Ph value of 4
WebThe pH of 4.6 is critical because of one particular bacterium, Clostridium botulinum. Clostridium botulinum produces a dormant form called a spore. These spores are found in the soil and in many other places. Spores are extremely hard to kill and may survive for many years waiting for a favorable environment to grow. Webgenerally, pH levels were measured before the arrival of the contaminant plume and found to range between 6.5 and 7.6. When the contaminated water from the mine release passed a sampling location, the pH lowered (indicating more acid) to approximately 4.8 (below Silverton). A pH of 4.5 is consistent with the pH of a liquid like black coffee.
