Any downgradient domestic or municipal drinking water well that has <br />a confirmed VOC detection at a concentration greater than its MCL <br />shall be immediately supplied with replacement drinking water at no <br />cost to the landowner, unless the City of Stockton is already providing <br />such a supply. <br />d. By 30 April 2009, the Discharger shall submit a report of sampling results to <br />Central Valley Water Board, the landowner/well user, and to the San Joaquin <br />County Environmental Health Department.
