Equine Water Testing

Horse water testing for barns, show facilities and traveling horses. Choose Equine Water Basic for a baseline at one location, or Equine Water Elite to compare two locations.

ReportResults with units, analytical methods and reporting limits where applicableIndividual results, a side-by-side location comparison and a written review of notable differences and potential follow-up testing

Results apply to the submitted samples at the time of collection. These panels do not test for every pathogen or chemical contaminant and do not establish a horse-health diagnosis. They do not include pesticide, PFAS or algal-toxin testing. Review diet- or health-related questions with your veterinarian or equine nutritionist.

Equine Water Basic

Price: $129 per location

Equine Water Basic provides a starting profile of your barn's water supply. It combines bacterial indicators, mineral measurements and core water chemistry in one panel. Use it to establish a baseline or investigate a concern at a single location.

Equine Water Elite

Price: $249 for two locations

Equine Water Elite pairs expanded chemistry with two-location testing. Compare incoming barn water with a trough, bucket or tank to see whether the measured water profile changes before it reaches your horse. For traveling horses, home and event water can be compared when collection and delivery are arranged in advance.

Additional locations, repeat testing and follow-up samples are quoted separately. Sampling labor, site visits and shipping are not included unless specifically stated in the quote.

The written review does not include a veterinary consultation or a guarantee of water safety.

How it's tested

  • Total coliform and E. coli by an enzyme-substrate culture method
  • Nitrate, nitrite, chloride and sulfate by ion chromatography
  • Metals and minerals by elemental analysis
  • pH by electrode
  • Total dissolved solids by gravimetric measurement
  • Hardness calculated from calcium and magnesium
  • Elite adds alkalinity by titration, conductivity by conductivity measurement and turbidity by nephelometry

Sampling

Each location requires its own set of containers. Record the sample location, water treatment and whether the sample came from a tap, tank, trough or bucket.

Getting samples to Vanguard

Request your quote and sample instructions before collecting. Water samples require laboratory-supplied bottles and scheduled delivery. Local customers can arrange drop-off. Shipping is arranged according to the ordered tests, collection time and laboratory receiving schedule. Include your completed submission form and label every sample with its location or lot, collection date and collection time.
