Section Env-Wq 808.02 - Groundwater Monitoring Plan Requirements(a) The applicant shall submit a groundwater monitoring plan that identifies: (1) The constituents to be monitored;(2) The location and identification of all sampling points;(3) The sampling frequency;(4) The sampling methodologies;(5) The analytical methodologies; and(6) The procedures that will be used to establish background concentrations of all constituents required to be monitored. "Background concentrations" means concentrations detected in areas unaffected by the site or facility permitted or to be permitted.(b) In addition to (a), above, the applicant shall include the following on the site or facility plan prepared in accordance with Env-Wq 806.06 or Env-Wq 807.06, respectively: (1) The location, elevation, and datum of a bench mark, if a survey is conducted to establish topography;(2) Ground surface spot elevations and contours to show topography, using information from the most recent USGS map or more accurate information, if available;(3) The identification and location of existing and proposed groundwater monitoring wells, showing at least one hydraulically up-gradient and 2 hydraulically down-gradient wells;(4) The identification and location of any surface water sampling points;(5) Groundwater contours that accurately show groundwater flow direction;(6) A description of the method used to develop groundwater contours, including the identification and location of any piezometers;(7) A table of water level measurements and elevations found in any piezometers and monitoring wells used to develop the groundwater contours;(8) Well construction details of any existing monitoring wells, top of well casing elevations, and measured depth to water table from top of casing; and(9) Well construction details of any proposed monitoring wells in accordance with Env-Wq 402.N.H. Admin. Code § Env-Wq 808.02
