As we enter the peak water-use months of summer and early fall, it’s worth taking a moment to assess the value of this resource that is often taken for granted. After all, water makes everything possible in this semi-arid region, from baseball fields and microbrews to biotech and backyard gardens. We recently asked 1,000 county residents what they thought about the value of water as part of the San Diego County Water Authority’s long-running series of public opinion polls. On an unaided basis, two-thirds of respondents (67 percent) said they considered water a good or excellent value.
