Flood & environmental risk
Johnston County has experienced 10 federally declared disasters since 2005. Flooding and severe storms can overwhelm water treatment plants, cause sewage overflows, and introduce agricultural runoff, bacteria, and sediment into drinking water supplies. Local water sources include Neuse River, Little River, Contentnea Creek.
Where does Micro's water come from?
Micro's drinking water comes from groundwater (wells), supplied by 3 water systems serving approximately 657 people. Groundwater is generally less susceptible to surface contamination but can contain naturally occurring contaminants like arsenic, radon, and nitrate. Nearby water bodies include Neuse River (river), Little River (river), Contentnea Creek (river).
What Micro residents can do
Recommended: NSF-certified water filter. This addresses the specific contaminants found in Micro's water.
Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.
Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.
Micro's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.
