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.
- 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 Biochemical Oxygen Demand)
- Wastewater Complete. Includes 5-day Biological Oxygen Demand (BOD5), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), pH, Electrical Conductivity (EC), Nitrate, TKN, Total Nitrogen, Phosphorus, Chloride, and Fecal Coliforms.
- Nutrient Monitoring. Includes Nitrate/Nitrite, Total Kjeldahl Nitrogen (TKN), Total Nitrogen, Total Phosphorus, Ortho Phosphorus, pH, Conductivity, TDS, SAR, Calcium (Ca), Magnesium (Mg), and Sodium (Na).
- 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).
- 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), Ammonia, pH, and Electrical Conductivity (EC). More information about this test below.
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. 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), Slime forming bacteria (SFB), Total Solids, TSS, TDS, pH, EC, BOD5, CBOD5, dissolved oxygen (DO), Alkalinity, Hardness, SAR, and anything else found in our services and pricing guide.
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 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, 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 Nutrient Monitoring package. For soil, our routine package includes everything you should need (Wyoming Nutrient Technical Standards). Our basic manure package covers everything except ammonia which Wyoming requires for all liquid manures.
Nebraska – Department of Environmental Quality (DEQ) Title 130, Chapter 14. For water we recommend our Nutrient Monitoring package.
Kansas – KDHE-Livestock Waste Management Section. For water we recommend our Nutrient Monitoring package. For soil our routine package should include everything you need (Kansas Natural Resources Conservation Service – 590). All manure and fertilizer requires ammonia testing in Kansas which is included in our complete manure 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.
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.
