Village of Glasford - Regulated Contaminants Table

IMPORTANT INFORMATION

GLASFORD , IL WATER PERMIT# IL1430350 Annual Drinking Water Quality Report for period 1/1/07 to 12/31/07

This report is intended to provide you with important information about your drinking water and the efforts made by the GLASFORD water system to provide safe drinking water. The source of drinking water used by GLASFORD is Ground Water. For more information regarding this report contact: HAROLD ROBERTS at 309/389-5152. Este informe contiene información muy importante sobre el agua que usted bebe. Tradúzcalo ó hable con alguien que lo entienda bien. The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and groundwater wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pickup substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include: Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations and wildlife. Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban storm water runoff, industrial, or domestic wastewater discharges, oil and gas production, mining, or farming. Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses. Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems. Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA's Safe Drinking Water Hotline at (800) 426-4791. In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health. Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

A Source Water Assessment Summary: To determine Glasford's susceptibility to groundwater contamination, a Well Site Survey, published in 1991 by the Illinois EPA, and Source Water Protection Plan were reviewed. Based on the information contained in these documents, fourteen potential sources of groundwater contamination are present that could pose a hazard to groundwater pumped by the Glasford community water supply wells. These include two stores/sales, a laundry, a below ground fuel storage, two machine shops/sheds, a fire station, a school, a hardware store, a printing, a photographic service, a grain elevator, an auto body, and an above ground fuel storage. Based on information provided by Glasford water supply officials, the following facilities, also indicted as potential sources in the site data table, have changed their status: Glasford Service Center (gone--business office), Illini Discount Auto Parts (gone--building demolished), Timber Hollis Fire Protection (moved to 575 feet from Well #1 and 400 feet from Well 2), and Glasford Grade School (gone--empty building). Based upon this information, the Illinois EPA has determined that Glasford Wells #1 and #2 are not susceptible to IOC, VOC, or SOC contamination. This determination is based on a number of criteria including: monitoring conducted at the wells; monitoring conducted at the entry point to the distribution system; and the available hydrogeologic data for the wells. In anticipation of the U.S. EPA's proposed Ground Water Rule, the Illinois EPA has determined that Glasford's community water supply wells are not vulnerable to viral contamination. This determination is based upon the evaluation of the following criteria during the Vulnerability Waiver Process: the community's wells are properly constructed with sound integrity and proper site conditions; there is a hydrogeologic barrier that restricts pathogen movement; all potential routes and sanitary defects have been mitigated such that the source water is adequately protected; monitoring data did not indicate a history of disease outbreak; and the sanitary survey of the water supply did not indicate a viral contamination threat. However, having stated this, the U.S. EPA is proposing to require States to identify systems in karst, gravel and fractured rock aquifer systems as sensitive. Water systems utilizing these aquifer types would be required to perform routine source water monitoring. Because the community's wells are constructed in a confined aquifer, which should provide an adequate degree of protection to prevent the movement of pathogens into the wells, well hydraulics were not considered to be a significant factor in the vulnerability determination. The Illinois Environmental Protection Act provides minimum protection zones of 200 feet for the Village of Glasford's wells. These minimum protection zones are regulated by the Illinois EPA. Because the village has proceeded with source water protection efforts, the facility has received a monitoring waiver for its wells. To further minimize the risk to the village's groundwater supply, the Illinois EPA recommends that three additional activities be assessed. First, the village may wish to enact a "maximum setback zone" ordinance. These ordinances are authorized by the Illinois Environmental Protection Act and allow county and municipal officials the opportunity to provide additional protection up to a fixed distance, normally 1,000 feet, from their wells. Second, the water supply staff may wish to revisit their contingency planning documents. Contingency planning documents are a primary means to ensure that, through emergency preparedness, a community will minimize their risk of being without safe and adequate water. Finally, the water supply staff is encouraged to review their cross connection control program to ensure that it remains current and viable. Cross connections to either the water treatment plant (for example, at bulk water loading stations) or in the distribution system may negate all of the source water protection initiatives provided by the community and circumvent the natural protection provided to the aquifer.
