By far the largest source of drinking water for Missourians is surface water from the Missouri River.

Application Period is Open

Source water are the streams, lakes, springs and groundwater reservoirs used as a raw water source to produce potable drinking water. It is important to protect source water to ensure that everyone has access to clean, healthy drinking water. Creating and implementing preventative action plans, such as source water protection plans, reduces the need for costly treatment upgrades and protects the health and vitality of the community.

Section 1452(g) and (k) of the federal Safe Drinking Water Act authorizes the Missouri Department of Natural Resources to distribute part of the Drinking Water State Revolving Funds (DWSRF) set-asides to promote source water protection awareness, education and implementation. Through this grant program, the department provides financial assistance to community public water systems to develop and implement voluntary, local source water protection plans to protect the community’s raw water source(s) from contamination. The department anticipates accepting applications starting in February.
