WELLFIELD PROTECTION PROGRAM

Do you know that less than 1% of the earth’s water is fresh water, and only about one-third of this 1% is available for human use? That means that only one-third of one percent of ALL the worlds water is available for drinking water, and most of this water is contaminated in some way.

A majority of Marion County’s drinking water comes from surface water like rivers, lakes, and streams. However, a considerable amount of freshwater is in the ground in the form of groundwater. Approximately 30% of Marion County’s drinking water comes from groundwater supplies. That means a third of all our drinking water is below ground, and comes to us via groundwater wells.

In order to protect this precious resource the Marion County Public Health Department Hazardous Materials Team conducts inspections of regulated businesses within Marion County’s seven Wellfield Protection Areas. These inspections are intended to protect our groundwater from contamination, which will allow us to continue to use this very scarce resource. Marion County first initiated an inspection program to protect groundwater in the mid-1990s with the implementation of the Marion County Wellfield Protection Zoning Ordinance. This ordinance was developed to ensure that all proposed developed business sites constructed in a Wellfield Protection Zoning District are conducting safe handling practices of potential groundwater contaminants. In January 2017, the Marion County Public Health Department established the Marion County Wellfield Protection Standards Ordinance which broadened these regulatory standards to include all new and established businesses operating in a Wellfield Protection Area. Staff members work directly with facilities to ensure compliance, and to encourage best business practices for facilities operating a business while storing, handling, managing, and/or transporting potential groundwater contaminants.

Inspection frequency is determined using several site specific factors including types and amounts of chemicals stored at a location, facility history including past spills, and previous inspection history.
