Key Contaminants Detected in Tiskilwa
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Tiskilwa's Housing Stock?
With 91% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Because the majority of Tiskilwa's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1945 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Tiskilwa were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Tiskilwa: Remediation Cost in Perspective
How does remediation fit within the broader financial picture for Tiskilwa homeowners? The equity share is moderate — large enough that treating it as a real planning consideration makes sense, and manageable enough that most homeowners have a clear path to addressing documented water and safety issues when they approach the commitment with deliberate advance budgeting rather than as an unplanned expense.
Remediation costs are moderate relative to home values in Tiskilwa. The estimated $950–$2,100 range is manageable for most homeowners but still worth budgeting for. Home values are 35% below the Illinois average.
Protecting Children from Lead in Tiskilwa
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Older stock in Tiskilwa represents 91% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
