Hi there, I my opinion the biggest sources of bacterial pollution are failing septic systems and pet wastes. In rural areas, you can usually add livestock waste. In some areas, wildlife contributes their own pollution. Each year, health inspectors focus on a handful of watersheds in Kitsap County. The fact that local waters are growing cleaner in the face of expanding development must be testimony to their success.

Hi there, in my judgment Ceramic tiles are made from refined clay and other material. Maintenance is important through routine cleaning with mild soap and water. If you have some stains to remove, try a few of these suggestions to get your tile looking new again.
1. Clean the stained area with plain water and a soft cloth. Dry thoroughly.
2. Put on gloves. Use these to protect your hands even if the product is considered natural or non-toxic.
3. Mix borax and lemon juice together on a disposable plate or bowl. The consistency should be a paste-like substance. Rub onto the stain and allow it to dry completely. Rinse the ceramic tile with water and repeat until stain is gone.
4. Use a mixture of a vinegar and salt to make a paste. Apply to the rust stain and wait 4 to 5 hours and then rinse with hot water. Repeat as necessary.
5. Consider purchasing a Lustrous Italian cleaning kit. Apply to area with a moistened, soft cloth. This Lustrous Italian will remove the stain and not scratch surfaces.
