This study focused on the evaluation of health of As and heavy metal contaminated soils following soil washing. Particle separation (2-0.075 mm) and acid washing by HCl (0.1, 0.5, and 1.0 M) were applied to remediate the contaminated soils. The eight soil health indices (bulk density, pH, electric conductivity, cation exchange capacity, soil organic material, available P 2 O 5 , soil respiration, β -glucosidase) were examined to quantify the variation of these properties after soil washing. Remediation efficiency increased with particle separation and increasing acid concentrations. Except for bulk density and electric conductivity, most soil health indices decreased after soil washing. These results provide important information on recycling of remediated soils and enhancing soil health.
