I wanted to ask on what I should do if a home has well water with a high level of bacteria and arsenic.

I recently read that the CDC said masks are a detriment (build up of spores, fungi and bacteria) unless it is washed daily and I know for sure most people don't wash their masks every day.

Weak link in the plumbing... it's probably not the actual toilet. 1. put 1/4 cup baking soda in toilet bowls and sinks 2. then a cup of vinegar, it will bubble, let it sit an hourflush, rinse sinks with two cups more or less of boiling waterThis should cut out the bacteria high up in the drains for a couple weeks.I would give the tenant a big box of baking soda and walmart gallon bottle of vinegar and notsend a plumber.

It's porous so it can stain easily and trap bacteria and has to be resealed every year or two.

Flood waters are full of every bad thing you can imagine - bacteria, sewage, farm manure, chemicals, oil...

However, my house is on a short, dead end street with only two other houses and a mobile home; there's no city sewer line available and no plans to put one in in the near future so nothing to "tie into".At this point my goal is to limit the number of people living in the house (to reduce the sewer "load"), provide them with products containing bacteria to flush down the toilet once a month (no guarantee they'll do that), include a clause in their lease to limit the use of bleach and ammonia that would kill the bacteria in the tank and a regular (once a year) clean out of the tank.Gail

Have the bacteria, nitrates, etc. tested.  

Linoleum is made of renewable ingredients, naturally resists bacteria and moulds, it durable and the colour usually permeates through the material.   

Bacteria are eating the iron and the by product is a rotten sulfur smell.
