If the chemical option is needed, Weber Water would use 770 <br />gallons of Water Solve BC with 30-35% active peroxide equivalent to 5% of the well volume. <br />Weber Water wiff ,nix chemical above ground and inject through a dual swab zone tool in 20-foot sections throughout <br />the well. The well will then be brushed at a rate of 1 minute per foot. Weber Water will allow 48 hours of contact time <br />followed by a post chemical video. <br />Regards, <br />Jose Villanueva <br />(951) 215-5481 <br />weberwaterresDurces.com <br />P: 909.383.3837 t F: 909.386.1259 <br />2073 Rallroad SfraGf, Corona, CA 92890 <br />
