Impact of Wildfires on Water Quality

Wildfires alter watershed hydrology and geochemistry in ways that can persitt for years. Te divity of water quality impacts depens on fire intensity, watershed charakteristics, soil type, and thee timing and intensity of post- fire rainfall. Unterstanding these effects is essential for designing determinate policy responses.

High- intensity fires burn vegetation and organic soil layers, leaving the ground bare and water- repelent. This reduces infiltration and dramatically increates surface runoff. The first teavy rains after a wildfire can trigger massive erosion events, sending tons of sediment, ash, and debris into rainto raint capacity of contrained raiss. Sediment nailing raises turbidity levels, clogs water intare structures, and can exceed cail capacity of contintionar wateur cases.

Chemical Contaminants: Ash, Metals, and Pyrolytic Compounds

Ash from burned vegetation conceps various elements, including calcium, potassium, magnesium, and trace metals, but also potentially toxic teasty metals such as arsenic, lead, and mercury that were stored in forrett soils and litter. When ash washes into water bodies, it can elevate diversitent levels (nitrogen and fosforu), inconcentring algal blooms that produce toxins and further degrame water qualicy.

Biological and Microbial Risks

Post- fire conditions can also evete microbial contamination. Loss of vegetative cover reduces natural filtration, alloing pathogens from animal carcasses, septic systems, or burned infrastructure to enter waterways. Warmer water temperatures in post- fire fairs may promotte bacterial growth.
