Proper design and quality of soil play an important role in the functioning of soil-based septic systems. Septic systems with traditional leach fields are not suitable for treatment of domestic wastewater in Ohio due to shallow soils. Along with other adverse health effects, untreated or partially treated wastewater could lead to a loss of property valuation. The assessed value of 549 randomly selected properties in Licking County, Ohio was analysed using hedonic pricing method to isolate the effect of poor site selection on the value of the properties. Results indicate that properties sited on soils that are deemed optimal for wastewater treatment are valued 6.2% to 6.8% higher than those sited on sub-optimal soils. The results from this study can help the property owners in making better private decisions regarding installation of septic systems, but can also guide policy decisions that affect public health and common waters.
