These data are of spore removal from an asphalt parking lot using a power washer and garden hose and different wash aids.

After a wide-area biological contamination incident populations residing within minimally contaminated areas may be instructed to shelter-in-place and need to perform infection control within their homes. Previous research within HSMMD has found hot water laundering effective for the decontamination of Phi6 bacteriophage and hot water laundering + bleach effective for the decontamination of the B. anthracis surrogate Bg. This dataset expands upon previous work to include six different laundering methods, some including sanitizers, and four different microorganisms (Phi6, MS2, Klebsiella pneumoniae, and Staphylococcus aureus). The dataset includes eight different textiles.

The data set is a spreadsheet that contains results of inactivation experiments that were conducted to to determine the effectiveness of chlorine in inactivating B. anthracis spore surrogates in wash waters similar to waters that would be generated during building decontamination activities. This dataset is associated with the following publication: Gallardo, V., D. Schupp, J. Heckman, R. Krishnan, and E. Rice. Inactivation of Bacillus Spores in Wash Waters Using Dilute Chlorine Bleach Solutions at Different Temperatures and pH Levels. WATER ENVIRONMENT RESEARCH. Water Environment Federation, Alexandria, VA, USA, 1-36, (2017).

Decontamination of Bacillus spores adhered to common drinking water infrastructure surfaces was evaluated using a variety of disinfectants. Corroded iron and cement-mortar lined iron represented the infrastructure surfaces, and were conditioned in a 23 m long, 15 cm diameter (75 ft long, 6 in diameter) pilot-scale drinking water distribution pipe system. Decontamination was evaluated using increased water velocity (flushing) alone at 0.5 m sec-1 (1.7 ft sec-1), as well as free chlorine (5 and 25 mg L-1), monochloramine (25 mg L-1), chlorine dioxide (5 and 25 mg L-1), ozone (2.0 mg L-1), peracetic acid 25 mg L-1) and acidified nitrite (0.1 mol L-1 at pH 2 and 3), all followed by flushing at 0.3 m sec-1 (1 ft sec-1). Flushing alone reduced the adhered spores by 0.5 and 2.0 log10 from iron and cement-mortar, respectively. Log10 reduction on corroded iron pipe wall coupons ranged from 1.0 to 2.9 at respective chlorine dioxide concentrations of 5 and 25 mg L-1, although spores were undetectable on the iron surface during disinfection at 25 mg L-1. Acidified nitrite (pH 2, 0.1 mol L-1) yielded no detectable spores on the iron surface during the flushing phase after disinfection. Chlorine dioxide was the best performing disinfectant with >3.0 log10 removal from cement-mortar at 5 and 25 mg L-1.The data show that free chlorine, monochloramine, ozone and chlorine dioxide followed by flushing can reduce adhered spores by >3.0 log10 on cement-mortar.
