Despite multiple layers of preventative measures now in place to prevent water treatment <br />plant overflows, it will be best to conduct future remedial activities involving excavation of <br />alluvial fill materials during the months of August and September, and to complete such <br />activities prior to mid-October when Ralston Creek historically begins flowing again <br />adjacent to the alluvial fill and recharges groundwater tables. This will reduce the potential <br />for having to manage, store or treat large amounts of groundwater which could contain <br />sediment and may exceed flow capacity limitations or cause related problems. <br />Aside from expectations that the problematic circumstances described above have been <br />effectively mitigated, there is still the potential for periodic operational problems that can be <br />expected with any mechanical/electrical system. For this reason, a daily inspection check list <br />has been developed for site personnel to perform.
