Groundwater Benefits <br />27 <br />These protection . measures also help to maintain groundwater quantity and quality. By <br />encouraging infiltration, more water soaks into soils where it eventually becomes available for <br />potable use by installing wells. As stated above, when runoff infiltrates into the ground, natural <br />processes help to filter the water so that it is cleaner. During dry periods groundwater provides <br />base flow to streams. Thus, by encouraging more runoff to infiltrate the effects of drought on <br />streams and other surface waters can be reduced. <br />Conclusion <br />Protecting water supply sources within and downstream of Orange County has been a priority of <br />local staff and officials. Since land use does not remain static, periodic review of watershed <br />protection measures are warranted. As potential pollutant sources change, protection measures <br />may need to change. As described above, protection measures must be appropriately applied to <br />both large and small streams and land use draining to them. Without this level of planning, both <br />surface water and ground water quantity and quality cannot be maintained nor improved. <br />References <br />Alexander, et al, 2000.
