Ethylenediaminetetraacetic acid - Wikipedia

Ethylenediaminetetraacetic acid is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-soluble solid is widely used to bind to iron and calcium ions. It binds these ions as a hexadentate chelating agent. EDTA is produced as several salts, notably disodium EDTA, sodium calcium edetate, and tetrasodium EDTA.

Adjusting the pH in Drinking Water | Denver Water

The pH level of drinking water reflects how acidic or basic it is. PH is measured on a scale of 0 to 14, with 7 considered neutral, meaning there’s a balance between the water’s acidity and basicity. For years, the water Denver Water delivered to customers had a pH that ranged between 7.5 to 8.5, with a target of 7.8.
