Report on Central Iowa Water Quality and Infrastructure Strain in Relation to Sustainable Development Goals
Executive Summary
Central Iowa is facing a significant challenge in maintaining safe drinking water, directly impacting the achievement of several United Nations Sustainable Development Goals (SDGs). Elevated nitrate levels in the Raccoon and Des Moines Rivers have placed unprecedented strain on water treatment infrastructure. While recent data indicates a temporary dip in nitrate concentrations below the Environmental Protection Agency (EPA) standard of 10 mg/L, the situation highlights systemic vulnerabilities in water management, public health, and urban resilience. This report details the current status, the operational challenges, and the strategic responses being considered, all framed within the context of the SDGs.
Current Water Quality Status and SDG 6: Clean Water and Sanitation
The primary concern revolves around SDG 6, which aims to ensure the availability and sustainable management of water and sanitation for all. The region’s progress toward this goal is threatened by persistent nitrate contamination.
- Raccoon River: The latest test of untreated water showed a nitrate level of 7.93 mg/L.
- Des Moines River: The latest test of untreated water registered 9.52 mg/L.
While these figures are below the 10 mg/L violation threshold, officials require these levels to remain low for a sustained period to ensure public safety and lift conservation measures like lawn watering bans. This ongoing vigilance is critical for meeting Target 6.1: Achieve universal and equitable access to safe and affordable drinking water for all.
Infrastructure Challenges and Impacts on SDG 11: Sustainable Cities and Communities
The high nitrate levels have forced the Des Moines Water Works’ Fleur Drive facility to operate beyond its designed capacity, challenging the resilience of urban infrastructure as outlined in SDG 11.
Operational Strain at the Fleur Drive Facility
- The plant has been forced to run at full capacity for over 66 consecutive days.
- All eight of its nitrate removal tankers have been operating daily to process up to 10 million gallons of water.
- According to Des Moines Water Works COO Kyle Danley, the facility was never intended to meet such an unlimited and sustained demand for nitrate removal.
Capacity Limitations and Barriers to Expansion
The current infrastructure is insufficient for long-term high-nitrate conditions, creating a direct conflict with SDG 12 (Responsible Consumption and Production) due to the waste generated by the treatment process.
- Tanker Deficit: An estimated 26 tankers would be required to manage persistently elevated nitrate levels, but the facility currently possesses only 8.
- Wastewater Production: Each nitrate removal tanker produces nearly 50,000 gallons of wastewater, which must be processed by the Water Reclamation Authority.
- Processing Constraints: The Authority has stated it can only handle approximately 25% more wastewater than is currently being produced, which equates to the output of just two additional tankers. This limitation makes the acquisition of 18 new tankers unfeasible.
This situation underscores the difficulty in building resilient infrastructure (SDG 9) without creating downstream environmental pressures, a core tenet of sustainable development.
Strategic Responses and Partnerships for the Goals (SDG 17)
To address the crisis sustainably, Central Iowa Water Works is pursuing a multi-faceted strategy that aligns with several SDGs, including the crucial role of collaboration as highlighted in SDG 17 (Partnerships for the Goals).
- Upstream Contamination Control: A key long-term strategy involves working with “upstream partners” to reduce nitrate concentrations at their source. This collaborative approach is essential for protecting freshwater ecosystems (SDG 15: Life on Land) and ensuring the long-term health of the water supply, which directly supports SDG 3 (Good Health and Well-being).
- Infrastructure Expansion: Plans are underway to expand other treatment plants, such as those in Saylorville and Grimes. This will distribute the treatment load, reduce the strain on the Fleur Drive facility, and build a more resilient and sustainable water system for the community (SDG 11).
These forward-looking actions are vital for ensuring that central Iowa can meet its water needs safely and sustainably, making tangible progress toward the global Sustainable Development Goals.
Analysis of Sustainable Development Goals in the Article
1. Which SDGs are addressed or connected to the issues highlighted in the article?
-
SDG 6: Clean Water and Sanitation
This is the most central SDG in the article. The entire text focuses on the challenges of providing safe drinking water due to contamination from high nitrate levels in the Raccoon and Des Moines rivers. It discusses water quality, water treatment processes, and the infrastructure required to ensure water is safe for consumption.
-
SDG 3: Good Health and Well-being
The article’s emphasis on keeping drinking water safe directly relates to protecting public health. The concern over nitrate levels is driven by health standards, as indicated by the reference to the EPA’s violation standard. High nitrate levels in drinking water are a known health risk, so efforts to remove them are actions to prevent water-borne illnesses, connecting directly to this goal.
-
SDG 11: Sustainable Cities and Communities
The issue is framed as a significant challenge for the urban infrastructure of central Iowa. The article details how the Des Moines Water Works facility is being pushed “to the brink,” highlighting the strain on essential public services. The discussion about the feasibility of expanding the treatment plant, the generation of wastewater, and the need to manage demand all fall under the goal of making cities and human settlements inclusive, safe, resilient, and sustainable.
2. What specific targets under those SDGs can be identified based on the article’s content?
-
SDG Target 6.1: Achieve access to safe and affordable drinking water
The article is fundamentally about the struggle to meet this target. The efforts of Central Iowa Waterworks to “remove excess nitrate from drinking water” and “produce safe drinking water to our public” despite contamination are direct actions toward achieving safe drinking water for the population of central Iowa.
-
SDG Target 6.3: Improve water quality by reducing pollution
This target is addressed by identifying the problem of “elevated nitrate levels” in the source water (Raccoon and Des Moines rivers). The article mentions that the utility is “working with our upstream partners… trying to help encourage and see lower nitrate concentrations in our rivers,” which is a strategy aimed at improving ambient water quality by addressing pollution at its source.
-
SDG Target 3.9: Reduce illnesses from hazardous chemicals and water pollution
The entire operation described in the article is a measure to prevent public illness. By ensuring nitrate levels remain “below the EPA’s violation standard” of 10 mg/L, the water utility is actively working to mitigate the health risks associated with chemical contamination in drinking water, thereby contributing to this target.
-
SDG Target 11.6: Reduce the adverse environmental impact of cities
The article highlights a negative environmental consequence of the water treatment process. It states that each nitrate removal tanker “produces almost 50,000 gallons of wastewater that the Water Regulation Authority has to process.” The fact that the authority “cannot take the industrial loading of 26 vessels” points to a significant challenge in managing the city’s waste, which is a key component of this target.
3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?
-
Nitrate Concentration Levels
This is the most explicit indicator mentioned. The article provides precise measurements used to track water quality and safety. Specific values include the EPA violation standard of “10 mg per liter,” and the measured levels in the Raccoon River (“7.93 mg per liter”) and the Des Moines River (“9.52 mg per liter”). This directly measures progress towards Targets 6.1, 6.3, and 3.9.
-
Water Treatment Infrastructure Capacity and Strain
The article provides several metrics that serve as indicators of the resilience and capacity of the city’s water infrastructure. These include the facility’s maximum daily cleaning capacity (“10 million gallons of drinking water a day”), the duration of its operation at maximum capacity (“more than 66 days straight”), and the number of nitrate removal tankers currently in use (8) versus the number needed (26). These indicators measure the ability to meet Target 6.1 under stress.
-
Wastewater Generation and Management Capacity
An indicator for Target 11.6 is the volume of wastewater produced by the treatment process. The article states that each tanker “produces almost 50,000 gallons of wastewater.” Furthermore, the capacity of the wastewater authority is quantified, as it can “only take about 25% more than what we’re currently producing,” providing a clear metric for the city’s waste management limitations.
