The quality of water depends primarily on the concentration of bacteria, lead, pesticides, nitrites/nitrates, chlorine, hardness, and the water’s pH. Chlorine aids in disinfecting; nitrates leached from fertilizers are harmful to infants; calcium and magnesium (“hardness”) can cause scale buildup in pipes, and water with very high pH levels (acidic water) can corrode fixtures.
