Step 1 of 5
How much does your dog weigh?
Larger dogs produce up to 4x more urine per day than small dogs. Weight is the #1 driver of turf contamination.
Merck Veterinary Manual
How many dogs use your turf?
Each additional dog compounds contamination exponentially. Two dogs don't double the problem, they multiply it.
How old is your turf?
Uric acid crystals from dog urine permanently bind to infill fibers over time. No amount of hosing removes them. Age is a one-way clock.
PMC Artificial Turf Microbiota Research
Do you notice odor on hot Las Vegas mornings?
Odor means bacteria are actively producing ammonia gas. You're smelling a live contamination event, not old residue. Las Vegas turf surfaces reach 169°F, accelerating this reaction.
UNLV/Desert Research Institute Study
Does your dog use your turf for solid waste, and how quickly is it removed?
Fecal matter contains up to 23 million fecal coliform bacteria per gram. These organisms concentrate in the infill layer where heat, UV, and rinsing have limited reach.

When DIY isn't enough
How is this calculated?

Your score reflects both the urine contamination factors and, if applicable, the solid waste frequency you reported.

Your score combines five things you told us: your dog's size, how many dogs you have, how old your turf is, how often you notice odor, and whether your dog uses the turf for solid waste. Each one nudges the score up based on how much it's known to drive contamination.

  • Dog size — bigger dogs produce more urine per day (Merck Veterinary Manual: 20–40 mL per kg body weight, per day).
  • Number of dogs — total volume scales with each dog.
  • Turf age — uric acid crystals bind to the infill and accumulate over time. Water doesn't dissolve them.
  • Odor frequency — active odor signals bacterial activity is already happening below the surface.

What this score is: a directional estimate. A higher score means a higher probability your turf has meaningful contamination, based on the factors above and what's known about how Las Vegas heat affects bacterial activity in synthetic infill.

What this score is not: a lab measurement. The only way to know the actual bacterial load in your specific yard is an ATP bacteria test, which samples the surface and measures live microbial activity in RLU. We include ATP testing with our Renewed Grove service.

Based on: Merck Veterinary Manual (urine output, 20–40 mL/kg/day); U.S. EPA Clean Water Campaign (fecal coliform, 23 million bacteria/gram of dog waste); UNLV/DRI Artificial Turf Temperature Study (2007); Valeriani et al. 2019, PMC6728760 (artificial turf microbiota); Penn State CSSR (bacterial survival on synthetic turf)
