“…Fifteen months after the fire all PAH concentrations in water approached their background levels. Campos et al (2012) results contrast with ours and those by Vila-Escalé et al (2007), in the runoff collected immediately after the fire. Campos et al (2012) found that BaA was the prevailing dissolved PAH in the overland flow produced by the first post-fire rainfall events, with a concentration of 53.4 ng L −1 .…”

“…Campos et al (2012) results contrast with ours and those by Vila-Escalé et al (2007), in the runoff collected immediately after the fire. Campos et al (2012) found that BaA was the prevailing dissolved PAH in the overland flow produced by the first post-fire rainfall events, with a concentration of 53.4 ng L −1 . However, in the samples collected one year after the fire, NAP became the main PAH in the dissolved phase (with values slightly higher than in the first sampling time -14.8 vs. 24.5 ng L −1 ).…”

“…To date, only one study has carried out eco-toxicological assays of post-fire runoff, revealing that runoff collected immediately as well as one year after a wildfire was toxic to a battery of standard organisms (Campos et al, 2012). The current knowledge gap on the eco-toxicological impacts of post-fire runoff is particularly pertinent in the light of the EU Water Framework Directive (WFD) as the WFD requires the estimation and identification of significant diffuse sources of pollution.…”

“…However, contamination by pyrolytic substances has increasingly received research attention, in particular polycyclic aromatic hydrocarbons (PAHs) and chemical elements (Campos et al, 2012;Ignatavičius et al, 2006;Olivella et al, 2006;Schäfer et al, 2010;Smith et al, 2011;Vila-Escalé et al, 2007). Both PAHs and certain chemical elements like metals are contaminants of major biological concern, due to their high toxicity, environmental persistence and tendency to bioaccumulate (e.g., Manoli and Samara, 1999;Vila-Escalé et al, 2007).…”

Abstract. This study evaluated the performance of the WRF-ARW (Weather Research and Forecasting with AdvancedResearch) weather prediction model in simulating the spatial and temporal patterns of an extreme rainfall period over a complex orographic region in north-central Portugal. The analysis was performed during the rainy season and, more specifically, the month of December 2009. In this period, the region of interest was under the influence of a sequential passage of low-pressure systems associated with frontal surfaces. These synoptic weather patterns were responsible for long periods of rainfall, resulting in a high monthly precipitation.The WRF model results during the study period were furthermore evaluated with the specific objective to complement gaps in the precipitation recordings of a reference meteorological station (located in Pousadas), the data of which are fundamental for hydrological studies in nearby experimental catchments.Three distinct WRF model runs were forced with initial fields and boundary conditions obtained from a global domain model: (1) a reference experiment with no nudging (RunRef); (2) observational nudging for a specific location, i.e. the above-mentioned Pousadas reference station (RunObsN); and (3) nudging to the analysed field (RunGridN). Model performance was evaluated, using several statistical parameters, against a dataset of 27 rainfall stations that were grouped by elevation. The three model runs had similar performances, even though RunGridN resulted in a slight improvement. Regarding the other two experiments, this improvement justifies its use for complementing the surface measurements at the Pousadas reference station. Overall model accuracy, expressed in root mean square error (RMSE), of the three runs was comparable for the stations of the different elevations classes. Even so, it was slightly better for stations in the lowlands than the highlands. Furthermore, model predictions tended to be less accurate for stations located in rough terrain and deep valleys.

Wildfire damage and contamination to private drinking water wells

et al. 2023

Following the 2021 Marshall Fire in Colorado, this study was conducted to better understand private well and plumbing damage and to develop public health guidance. More than 20 post‐fire drinking water well guidance documents with varied recommendations were found. Approximately 227 wells were located in the fire footprint. Seventeen properties were visited, and a subset of wells were sampled for organic and inorganic contaminants. Property debris was also collected. Benzene, toluene, and 19 semi‐volatile organic compounds (SVOCs) were detected in water extracts of property debris. No wells contained volatile organic compound contamination. Two shallow wells (12 and 15 ft) had debris contamination; one well contained notable SVOC contamination. One multi‐home unregulated well system was extensively damaged, lost pressure, and had not been repressurized 11 months after the fire due to financial and technical challenges. Study results highlight the need for follow‐up work to understand well system damage and household response.
