The Indiana Department of Environmental Management (IDEM) visited the residence of Hopf Environmental's founder Andy Hopf on October 9th, 2014 to collect a ground water sample to add data to the Statewide Ground Water Monitoring Network.  Hopf's drinking water well qualified for the program because the water well record was properly filed and mapped with the Indiana Department of Natural Resources (IDNR).  I say properly, because many residential drinking water wells, were either not logged and/or submitted to the state, as required by law.  The well was installed in 1988, long before Hopf bought the residence so  it is fortunate that the well driller filed the paperwork properly.  To check and see if your or your neighbors water well is logged, visit the IDNR water well web viewer.  

The IDEM Ground Water Section began sampling wells annually across the state in 2008 to comply with Section 305(b) of the Clean Water Act, which requires states to assess ground water quality.   Samples are analyzed for over 400 constituents including the National Drinking Water Contaminants, and un-regulated pesticide breakdown products.  The National Drinking Water Contaminants include volatile organic compounds (VOCs), synthetic organic compounds, and inorganic compounds. 

Date from ground water samples across Indiana have nitrates, arsenic, and pesticide breakdown products present at quantities above IDEM's residential tap water screening levels.  Nitrates and pesticide breakdown products are associated with agricultural and horticultural practices.  Arsenic's source is most likely natural and from shale bedrock and soil found in parts of Indiana.  

Analytical data from the sample IDEM collected is valued at over $1,000 for the laboratory analysis alone.  Additional costs to the state include labor and equipment.  Needless to say, thank you IDEM for sampling my well!
