R 560.414 Primary maximum contaminant levels.

Rule 414. (1) The department shall reject proposed development sites that are less than 1 acre in size and subdivisions if the water sample analysis detects contaminants in concentrations that exceed the primary maximum contaminant levels as defined in R 560.401(t). (2) The department shall reject proposed development sites that are less than 1 acre in size and subdivisions if the water sample analysis detects a contaminant in a concentration that is more than 50% of the maximum contaminant level and the department has determined that the contaminant is likely to exceed the primary maximum contaminant level in the future after considering the following: (a) Contaminant transport and modeling. (b) Land use. (c) Geology. (d) Other factors that influence groundwater movement. (3) If the department requires additional analysis under R 560.412(4), then the department shall use the drinking water regulations and health advisories adopted in R 560.413 to determine primary maximum contaminant levels.
