Nearest Intake

Highlight 8-32, page 263 of the HRS Guidance Manual provides numbers, like 82,500, that are well worth remembering. These numbers are used in all pathways, with one exception: for the soil exposure pathway the minimum value for quantity never rises above 10.

Apply the 50, 45, or 20 and dilution weight sequentially:

  • 50, if any intake is subject to level I

  • 45, if no Level I, but an intake is subject to Level II; and

  • 20 and dilution weight if no intakes are subject to actual contamination.

Standby intakes may be considered for this factor only if they are used for supply at least once a year. Note the similarity of "nearest well" in the ground water pathway.
