How Does pH Affect Water Quality?
Increased pH levels cause a bitter taste to drinking water and supplies, water pipes, and other appliances become encrusted with deposits. Additionally, a high pH in water decreases the effectiveness of using chlorine as a disinfectant. On the other hand, high pH levels corrode or dissolve metals in water, increasing toxicity levels.
