Any combination of analytes below can be tested as well as many not mentioned. Contact us with your desired suite for pricing. These suites represent our most commonly analyzed packages. These analysis suites are shown for your convenience, but may not be adequate depending on your specific situation.

ContaminantWhich wells or homes should be tested?How often should I test?
Coliform BacteriaAll wellsTest annually, or when there is a change in taste, color or odor.
NitrateAll newly constructed wells with no testing history

Wells within 1/4 mile of fertilized fields or animal feed lots
Two tests spaced six months apart

Test annually
PesticidesWells within 1/4 mile of agricultural fields, pesticide manufacturing,
storage or mixing facilities
Test once every 5-10 years
LeadHomes with copper plumbing installed before 1985 or brass fixtures
and naturally soft water
Test once
BTEX/TPHWater with an oily sheen or petroleum odor, or if you are located close
to any gas drilling operations
Test once
Arsenic/SeleniumAny well located in the Four Corners region and many other parts of ColoradoTest once
CopperIf water is used to prepare infant formula or if any resident in the home
experiences repeated symptoms of nausea, diarrhea or abdominal cramps
Test if symptoms indicate possible contamination
VOCsWells within 1/4 mile of a landfill, underground fuel or gasoline tank and
wells within 1/4 mile of where solvents have been used (drycleaners, automotive
garages, or body shops, etc. )
Test once every 5 to 10 years or when solvent or gasoline taste or odor is noticed
RadonHomes with high radon levels in the air that are not reduced by mediation
Test once if needed
FluorideWells used by infants and preschool age children

Any well located in the Four Corners region and many other parts of Colorado
Test when infant is born

Test once if needed
Chloride, Sodium,
Barium, and Strontium
Wells near gas drilling operationsTest once if needed
Hydrogen Sulfide GasIf your water has a rotten egg smellTest once if needed
Iron & ManganeseBoth cause staining and/or bitter tasteTest once if needed
HardnessLarge amounts of hardness will cause a residue on dishes and faucets, and over time can cause damage to plumbingTest as needed
BART Bacteria TestIRB (Iron Related Bacteria): Red, brown or yellow water; Iron flocs may form

SRB (Sulfate Reducing Bacteria): Blackened water; rotten egg smell

SLYM (Slyme Forming Bacteria): Cloudy water, slimy residue
Test as needed
RSK-175Used to determine the presence of dissolved gases, such as Methane, in
Test as needed

Package #1: General Water Quality

This package provides information relative to the basic mineral content of surface and ground waters. It can be used to assess common water issues, but does not address some long-term human health hazards.

Tests: pH / Conductivity, Total Dissolved Solids, Alkalinity, Hardness, Chloride, Fluoride, Sulfate, Calcium, Magnesium, Potassium, Sodium, and Iron

Package #2: Safe Drinking Water Act Inorganic Chemistry Parameters

This package targets many low level human health concerns.

Tests: Antimony, Arsenic, Barium, Beryllium, Cadmium, Chromium, Copper, Lead, Nickel, Selenium, Sodium, Thallium, Mercury, Fluoride, Sulfate, Nitrate/Nitrite

Package #3

This package contains some from both Package 1 and 2. It is not as complete as a package 1 + 2 and bacteria, but offers the most commonly seen problematic parameters from above.

Tests: Arsenic, Calcium, Fluoride, Chloride, Hardness, Iron, Lead, Magnesium, Manganese, Nitrate/Nitrite, pH, Selenium, Sodium, Sulfate, TDS, Total Coliform and E.Coli.

La Plata County Planning Engineering Package

This suite is used by the county to address common ground water usability. If you have been issued a “La Plata County Planning Engineering Form –Water Quality Testing Results”, this is the package you need.

Tests: Antimony, Arsenic, Barium, Beryllium, Cadmium, Chromium, Copper, Fluoride, Lead, Mercury, Nitrate, Nitrite, Selenium, Thallium, Total Coliform and E. Coli.

Prospective Home Buyers

Many government based lenders (VA, FHA) require private water wells to be tested as part of a home loan or refinancing. The exact details of what is required to confirm that the water is acceptable are a bit unclear. If no local guidelines exist, the minimum testing requirements that we have seen referenced are Lead, Nitrate, Nitrite, Total Coliform and E. Coli.

Note: In many government loan situations, it is required to have a third party collect the water sample to be tested.

Oil and Gas

GAL has over 25 years of experience serving the oil and gas industry, in both Colorado and New Mexico.

Surface, pit and groundwater monitoring
Baseline and cleanup confirmation
Hazardous waste analysis for disposal
Rush Spill Assessments
Table 910, Rule 608 & 609

Soil Testing

GAL offers many analyses that can be used to determine soil deficiencies or contamination. Some of the tests include, but are not limited to: Chloride, Sulfate, Nitrate/Nitrite, TKN, pH, Conductivity, Exchangeable Cations, Sodium Adsorption Ratio (SAR), Texture, Neutralization Potential, Potassium or Phosphate Available, Total Sulfur, and metals.

Possible additions to Package #1 Or #2

Total Coliform and E.Coli presence/absence bacterial testing.

(BTEX) Benzene, toluene, ethyl-benzene, and xylene: This is the least expensive organic hazards option and contains the most commonly seen hydrocarbon contaminates.

(VOCs) Volatile Organic Compounds: Full list including BTEX and many other organic, industrial contaminates. Does not include SOCs such as Pesticides and PCBs.

(RadChem) Basic Radioactive Chemistry: Includes Gross A/B particles, Radium 226/228, and Uranium.
