Huntley

Depending on the information obtained within a Well Site Study, published in 1989 by the Illinois ENVIRONMENTAL PROTECTION AGENCY, twenty-eight potential second source or possible problem site had been identified within the study area of Huntley boreholes. Furthermore, the information offered by the Leaking Subterranean Storage Tank Portion of the Illinois ENVIRONMENTAL PROTECTION AGENCY indicated several further sites with regular remediation, which may be of interest. The Illinois ENVIRONMENTAL PROTECTION AGENCY has determined the Huntley Community Normal water Supply's source of normal water is not vulnerable to contamination. This dedication is based on several requirements including monitoring carried out at the wells; monitoring conducted at the access point to the distribution program; and the available hydrogeologic data on the water wells. Furthermore, in anticipation of the U. S. EPA's proposed Ground Drinking water Rule, The state of Illinois EPA has identified that the Huntley Community Water Supply is certainly not vulnerable to viral toxins. This determination relies upon the analysis of the following conditions during the Vulnerability Waiver Process: the city's wells are correctly constructed with sound honesty and proper internet site conditions; a hydrogeologic barrier exists that ought to prevent pathogen motion; all potential paths and sanitary problems have been mitigated in a way that the source water is usually adequately protected; monitoring data did not signify a history of disease outbreak; and the hygienic survey of the hydrant did not indicate a viral contamination danger. Because the city's water wells are constructed within a confined aquifer, that ought to prevent the movement of pathogens into the boreholes, well hydraulics has not been considered a significant element in this vulnerability dedication. Hence, well hydraulics was not evaluated with this groundwater supply. The Illinois Environmental Security Act provides minimal protection zones of 200 feet meant for Huntley's wells. The Illinois EPA manages these minimum safeguard zones. Also, the city enacted a "maximum setback zone ordinance" for well #7, which is authorized by Illinois Environmental Safeguard Act and enables county and city and county officials the opportunity to give additional potential supply prohibitions up to one particular, 000 feet using their wells. To further decrease the risk to origin water, the city provides implemented a wellhead protection program, including the proper abandonment of potential routes of groundwater contamination and correction of hygienic defects at the normal water treatment facility. This hard work resulted in the community hydrant receiving a special exclusion permit from The state of Illinois EPA, which allows a decrease in monitoring. The outcome with this monitoring reduction features saved the center considerable laboratory evaluation costs. To further reduce the risk to the groundwater supply, The state of Illinois EPA recommends that three additional activities become assessed. First, metropolis may wish to enact a "maximum setback zone" ordinance for water wells #8, #9, #10 and #11 to help protect their hydrant. This ordinance is authorized by The state of Illinois Environmental Protection Action and allows region and municipal representatives the opportunity to provide more protection up to a set distance, normally one particular, 000 feet, off their wells. Second, the supply staff might wish to revisit their contingency planning documents. Backup planning documents are a primary means to make certain that, through emergency readiness, a city will lessen their risk of staying without safe and adequate water. Finally, the water supply personnel is encouraged to review all their cross-connection control program to ensure that remains current and viable. Cross contacts to either this particular treatment plant (for example, at mass water loading stations) or in the syndication system may negate all source drinking water protection initiatives furnished by the village..
