7 News covers Mines study on wildfires and drinking water quality

7 News highlighted a new study conducted by Mines Civil and Environmental Engineering graduate students last semester that details how wildfires can be detrimental to drinking water quality and suggests what municipalities could do to respond to the threat.

Rain events following a wildfire can result in detrimental impacts on surface water quality in impacted areas. Run-off mixes with left over debris and sediment in a “chocolate milk shake-like mix” that can end up in drinking water sources. Increased turbidity (cloudiness), alkalinity and organic matter load can thwart purifying mechanisms inside a downstream water treatment plant. If a water plant is challenged by these conditions, the drinking water quality might be compromised including tap water that might have a smoky taste and perhaps doesn’t meet EPA drinking water standards.
