Title
Resolution to Approve Bulk Chemical Purchases for Sodium Hypochlorite (JCI Jones - approximately $119,900.00/year), Hydrofluosilicic Acid (Univar- approximately $22,304.00/year), Pebble Quicklime (Graymont - approximately $715,000.00/year) and Ferric Chloride (PVS Technologies - approximately $50,320.00/year) for the Water and Wastewater Treatment Plants (estimated $901,428.00/year)
Memorandum
Your approval is requested to authorize the purchase of bulk chemicals - sodium hypochlorite, hydrofluosilicic acid, pebble quicklime, and ferric chloride - used in treatment processes at the water and wastewater treatment plants (WTP and WWTP).

In 2019, bids were obtained through the Mid-Michigan Drinking Water Consortium Bulk Chemicals Bid. The Consortium was formed in 2014 by mid-Michigan area utilities that soften drinking water with quicklime, to address chemical supply quality, competitive pricing, and residual disposal.

Consortium members include: Lansing Board of Water and Light; City of Battle Creek; City of Jackson; City of Howell; City of Ann Arbor; City of Fenton; East Lansing Meridian Water & Sewer Authority; Plainfield Township; City of Owosso; Marion-Howell-Osceola- Genoa Water Authority; and Tri-County Regional Planning Commission.

Sodium Hypochlorite
The WTP uses sodium hypochlorite to maintain disinfection of drinking water in the distribution system. The estimated cost of this chemical for FY20 is $111,900.00/year for approximately 150,000 gallons.

Sodium Hypochlorite Bids were as follows:

The Centers for Disease Control has established that 0.7 mg/L of fluoride in drinking water is safe, healthy, and effective for preventing tooth decay. The City's source water contains approximately 0.3 mg/L of fluoride. The City uses hydrofluosilicic acid to adjust the fluoride level to meet Center for Disease Control's recommendation.
