Private wells in Ottawa County
In 2015 about 74,986 of Ottawa County’s 279,955 residents (27%) got their drinking water from a private well, by the USGS estimate. That is the 67th highest share of the 83 Michigan counties in the USGS table, and the 6th highest number of private-well users.
This rule covers the well as well as the septic system. USGS models about 3,052 private-well users in Ottawa County with arsenic above 10 µg/L, EPA’s limit for public water (2010 population base; 95% range 2,387 to 3,884), the 24th highest of 82 Michigan counties. It is a screening estimate, not a result for any one well.
Source: USGS county water use 2015 (Dieter et al., 2018); USGS domestic-well arsenic estimate (Ayotte, Medalie and Qi, 2017). Ranks count the Michigan counties in the USGS table (1 = highest).
Soils and septic systems here
USDA soil surveys rate 98% of Ottawa County’s rated land “very limited” for a conventional septic drain field, 2% “somewhat limited” and 0% “not limited”, the 33rd highest “very limited” share of 78 Michigan counties with survey data. The most common limits: a high water table (saturated soil near the surface) on 70%; fast seepage below the field (risk to groundwater) on 54%; slow percolation (dense or clay soil) on 51%.
Where soils are limited, inspections more often find drain fields that sit in seasonally wet soil, and replacement systems are often mounds or other engineered designs. A county-wide rating, not a test of one lot: a site evaluation decides.
