Typically undeveloped land is of low concern for soil or groundwater contamination. Note the gas station in this photo, however. Soil contamination is unlikely at this site but groundwater contamination may be an issue if there was a leaking tank at the gas station. Presence of a leaky tank is easily determined by examining records of the facility, reviewing MPCA's on-line tool, or noting the presence of groundwater monitoring wells. If a leak existed at the site, groundwater flow should be determined. This can be obtained either from information collected at the gas station site or, if they exist, from local groundwater flow maps. If the site is upgradient of the gas station, determine if mounding beneath the proposed infiltration practice will intersect the contaminant plume. If the site is downgradient of the gas station, determine if the contaminant plume extends beneath the site.
