Sanford Water District

The Sources The Sanford Water District offers nine sources of the hydrant. All are groundwater resources that draw drinking water from sand and gravel aquifers situated in the City of Sanford. Every source has been delineated to show the area inside the 200 days and 2, 500 day time travel times. These types of areas are demonstrated in the City of Sanford Housing code Ordinance (Article sixteen of Chapter 280-15-1) which is available at the water District. The Area pumps an average of 1 ) 8 million gallons of water each day to meet the water requires of the community. Resource Water Assessment The Maine Department of Human Services Water Program completed a great assessment of the District’s water supply sources included in the Source Water Evaluation Program (SWAP) found in 2003. The water wells received a Modest risk rating depending on the good type and geology from the surficial aquifers. Depending on land use, drinking water tests, land possession, and protection simply by zoning ordinances, the rating for the present protection from contamination is usually Low to Average. The future risk is usually rated Moderate to High. Where possible, the District should think about additional land or perhaps easement acquisition of houses near the wells to lessen the future risk of contaminants. The assessment is usually on file in the District office, Town office and the Condition Drinking Water Program. Treatment The District is constantly on the add hypochlorite in its pumping sites to produce chlorine residuals on sections of the circulation system. Fluorosilicic acidity is added to almost all source water to advertise dental health. Fluoride amounts are maintained among 0. 5 and 1 . 2 mg/L, the optimum level getting 0. 7 mg/L. Sodium hydroxide is usually added to all resources to produce less rust water with a larger pH level. Phosphate is added to Main Station to lessen discoloration caused by flat iron and manganese. Drinking water Quality Testing Considerable sampling programs will be implemented by the Area including the following: • Weekly sampling from the distribution system intended for bacteria, fluoride and chlorine residual • Periodic sampling intended for organic and inorganic parameters in our source drinking water wells • Constant monitoring of ph level levels at the supply pumping stations • Daily monitoring of fluoride, iron, and chlorine residual concentrations at the source moving stations • Particular sampling schedules intended for radionuclides, copper, business lead, and other parameters Regarding Water 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 materials, and can pick up chemicals resulting from the presence of pets or liveliness. 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. Pesticides and herbicides, which might come from a variety of resources such as agriculture, city storm water runoff, and residential uses. Inorganic contaminants, including salts and alloys, which can be naturallyoccurring or perhaps result from urban surprise water runoff, commercial or domestic sewage discharges, oil and gas creation, mining, or farming. Organic chemical pollutants, including synthetic and volatile organic chemical substances, which are byproducts of business processes and petroleum production, and can likewise come from gas stations, city storm water runoff, and septic devices. Radioactive contaminants, which may be naturally-occurring or become the result of oil and gas creation and mining actions..
