The 3M and DuPont settlements have set the criteria for determining PFAS settlement amounts that will be offered to cities and public water systems grappling with PFAS contamination in their source waters.

The Settlements

Cities with detectable levels of PFOA and PFOS in their source waters will soon be hearing from claims administrators, if they haven’t already, regarding the 3M and DuPont settlements. The 3M settlement will be between $10.3 billion and $12.5 billion, depending on the number of claimants and the Dupont settlement is $1.185 billion for affected water systems. Money for capital investments (60 percent of the allocation) will be available as early as mid-2024 and dollars for operations and maintenance (40 percent of the allocation) will be distributed over the next several years.

3M Settlement amounts will be based on PFOA and PFOS levels and Adjusted Flow Rates as described in the following tool. Claim administrators will use a similar tool to determine DuPont settlements amounts (approximately one tenth of the larger 3M settlement amounts).

3M Public Water Provider Settlement Estimated Allocation Range Table

These 3M and Dupont settlement dollars are not expected to make communities with PFAS contamination whole (cover all the possible damages/costs). They do, however, offer the certainty of some financial relief for public water systems with PFOA or PFOS detected in their source water.

Opting In

Cities need to determine if opting in makes sense for their respective communities. Public water systems have a 90-day opt-out period to decide whether to participate in these settlements. The opt-out deadlines are as follows:

• DuPont: December 4, 2023
• 3M: December 11, 2023

Here are some key points cities should consider when deciding to opt-in or opt-out:

• Time Value of Money: The settlements provide a source of immediate funding, allowing cities that opt-in to lock in PFAS-related settlement dollars promptly. If a water system opts-out, they waive their right to pursue future litigation against 3M and Dupont and move to the end of the line. There is not guarantee of the amount of timing of any future funding.
• Legal Council Costs: Participating communities without counsel are likely to be assessed fees as a tax, while participating communities with counsel will not be charged this fee.

The Minnesota Department of Health (MDH) and the Minnesota State Fair (MSF) are an unlikely duet, yet in 2023 they are singing the praises of Biological Filtration.

• The Minnesota Department of Health – Acknowledged Biological Filtration’s ability to naturally achieve Optimal Corrosion Control Treatment (OCCT) and compliance with the Revised Lead and Copper Rule (LCR), in lieu of adding very expensive manmade chemicals like orthophosphate.
• The Minnesota State Fair – Le Sueur Minnesota, a community which WSB’s director of Water and Wastewater helped convert to Biological Filtration in 2013, was awarded third place among communities with the best tasting water at the 2023 State Fair.
  

The Corrosion / Taste Connection:

Biological Filtration ensures that all nitrification (the conversion of ammonia to nitrate) occurs in the water treatment plant filters and not in the finished water distribution system; it also allows for the addition of chlorine after complete nitrification has occurred.

• Avoiding nitrification in the distribution system is THE critical factor in the successful control of corrosion in Minnesota ground water systems.
• Achieving complete nitrification prior to the addition of chlorine vastly improves the ability to achieve and maintain great natural tasting water in the distribution system and all the way to the consumer’s tap.

Current Studies Reveal Other Practical Benefits:

WSB is piloting biological filtration for several metro area communities. Some of these communities are considering harnessing biological filtration to reduce capital and chemical costs for their future water plant expansions. Orthophosphate would not need to be added if Biological Filtration is approved as the OCCT. The currently projected capital and chemical savings for one of these communities are as follows:

How WSB Has Helped and Can Help

For decades, Steve Nelson has been teaching about Corrosion Control, singing the praises of Biological Filtration and making the connection between the two. “It is now a joy to see our local communities harnessing nature to produce safe, sustainable, solutions that provide natural corrosion control, reduced capital costs, reduced chemical costs and improved taste at the consumer’s tap.” (Steve Nelson, WSB)

Smart city technology has proven to be a game changer in water management, revolutionizing how cities handle their water resources. Smart cities are leveraging innovation to improve water management, leading to increased efficiency, cost savings and proactive decision-making. Technology adoption to gather data, enhance operations and plan improvements has become vital in progressing toward more streamlined and effective utility infrastructure.

How can your community benefit from smart water management? Here are three things to consider.

1. Efficiency through Technological Solutions
   
   Smart cities optimize water management processes with accurate and real-time data, allowing for increased infrastructure efficiency, which reduces energy consumption and lowers costs. Integrating computer models, field data and Supervisory Control and Data Acquisition (SCADA) systems can streamline operations and identify areas for rehabilitation or improvement in a water system.
   
   
2. Transforming the Water Management Lifecycle
   
   The impact of smart city technology is not limited to one phase of water management; it permeates the entire lifecycle. From the initial planning, design and construction stages to operation, maintenance and ongoing asset management, smart technology plays a vital role at every step. During design and construction, resources like 3D modeling create more accurate visual representations of supply, treatment, storage and distribution facilities and streamlines stakeholder and contractor communication, ultimately enhancing project outcomes.
   
   Once construction is complete, smart city technology continues to support asset management. 3D virtual models and Building Information Modeling (BIM) coupled with field data enables cities to monitor the condition of infrastructure, identify areas that require maintenance or rehabilitation and optimize around fluctuations in energy rates. By employing proactive strategies, cities can minimize disruptions, extend the lifespan of infrastructure and reduce operational and long-term costs.
   
   
3. Proactive Decision-Making and Risk Management
   
   Smart cities’ ability to be proactive in their water management practices sets them apart. By continuously monitoring and analyzing data, cities can detect potential issues before they escalate and prioritize rehabilitation and replacement budgets. Predictive analytics allow municipalities to identify potential issues and replace aging water main lines in advance of breaks and failures. This proactive approach minimizes disruptions to residents, improves service reliability and reduces emergency repair costs.

How WSB Can Help Your Community Be Smart About Water Management

WSB adopts a strategic approach to water management in smart cities, from planning, design and construction to asset management and beyond. Using state of the art technology and data-driven insights, we enhance project execution and improve asset management. Our approach enables cities to leverage smart technology in delivering high-quality water service to their residents and businesses.
