Wastewater

We have a full suite of wastewater packages available to meet the requirements of your permit. We also have Nutrient Monitoring packages for your Nutrient Management Plans and specialty packages for your Lagoon.

  1. Wastewater Basic. Includes 5-day Biological Oxygen Demand (BOD5), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), pH, Electrical Conductivity (EC). (Optionally substitute BOD5 for 5-day Carbonaceous Biological Oxygen Deman)
  2. Total Nutrient Monitoring. Includes Total Nitrogen (TN), Total Inorganic Nitrogen (TIN), Total Nitrate-Nitrite Nitrogen (by cadmium reduction), Ammonia Nitrogen (NH3-N), Total Kjeldahl Nitrogen (TKN), and Colorimetric Total Phosphorus (TP).
  3. Inorganic Nutrient Monitoring. Includes Total Inorganic Nitrogen (TIN), Total Nitrate-Nitrite Nitrogen (by cadmium reduction), Ammonia Nitrogen (NH3-N), and Colorimetric Total Phosphorus (TP).
  4. Surface Water Discharge Basic. Includes pH, Total Dissolved Solids (TDS), Electrical Conductivity (EC), Total Suspended Solids (TSS), 5-day BOD, Fecal Coliform Bacteria (F. Coli), Oil and Grease (visual).
  5. Surface Water Discharge Complete. Includes Temperature*, Dissolved Oxygen (DO), pH, Total Dissolved Solids (TDS), Electrical Conductivity (EC), Total Suspended Solids (TSS), 5-day BOD, Fecal Coliforms (F. Coli), Oil and Grease (visual), Oil and Grease (gravimetric). E. Coli.*, Residual Chlorine (TRC)*, Sulfates (SO4), Sulfide as H2S, Chloride, Copper, Iron, Zinc, Manganese, Calcium, Magnesium, Sodium, Hardness (as CaCO3) . Some NPDES permits also require the Total Nutrient Monitoring package above and the RCRA metals package below.
  6. RCRA metals. The Resource Conservation and Recovery Act (RCRA) defines eight toxic metals (RCRA8) which must be carefully monitored. This package includes Arsenic (As), Barium (Ba), Cadmium (Cd), Chromium (Cr), Lead (Pb), Mercury (Hg), Selenium (Se), and Silver (Ag).
  7. Lagoon Complete. Includes dissolved oxygen, 5-day Biological Oxygen Demand (BOD5), soluble BOD5, 5-day Carbonaceous Biological Oxygen Demand (cBOD5), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), pH, Electrical Conductivity (EC). Most of our lagoon customers also add the Total Nutrient Monitoring package as well.

Weld Laboratories offers a full range of testing to meet many needs of customers who have monitoring requirements outlined in a National Pollution Discharge Elimination System (NPDES) permit.  Surface Water Discharge packages can also be used for ground water discharge or land application in many cases. We are happy to provide a custom quote based on your specific requirements. Contact us for more information.

Note: We can add any of the following analyses a-la-carte to the packages above: Sulfide (H2S), Chloride (Cl), Fecal Coliforms (F. Coli), Total Coliforms (T. Coli), Iron reducing bacteris (IRB), Sulfur reducing bacteria (SRB), Total Solids, TSS, TDS, pH, EC, BOD5, CBOD5, dissolved oxygen (DO), Alkalinity, Hardness, SAR, and anything else found in our services and pricing guide. *Residual chlorine has a very short holding time of 15 minutes. The laboratory must be notified prior to delivering these samples. If you are not able to deliver the samples in time we advise that you order a residual chlorine test kit. E. Coli bacterial analyses have a 24 hr holding time; samples must arrive cooled at 1-4°C for delivery to a contract laboratory.

 

Nutrient management plans

Why are Nutrient Management Plans (NMP) slowly becoming requirements? If nitrogen and phosphorus flow in excess they can become pollutants. More information about nutrient pollution is available from the EPA: nutrient pollution.

Different states have different requirements for nutrient monitoring. Whether you are a small farm or operate a concentrated animal feeding operation (CAFO) we have a plan for you! We are one of only a few laboratories in the country equipped for every facet of your Nutrient Management Plan. We test your soil, manure, and lagoon water to determine your levels. If we need to probe deeper we can examine your harvested plant tissue as well.

Colorado – Regulation 85. For water we recommend our Total Nutrient Monitoring package. Colorado Nutrient Management Standards. Your Colorado NMP should include: 1) for soil our routine package, 2) for manure our basic manure package, and 3) for fertilizer our NPK package. There are no plant tissue requirements in Colorado.

Wyoming – Department of Environmental Quality (DEQ) Numeric Nutrient Criteria. For water we recommend our Inorganic Nutrient Monitoring package.

Nebraska – Department of Environmental Quality (DEQ) Title 130, Chapter 14. For water we recommend our Total Nutrient Monitoring package.

Kansas – KDHE-Livestock Waste Management Section. For water we recommend our Total Nutrient Monitoring package.

Surface Water Discharge Information

Industries that discharge wastewater to surface or groundwater are governed by the NPDES a division of the EPA. The methods used to test wastewater and other pollutants fall under 40 CFR, Part 136. We work with everything from construction dewatering permits to point source permits. We can provide a custom quote for the monitoring requirements in your permit. Contact us for more information.

Lagoon Troubleshooting

In Colorado, lagoon effluents are frequently out of compliance for a number of reasons. 67% of the violations are due to algae overgrowth, 10% are due to problems with nitrification. Dr. Michael Richard from the Sear-Brown group published an impressive guide to using TSS/BOD5 ratios, dissolved oxygen, and cBOD5 to “troubleshoot” your lagoon. We built our Lagoon complete package to help facilitate this analysis.
