Pharmaceuticals find their way into the drinking water supply in numerous ways, including but not limited to septic systems, landfills, and fertilization.
Contaminants of emerging concern are chemicals that have been discovered in the environment with no current regulatory standard to control them. Recently identified and discovered due to advances in science, these chemicals are concerning because their impacts on water quality, aquatic life, and human health are still unknown. The most well-known of these chemicals are classified as per- and polyfluoroalkyl substances, or PFAS.
What are PFAS?
PFAS are a group of 3,000 to 4,000 chemicals that have been manufactured and used in a variety of industries dating back to the 1940’s. The chemicals are persistent and accumulate over time, and there is evidence of negative health impacts from PFAS on humans and animals. PFAS are found in everyday consumer goods – generally speaking, anything that is water resistant, heat-proof, or stain resistant includes PFAS. Historically, the largest source of PFAS exposure is from firefighting foam which was used most frequently at and around airports.
Most people have been exposed to PFAS, but not necessarily at the elevated levels that are concerning. When tested, PFAS has been found in 97% of tested human blood samples. However, there is no large-scale sampling effort currently underway for PFAS in the United States.
How can the price of water in your community be changed to promote water conservation? How can municipalities price water to keep basic needs and services affordable for all residents while promoting reduced use? And what are the long-term benefits for the municipality?
What is conservation pricing?
Conservation pricing is water rate structures that motivate consumers to use water efficiently. These structures come in many forms, such as uniform rates, tiered rates, seasonal rates, and water budget-based rates. For all of these rate structures, wasteful or inefficient water use is more costly for customers than using only what they really need for drinking, cooking, sanitation, and cleaning.
Significant portions of the Chicago region – especially those dependent upon groundwater sources -- are encountering water supply and quality issues. The region’s comprehensive plan, ON TO 2050, anticipates these issues will grow unless additional steps are taken to coordinate and conserve the region’s shared water supply resources. The recently updated regional water demand forecast revealed that while overall water use is stable, projected demand will exceed available groundwater supplies in some areas. Yet with additional conservation and efficiency measures, the region can maintain its long-term drinking water supplies.
The Metropolitan Planning Council, along with partners the Chicago Metropolitan Agency for Planning (CMAP), the Illinois Section of the American Water Works Association and the Metropolitan Mayors Caucus, have created a peer-to-peer learning exchange and local technical assistance program — called the Drinking Water 1-2-3 Academy — to further assist communities in implementing best practices featured in MPC’s Drinking Water 1-2-3 guide.
Part one of this program is a series of four half-day events across the region that feature education about key best practices that target important local issues for decision makers and the communities they serve. The audience for these events is elected officials, community leaders and top municipal staff, and speakers will include community leaders and water experts with an emphasis on peer-to-peer learning and example case studies from the region.
The use of road salt to manage snow and ice on roadways and parking lots is polluting water throughout the Chicago region and beyond. While maintaining public safety during winter conditions is absolutely necessary, much of the salt applied to paved surfaces under current practices is excessive, leading to huge economic and environmental costs. The scale of this problem is massive because salt is applied to all paved surfaces including roads, parking lots, driveways and sidewalks.
The good news? There are Sensible Salting Best Management Practices (BMPs) that can safely manage snow and ice while reducing the amount of salt used. The bad news? Current practices that drive the excess use of salt are well-established. So how can we help change behavior and protect water resources?
With transportation agencies working on road salt reduction, the Northwest Water Planning Alliance (NWPA) Sensible Salting Sub-Committee has determined that the next greatest reduction can be achieved by changing salt use practices on parking lots.
Protecting and conserving our water supply is a priority of all water resource managers, public works directors, and municipal leaders in the Chicago area. What is one of the most efficient ways to address water conservation? Look at the lawns.
Landscape and lawn watering is the leading discretionary use of water in the Chicago region, accounting for more than thirty percent of all residential water use. Additionally, as much as fifty percent of all water used outdoors is wasted due to inefficient watering methods and systems.
This use puts a strain on existing water resources, particularly in Northwest Water Planning Alliance communities. It also impacts existing water infrastructure, causing peak usage to rise and increasing the need for additional capacity-building infrastructure, which can be of huge cost to communities.
The latest updates page features posts about issues affecting NWPA member communities and best practices, drawing on interviews and conversations with experts.
