The town of Longmont’s water is all surface drinking water that comes from streams, ponds and reservoirs which can be fed by snowmelt and rainfall. The sources of Longmont’s water are: The St Vrain Creek watershed includes North and South St. Vrain Creeks, and St Vrain Creek. The North St. Vrain Creek watershed contains wilderness areas and portions of the Rugged Mountain National Recreation area. Ralph Price Tank is used to store drinking water from North St Vrain Creek. The South St. Vrain Creek watershed stretches into the Indian Highs Wilderness. The North and South forks combine to form St Vrain Creek close to the town of Lyons. The Highland Say goodbye to is used to convey drinking water from the St. Vrain for treatment. During this confirming year, 38% of Longmont’s water originated from North St. Vrain Creek and St Vrain Creek. Drinking water from St. Vrain Creek below the City of Lyons is usually conveyed to Burch Lake by the Palmerton Ditch. Burch Pond was not used in this reporting year. The Colorado and Fraser Rivers in Grand County. These resources are delivered to Longmont via the Colorado-Big Thompson (C-BT) project, managed by The causes of drinking water (both plain tap water and bottled water) include rivers, ponds, streams, ponds, reservoirs, springs, and water wells. As water moves over the surface from the land or throughout the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive components, and can pick up chemicals resulting from the presence of pets or liveliness. W H IN ’ S We N T They would E WAT Electronic R BEFORE TREATMENT? Contaminants that may be within source water consist of Microbial contaminants, including viruses and bacterias, which may come from sewerage treatment plants, solid waste systems, agricultural animal operations, and animals. Inorganic contaminants, including salts and alloys, which can be naturally-occurring or perhaps result from urban stormwater runoff, industrial or perhaps domestic wastewater secretions, oil and gas production, exploration, or farming. & nitrogen-laden herbicides, which may originate from a variety of sources including agriculture, urban stormwater runoff, and home uses. Organic chemical substance contaminants, including artificial and volatile organic and natural chemicals, which are by-products of industrial processes and petroleum production, and may also come from gasoline stations, urban stormwater runoff, and septic devices. Radioactive contaminants, which may be naturally-occurring or become the result of oil and gas creation and mining actions. Longmont is lucky to have high-quality drinking water sources that begin in mountain watersheds. The North St Vrain Creek watershed is mainly wilderness and it is affected only simply by naturally-occurring elements. Drinking water from the South St Vrain Creek might be impacted by runoff coming from abandoned mines. The watersheds that give food to the C-BT task may contain pollutants related to recreation, sewage treatment plant effluents and runoff coming from pastures. St. Vrain Creek below Lyons is transferred to the therapy plants by water sources ditches and can be impacted by agricultural and animal activities. To make sure that tap water is safe to imbibe, the Environmental Protection Company (EPA) prescribes codes that limit the number of certain contaminants in water provided by Longmont and other public drinking water systems. The City’s treatment plants decrease any contaminants inside the source waters to levels that meet up with and usually surpass most Federal and Condition requirements. A Resource Water Assessment Statement for the City of Longmont has been made by the Colorado Division of Public Health and Environment (CDPHE). A duplicate of the report can be acquired by calling 303-651-8416 or by being able to access the SWAP site at source-water-assessment-and-protection-swap. The Source Water Evaluation Report is a screening level evaluation of the probability that a potential contaminant problem could happen, not an indication that potential contamination offers occurred or can occur. The evaluation results are provided like a starting point for general public water systems to judge potential contaminant dangers. The City collects and tests samples of drinking water throughout the watershed within its watershed monitoring program. Monitoring places include reservoirs, St Vrain Creek and portions of the City’s storm drainage program. The watershed monitoring program provides information on Longmont’s water sources and analyzes the quality of water through the watershed. Information on water sources and top watershed can be used to assist with the operation from the City’s water treatment plants to maintain the high-quality drinking water. Longmont is also participating in watershed monitoring that is becoming coordinated by the North Colorado Water Conservancy District (NCWCD) to judge test methods and levels of emerging pollutants such as pharmaceuticals, insect sprays, hormones, etc . within our drinking water sources. More info on the NCWCD research can be obtained from NCWCD at http://www.northernwater. org. WHAT ABOUT BOTTLED WATER? To be able to ensure that tap water is secure to drink, EPA prescribes regulations which limit the number of certain pollutants in water given by Longmont and other general public water systems. Fda (FDA) regulations set up limits for pollutants in bottled water which usually must provide equal protection for public well-being. As noted recently in this report, almost all drinking water, including water in bottles, comes from sources that may contain at a minimum of small amounts of several contaminants. The FOOD AND DRUG ADMINISTRATION limits are intended to offer consumers of water in bottles with the same safety for public health because of other sources of water. However, the rules and testing requirements for contaminants in bottled water are much much less stringent than intended for tap water. More information regarding bottled water, possible pollutants and potential wellness effects can be obtained simply by calling the Environmental Safety Agency’s Safe Drinking Water Servicenummer at 1-800-426- 4791. Another source of info is the Natural Assets Defense Council, that has tested many styles of bottled water. The outcomes of those tests can be found on the internet in stories/truth-about-tap UNIQUE HEALTH CONCERNS Some people might be more vulnerable to pollutants in drinking water compared to the general population. Immuno-compromised persons such as individuals with cancer going through chemotherapy, persons that have undergone organ transplants, people with HIV/AIDS or perhaps other immune system disorders, some elderly, and infants can be especially at risk from attacks. These people should talk to their health care providers. EPA/CDC guidelines on suitable means to lessen the chance of infection by Cryptosporidium and other microbial contaminants are available from the A safe drinking water supply Hotline at 1-800-426-4791. LEAD IN WATER If present, raised levels of lead may cause serious health problems, specifically for pregnant women and young kids. Lead in water is primarily coming from material and parts associated with service lines and home domestic plumbing. The City of Longmont is responsible for providing top quality drinking water, but are not able to control the variety of components used in plumbing parts. When your water continues to be sitting for several several hours, you can minimize the opportunity of lead exposure simply by flushing your faucet for 30 seconds to 2 minutes before using water intended for drinking or cooking food. If you are concerned about business leaders in your water, you might wish to have your drinking water tested. Information on business lead in drinking water, screening methods, and actions you can take to minimize exposure exist from the Safe Drinking Water Servicenummer or at The City’s Drinking water Quality Laboratory, which can be State-certified, performs most of the tests on your water. Contract labs bring tests that the Drinking water Quality Laboratory will not do in-house. 12, 206 tests had been performed on the City’s drinking water last year, 9186 of which were performed by the City’s Drinking water Quality Laboratory. This kind of ensures that the water sent to your tap stands up to the.
