STATE SPENDING AS SHARE OF ECONOMY

CA FWD: CALIFORNIA FORWARD
There is no limit to the challenges on the horizon. In the next 30 years, California’s population is expected to grow to 50 million people—the equivalent of adding another city of Los Angeles and San Diego. As income inequality expands, new approaches must be developed to prepare this next generation of Californians to contribute to an ever-changing global economy. With the climate changing, natural resources must be managed more responsibly. Bigger cities need less traffic. Communities need more reliable sources of water. Regions need new avenues to global trade.

Cutting Our Losses Interactive Map

The Natural Resources Defense Council (NRDC) has assembled a new resource to help plug the holes in our nation’s aging water infrastructure. According to the NRDC, “billions of gallons of water are lost every day from U.S. drinking water systems.” With climate change and demand patterns affecting water resources throughout the U.S., we need to do whatever it takes to monitor and prevent leakage system wide.

Twin Cities, MN: Water Sustainability in the Northeast Metro Area

Thursday, January 1st, 2015
Figure 1. Saint Paul Supply System Schematic

METROPOLITAN COUNCIL
The primary objective of this study is to understand the relative costs and implementation considerations of different approaches to water sustainability. The northeast metro provides a study area for this evaluation. The Minnesota Legislature requested this part of the metro area to be studied specifically, given the continued concern over lake levels and the interaction of groundwater and lakes in the area, especially White Bear Lake. The study area includes 13 communities. The results will be incorporated in the Twin Cities Metropolitan Area Master Water Supply Plan. The study will be referenced to support future planning of metro area water supplies and water sustainability practices.

CNA CORPORATION
To determine how Texas could be affected by the U.S. Environmental Protection Agency’s (EPA’s) Clean Power Plan (CPP), we applied CNA’s Electricity-Water-Climate power sector model to evaluate the potential impacts. We find that under the CPP, the state will save water and reduce levels of conventional air pollutants. In addition, the state will be able to meet the policy’s targets with modest incremental effort even though electricity demand is expected to increase by 25 percent.

Video: Flood Resilience Guide

Drinking water and wastewater utilities are vulnerable to damage and service disruptions from flooding. This overview video helps small and medium utilities to become more resilient to flooding. Told from the perspective of a small drinking water utility, the video introduces a 4 step approach with easy-to-use worksheets with corresponding videos. The utility is provided with the tools to examine the threat of flooding, determine impacts to utility assets, identify cost-effective mitigation options, and plan to implement such options.

EPA Program to Protect Underground Drinking Water Needs Improvement

Figure 1: Injection Wells for Enhanced Production and Wastewater Disposal

UNITED STATES GOVERNMENT ACCOUNTABILITY OFFICE
Every day in the United States, at least 2 billion gallons of fluids are injected into over 172,000 wells to enhance oil and gas production, or to dispose of fluids brought to the surface during the extraction of oil and gas resources. These wells are subject to regulation to protect drinking water sources under EPA’s UIC class II program and approved state class II programs. Because much of the population relies on underground sources for drinking water, these wells have raised concerns about the safety of the nation’s drinking water.
