MUHONEN PROPERTY WELL RADIUS EVALUATION

Plateau Geoscience Group conducted an evaluation of the offsite portion of the domestic well radius at the Muhonen property in Ridgefield, Washington. Clark County Environmental Health Department requires a 100-foot radius setback for domestic wells, and where this radius may be located offsite and evaluation of potential for well contamination must be made. Current conditions and site use, as well as historic site use, area geology, and hydrology were evaluated with respect for potential for well contamination. The well radius evaluation concluded that the onsite domestic well is not likely to become contaminated based on absence of nearby surface water, or by historic, current or future anticipated offsite land uses.
