How Old Is South Holland's Housing Stock?
With 90% 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
While newer cities carry lower aggregate plumbing risk from lead-era construction, South Holland sits firmly in the older category. The median build year of 1963 indicates that more than half the housing stock was built before 1986, when lead solder was still legally used in residential copper plumbing — and a substantial portion likely predates 1970, when lead pipes were still commonly installed for service lines. These two thresholds together define the elevated plumbing risk environment that older housing cities carry, independent of what the municipal water supply delivers to the meter.
Over half of homes in South Holland were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

South Holland: Remediation Cost in Perspective
Given current South Holland property values, the remediation share falls in the moderate tier — an indicator that the household financial perspective here calls for advance planning rather than dismissal, with most homeowners positioned to address documented issues through deliberate budgeting rather than needing to treat remediation as a significant equity event or financial emergency.
Remediation costs are moderate relative to home values in South Holland. The estimated $1,250–$4,000 range is manageable for most homeowners but still worth budgeting for. Home values are 9% above the Illinois average.
Protecting Children from Lead in South Holland
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.
Households with kids in the home — for whom CDC guidance places particular weight on minimizing exposure — face a specific local picture in South Holland. 90% of homes here come from the pre-rule era, and aggregate utility samples either approach or cross 0.015 mg/L. A baseline draw-test kit and certified lead-removal filtration are available via retailer networks for households confirming conditions at a specific tap.

Climate-Related Water Risk for South Holland
Over the multi-decade span covered by the National Flood Insurance Program, South Holland has accumulated 776 flood claims — a total that reflects a community where significant flooding is a recurring, documented feature of the local environment. That history has direct relevance to water quality. Each major flood event activates contamination pathways that are absent or dormant during dry conditions: treatment plants handling floodwater-saturated intake face sharply elevated contaminant loads; private wells in low-lying FEMA-designated zones — which cover 100% of local ZIP codes — can be infiltrated by surface runoff carrying bacteria, sediment, and chemical residue; distribution systems under pressure during flooding can experience backflow that draws untreated water into the supply.
South Holland has a significant flood history with 776 FEMA flood insurance claims on record, averaging $3,404 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,400</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
