Additional requirements include specific gravity of 1.29 +/- 0.02, pH of 7.0 to 9.0 for a 5% solution, and bulk density of 10.6 to 10.9 lb./gal. Bidding shall be submitted in U.S. dollars per gallon rounded to two decimal places, with pricing truncated if it exceeds two decimal places. Vendors must deliver by truck in bulk containers within 72 hours of order placement or per a mutually agreed schedule and must submit a certified analysis including MgCl2 content. Payment is based on gallons received at each location, with the certified analysis subject to review by GCDWR.
