that does not affect draw down in nearby wells, yet saves us time and our client money!
I believe you have a superior products and we look forward to using the Mini-Monsoon® on a variety of projects!
