Carbonate coprecipitation using sodium or calcium carbonate can also be helpful; for example, for soluble ,lead, reduction, ,lead, carbonate is essentially insoluble (0.00011 g/100 mL at 20°C) and will precipitate out. Phosphate precipitation is another option, although this process is not as common.

Acceptable Lead Levels in Wastewater and the Need for Removal
Acceptable Lead Levels in Wastewater and the Need for Removal

When contaminated wastewater is improperly discharged to waterways or to wastewater treatment facilities, lead can make its way into aquatic and terrestrial ecosystems. Over time, lead can accumulate in sediments, soils, plants, and animals, with consequences such as inhibited plant growth and contamination of drinking water and food supplies.
