Having safe drinking water is critical to maintaining a long and healthy life.<\/p>\n\n\n\n\n\n\n\n<p>The Delaware Public Health Laboratory is certified by the Environmental Protection Agency (EPA), in accordance with the <a href=\"https:\/\/www.epa.gov\/sdwa\"> Safe Drinking Water Act<\/a> to evaluate inorganic and organic contaminants in drinking water from public and private supplies. These supply sources include, but are not limited, to public water systems, restaurants, stores, and private wells. The Environmental Laboratory also evaluates drinking water with the same testing standards from private supplies especially for citizens who obtain their water from a private well.\u00a0<\/p>\n\n\n\n\n\n\n\n<p>The Chemistry Section of the Environmental Laboratory performs laboratory analysis for the detection of over 140 chemical pollutants. This includes, but not limited to, volatile organic compounds (VOCs), disinfection by-products, trace metals, Mercury, anions, routine metals, alkalinity, Total Dissolved Solids (TDS), and conductivity.<\/p>\n\n\n\n\n\n\n\n<p><a href=\"\/wp-content\/uploads\/sites\/10\/dph\/pdf\/watertestperformed.pdf\">Drinking Water Tests at the Delaware Public Health Laboratory<\/a><\/p>\n\n\n\n\n\n\n\n<p>\u00a0<\/p>\n\n\n\n\n\n\n\n<h2>Inorganics<\/h2>\n\n\n\n\n\n\n\n<p>The Chemistry Section provides testing for detection of inorganic compounds by both primary and secondary contaminants could be present in drinking water. This testing can assist in determining the suitability of drinking water for human consumption. The Section utilizes a variety of instruments to perform chemical testing and analysis. A list of the instruments is provided below. These instruments require stringent quality control practices, including calibration, verification, and troubleshooting to properly analyze samples according to the EPA and Standard Methods.<\/p>\n\n\n\n\n\n\n\n<p>\u00a0<\/p>\n\n\n\n\n\n\n\n<div class=\"thumbnail img-responsive pull-right\"><img decoding=\"async\" alt=\"Thermo Scientific HPIC\" src=\"\/wp-content\/uploads\/sites\/10\/dph\/img\/chem_4.jpg\">\n\n\n\n<div class=\"caption smalltext\">Thermo Scientific HPIC (Integrion)<\/div>\n\n\n\n<\/div>\n\n\n\n\n\n\n\n<p><em>Instrumentation<\/em><\/p>\n\n\n\n\n\n\n\n<ul>\n\n\n\n <li>Metrohm Automated Titrator<\/li>\n\n\n\n <li>Shimadzu Atomic Absorption Spectrometer (AA 7000)<\/li>\n\n\n\n <li>Agilent Atomic Absorption Spectrometer (AA-240)<\/li>\n\n\n\n <li>Nippon Mercury Analyzer (RA-4300A)<\/li>\n\n\n\n <li>Perkin Elmer Inductively Coupled Plasma Mass Spectrometer (NexION 350X)<\/li>\n\n\n\n <li>Thermo Scientific Ion Chromatography (Integrion)<\/li>\n\n\n\n<\/ul>\n\n\n\n\n\n\n\n<h2>Organics<\/h2>\n\n\n\n\n\n\n\n<p>The Chemistry Section also provides testing for primary, regulated and unregulated organic contaminants in drinking water that could potentially be a health risk for humans if consumed. Examples of common organic contaminants are chloroforms and Haloacetic acids.
