Well BG = Background well; Conv'l = Conventional septic system, Dosing =
Conventional system with a pump chamber and dosing system, and Mound = Mound-
type system.
Sites with available wells were sampled October 26 & 29-31, 1993.
Total Kjeldahl Nitrogen (TKN) was determined using the semimicro Kjeldahl procedure
of Bremner and Keeney (1966) with 5 mL of effluent or 20 mL of groundwater per
sample.
