It is possible that minute amounts of these contaminants may be found in drinking or tap water, however the amount found in the community’s water supply is negligible. Treatment reduces and eliminates these contaminants, and all publicly used water in Hanover Park contains no more than the EPA mandated maximum levels.

According to a 2014 annual drinking water quality report, Hanover’s source water is not subject or vulnerable to contamination, including viral contamination. The EPA administered tests from primary and secondary sources of well water. The results from these tests led the EPA to determine that the water supplied to residents of Hanover Park is clean and contamination free due to the integrity of the wells structure (they are constructed with a confined aquifer), locations of the wells (mandatory distance from areas that could cause contamination), preventative measures used to restrict movement of pathogens, procedures to purify the water, and the monitoring and operations that mitigate possible sanitary defects.

The EPA also disclosed evidence stating there had been no history of disease or illness cause by the community’s water. Through their findings, the EPA revealed that Hanover’s water supply, including tap and bottled water, indicate no reason for the community to believe they can be harmed or diagnosed with any type of illness from consuming Hanover’s water.
