Water quality sondes, sensors (probes) and accessories are needed to support the District’s continuous water quality monitoring and ambient water quality monitoring. YSI (EXO) products have been integrated into the Bureau of Water Resource Information’s monitoring program and have proven to be reliable and an asset to the program. The District anticipates issuing a Blanket Purchase Order to the supplier who provides the lowest total cost of the items in Exhibit 2 – Unit Price List. The District will order the equipment on an as needed basis and makes no guarantee of the amount to be purchased. The Unit Prices provided will be firm through September 30, 2024.
