<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Well water tests from October 19, 1998 to May 20, 2019 conducted by the NC Department of Health and Human Services (NC DHHS) State Laboratory for Public Health were compiled. These data underwent quality assessment and control protocols, and were geocoded resulting in a dataset of n=117,960 well water test reports, spanning all 100 counties and 89% of census tracts. County-level and census tract-level descriptive statistics and number (and percentage) of exceedances of federal and state standards were calculated for 28 different metals/metalloids. The included metals/metalloids are: aluminum, antimony, arsenic, barium, beryllium, boron, cadmium, calcium, chromium, cobalt, copper, hexavalent chromium, iron, lead, magnesium, manganese, mercury, molybdenum, nickel, potassium, selenium, silver, sodium, strontium, thallium, uranium, vanadium' .
