No violations were received during this reporting period.
D. Source Water Total Dissolved Solids (TDS)
Veolia has a goal of maintaining an acceptable blended TDS level between all its sources. This goal is achieved by shifting production to or fro m the lowest TDS wells or purchased low TDS water while adhering to the overall water supply strategy and meeting system demands. The TDS was 2 53 mg/L for the month of June as compared to 2 23 mg/L in May . The TDS levels are below the secondary maximum contaminant level requirements.

VI. WATER QUALITY COMPLAINTS
No complaints were received during this reporting period.
VII. OPERATIONS UPDATE
The overall operational strategy is to meet the daily water demand. The City of Rialto water system has six operational wells, one of which is owned by the County of San Bernardino and operated by Veolia; Oliver P. Roemer Treatment Plant (OPRTP), which is jointly owned by the City (25%) and West Valley Water District (WVWD); purchased water through the Baseline Feeder (BLF) system from San Bernardino Valley Municipal Water District (SBVMWD); and, if required to meet demand, additional water can be supplied by the City of San Bernardino (CSB) through the BLF for emergency supply only with no guarantee of actual delivery. Water produced from City Well 4A discharges into the BLF and its production is included in deliveries from that shared transmission line when City Well 4A is in service.
12 The overall pumping strategy is based on adjudicated rights, well availability, remediation requirements, and quality of source, cost to operate, and varying weather conditions. TDS effluent concentrations for the City of Ria lto WWTP are taken into consideration when operating the facilities and water sources.
A. Operational Wells
EW-1 well was out of service due to pump issues.
B. Valve Activity
On the basis of information collected in 2019, Veolia now has a baseline assessment of all valves and has initiated a new cycle of valve exercising . 48 valves were exercised in the month of June.
