Safety Information


Ash and other products of the fire may irritate your eyes, nose, or skin and cause coughing and other health effects.  Ash inhaled deeply into the lungs may cause asthma attacks and make it difficult to breathe.  People with heart or lung disease, asthma, older adults, children, and pregnant women, should use special caution around ash.  Learn more about how to protect yourself from Ash here.



After a fire, many trees are weakened from burning around the base of the trunk. The trees can fall over or blow down without warning. Shallow-rooted trees can also fall. Please be extremely alert when around burned trees.  More information about hazardous trees can be found here. 


The Environmental Health Division has designed this brochure to help you ensure that your well water is safe to drink. As an owner of private domestic water well that may be damaged by a wildfire, you may have some concerns about fire-related impacts on your well and water system.  Mariposa County Environmental Health recommends the well owner perform a visual inspection of their well and water system, including the piping and plumbing that provide water to and throughout your home. Items that you should check are included in this brochure.


Mariposa Pines has received a Boiled Water Notice. Here are a few things to keep in mind. 

  • There was damage to the main water line that has been repaired. Water is again in the system for homes. 
  • When you return, you should open and run the nearest hose bib to your main water line (where the pipe from the street comes into your house) until any sediment clears. 
  • The system has been shocked to eliminate potential bacteria. 
  • Bottled drinking water is recommended. 
  • If you notice any breaks, signs of damage, or other concerns, let your water company know right away.



Coping with the threat and aftermath of wildfires can cause many strong emotions, including stress and anxiety.
