About Us
The following pages contain important information about Organic Carbon removal. Each month, the percentage of Total Organic Carbon (TOC) removal is measured, and the system has met all TOC removal requirements unless otherwise noted in the violations section.
Turbidity (NTU) measures water cloudiness and serves as an excellent indicator of water quality and filtration effectiveness. Sodium monitoring provides information for consumers and health professionals concerned about sodium intake due to dietary restrictions. There is no State or Federal maximum contaminant level (MCL) for sodium. Those on sodium-restricted diets should consult healthcare providers about sodium levels in their water.
Lead & Copper - The Village maintains compliance with regulations for lead and copper control. Unregulated Contaminants are monitored to help the EPA determine their prevalence in tap water and whether future regulation is warranted, though MCLs haven't been established by state or federal agencies.
Beyond mandated testing, Deerfield continuously monitors your water through automated control systems and weekly physical sampling. These samples are analyzed by the Central Lake County Joint Action Water Agency, an EPA-certified laboratory, ensuring rapid response to any potential issues.
Water sources (both tap and bottled) include rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over land or through the ground, it dissolves naturally occurring minerals and radioactive material while also collecting substances from animal presence or human activity. Potential contaminants include microbial pollutants (viruses, bacteria), inorganic contaminants (salts, metals), pesticides and herbicides, organic chemicals, and radioactive contaminants.
EPA regulations limit contaminant levels in public water systems, while FDA regulations establish similar protections for bottled water. The Village of Deerfield and City of Highland Park routinely monitor for contaminants in accordance with federal and state requirements.

Name Origin and Founding
Originally settled in 1835, the Deerfield Township area was initially known as Leclair in 1840. The name "Deerfield" was adopted around 1849-1850 during Lake County township formations, inspired by Deerfield, Massachusetts and the abundant local deer population. Irish settlers had advocated for the name "Erin" but lost by a narrow margin - 17 votes for Deerfield versus 13 for Erin.
Local Government Evolution
Township government was the first administrative structure, with meetings held in residents' homes until approximately 1870 when the Township Hall was constructed on Deerfield Road at Ridge Avenue (now part of Highland Park). Following the 1887 division into East and West Deerfield Townships, the Township Hall relocated to 602 Deerfield Road.
Village Incorporation
The Village of Deerfield was officially incorporated in 1903 with John C. Ender serving as the first President of the Village Board. His former residence still stands at the southwest corner of Waukegan Road and Westgate Avenue. Board meetings were held in the Township Hall until 1923, then moved to the Masonic Temple at 711 Waukegan Road until April 1957, when the current Deerfield Village Hall was established at 850 Waukegan Road.
