Water utilities play a critical role in ensuring that safe and clean water is delivered to communities. One area of concern for many water utilities is the presence of lead in drinking water, which can cause serious health problems. To address this issue, water utilities often maintain a lead line inventory, which involves identifying and replacing lead pipes in the distribution system. Geographic Information Systems (GIS) technology is often used to support these efforts, as it allows utilities to map and analyze the location of lead pipes in relation to other infrastructure and demographic data. This helps utilities to prioritize replacement efforts and ensure that resources are targeted where they are needed most. Overall, water utilities' use of GIS for lead line inventory is an important step in protecting public health and ensuring safe drinking water for all.
