In general, they include pharmaceuticals, personal care products, natural hormones, by-products of cleaning, and other compounds in water and wastewater than may exhibit a physiological response
(particularly in lower organisms) at very low levels.
ng/L = one drop of liquid in ten miles of railroad tankers.
Neither shallow soils systems or conventional treatment systems appear to be effective for the removal of: • Fire retardants (TCEP) • Anti-fungal medications
• Microbial diversity • Aerobic environment • Soil type • Factors still to be clarified
Data suggest that nitrifying
organisms may use certain CEC
as a carbon source.

SOIL COLUMNS
The general pattern of higher attenuation in soils containing 5%-10% fine material was found for acetaminophen, atenolol, atorvastatin, caffeine, DEET, diclofenac, ibuprofen, naproxen, sulfamethoxazole, and trimethoprim.
No significant difference with soil type was observed with the compounds • Furosemide • Propranolol • Miconazole • TCEP

Is there any hope for eliminating TCEP and similar compounds?

• Nature of the compound
• Oxygen availability
• Bacteria and other fauna
diversity in the receiving
environment
• Retention time during treatment
Take home messages • Many pharmaceutical and personal care products,
contain compounds that can disrupt the normal functioning of hormones in humans and wildlife.
• Although a major route for CEC entrance into the environment is wastewater disposal, the onsite septic system presents opportunity for significant treatment.
• Shallow-placed soil absorption systems remove > 90% of many CECs found in household wastewater.
• A more complete understanding of the principles of CEC removal in soils may offer opportunities to design optimization.
