A significant portion of the meeting was dedicated to exploring different scenarios for water treatment, with a focus on the potential impact on water hardness and PFAS levels. Scenario four, which included a projected cost of $103 million plus additional expenses, was a topic of concern due to its high financial burden and operational costs of approximately $1.2 million annually. Conversely, scenario five was discussed for its relatively lower operating costs of around $275,000.

Particular attention was given to scenario two, which focused primarily on treating PFAS without addressing the issue of water hardness. This scenario sparked considerable debate due to concerns that it might exacerbate existing hardness problems, leading to future complications. One participant voiced apprehension about the practicality of scenario two, noting that it could lead to financial expenditure without resolving the hardness issue, which remains a critical concern for residents. There was a clear consensus that any decision should prioritize both affordability and the effectiveness of the treatment solutions.

The meeting also highlighted the importance of public engagement and understanding regarding these potential scenarios. Concerns were raised that residents might favor scenario two due to its perceived lower cost, without fully appreciating its long-term implications on water hardness. A proposal was made to include a footnote in the scenario descriptions, warning residents of the potential increase in water hardness if certain options were chosen. This suggestion aimed to ensure transparency and provide the community with comprehensive information to make informed decisions.

In addition to the discussion on treatment scenarios, the board explored the issue of water hardness in detail. The current water hardness levels were noted to be high, with existing wells showing levels of 220 and test wells indicating slightly improved, yet still concerning, levels of 140 and 160. In comparison, nearby areas such as Lancaster and Hicks reported much lower hardness levels of 30 and 40, respectively. The ongoing challenges with hard water were illustrated through practical examples, such as its impact on washing vehicles. These discussions emphasized the need for effective solutions to mitigate water hardness, which remains a concern for the community.

The meeting also addressed recent PFAS sampling results, revealing alarming levels exceeding regulatory limits. One well exhibited a PFAS level of 4.94, surpassing the maximum allowable threshold of four. While one well passed the testing with low PFAS levels, the overall situation was deemed precarious, with other wells failing to meet safety standards. The board discussed using a rolling average to evaluate compliance and the implications of exceeding these limits on public health and safety.

Public comments further highlighted community concerns, with a resident raising issues about canoes in a restricted area near the Hickory Hills Wake Lake well. The board acknowledged the potential risk to drinking water and committed to addressing the issue with responsible parties. Additionally, a resident commented on dissatisfaction with a $25 surcharge on water bills, which had since been reduced. This prompted a suggestion for residents to review their bills closely to understand the changes.
