The other group of people who are more sensitive to the effects of mercury are fetuses during their development.&nbsp; Mercury can adversely affect the growth of brain and nervous system of a baby which can result in the impairment of his/her cognitive thinking, memory, language, fine motor and visual spatial skills.</p><p>Because mercury is ubiquitous in our environment, it poses a real challenge to maintain a clean environment.&nbsp; As a result, a lot of states' permits increasingly require compliance to a lower water effluent limit for mercury.&nbsp; The low-level mercury method provides an ability to assess compliance with mercury water quality standards below 0.2 ug/L.&nbsp; Additionally, in accordance with the Clean Water Act (CWA), the permit requires the surface water discharge to be analyzed using a sufficiently sensitive method so that reasonable assurance can be provided to prevent the future will be not violated.&nbsp; CWA also requires NPDES (National Pollutant Discharge Elimination System) permits to include effluent limitations that are as stringent as necessary to meet water quality standards.&nbsp; Over the past few years, we have seen more and more of our clients switch to low level mercury testing from traditional high-level mercury analysis.</p><p>Ana-Lab adopted EPA Method 245.7 for analysis of low level mercury with a detection limit of 0.6 ng/L, which is close to the minimum quantization limit of EPA Method 1631E (0.5 ng/L). As a result, our low-level mercury analysis will satisfy the requirements for EPA 1631E.</p><p>When using low-level mercury analysis, clean sample handling techniques should be applied to sample collection to preclude the sample contamination.&nbsp; It is also recommended to collect at least one blank at each site when the sample is collected. The blank may either be an equipment blank or a field blank. Field blanks should be collected only if no equipment other than the sample container is used to collect samples.&nbsp; If the sampling procedure involves using additional equipment, such as a pump and pump tubing, an equipment blank should be collected.</p><p>For additional information about sample collection, bottle requirements, and analysis, please do not hesitate to contact us so that we may assist you.</p><p align="center"><br></p><p>&nbsp;</p> Wed, 11 Jul 2018 05:00:00 +0000 http://ana-lab.com/blog/post/are-nonylphenols-cause-for-concern Are Nonylphenols Cause for Concern? http://ana-lab.com/blog/post/are-nonylphenols-cause-for-concern <p>Nonylphenols (NPs), from its name you can guess it is a phenol that has a nine-carbon chain attached to it.&nbsp; Therefore, NPs are a family of alkylphenol and the alkyl chain can be attached to any position of the phenol.&nbsp; Among all the isomers, a branched 4-nonylphenol is the most widely used NP.&nbsp; The largest industry application for 4-NP is in the manufacture of nonionic surfactants due to the stability, excellent wetting, emulsifying property of 4-nonylphenol ethoxylate (4-NPE).&nbsp; Those nonionic surfactants have been used in commercial and household cleaning products, such as detergents, shampoos, lotions, liquid cosmetics.&nbsp; The other area of their application includes used as antioxidant, corrosion inhibitors, pesticides, chemical and heat stabilizers.&nbsp;&nbsp; </p><p>&nbsp;</p><p>NPs are known to be very toxic to wildlife, particularly aquatic organisms.&nbsp; Like well-publicized bisphenol A, NPs exhibit estrogenic effects in the body.&nbsp; This type of compound is classified as an endocrine disruptor which usually functions by mimicking hormone through its binding with an estrogen receptor and acting competitively against natural estrogen.&nbsp; NP's hormone-like effect was first discovered by accident when it was found that existence of NP contaminated the experiment results conducted with natural estrogen. The subsequent researches have shown NPs can displace the estrogen in a fish from its receptor.&nbsp; Male fish exposed to NPs has resulted in lower testicular weight. The other effects of NPs include feminization of fish, reduction of male fertility.&nbsp;&nbsp; </p><p>&nbsp;</p><p>Due to their physical–chemical characteristics, such as low solubility and high hydrophobicity, NPs accumulate in environmental compartments.&nbsp; NPEs degrade into NPs when they reach sewage treatment facilities.&nbsp; Besides of sewage sludge, NPs are also found in other matrices such as effluents from sewage treatment, river water and sediments, soil and groundwater.&nbsp; Because many NPs containing products used for cleaning have down-the-drain application, they are handily and frequently introduced into the water supply.&nbsp;&nbsp; NPs are however not readily biodegradable. Their half-lives in sediment are estimated to be more than 60 years.&nbsp; So, the sewage sludge if being recycled into agricultural land will result in contamination to the crops from which they are grown.&nbsp; NPs' other environmental impacts include feminization of aquatic organisms, decrease in male fertility and the survival of juveniles at a concentration as low as 8.2 μg/l.&nbsp; Due to their harmful effects, the use and production of NPs have been banned in EU countries and strictly monitored in many other countries such as Canada and Japan.&nbsp; In 2005, EPA set Ambient Water Quality Criteria (AWQC) for NPs for fresh water (FW) and salt water (SW) as below:</p><p>&nbsp;</p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; AWQC, FW&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; one-hour average&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 28 ug/L</p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;AWQC, FW&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; four-day average&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 6.6 ug/L</p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;AWQC, SW&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; one-hour average&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 7&nbsp;&nbsp; ug/L</p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;AWQC, SW&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; four-day average&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.7 ug/L</p><p>&nbsp;</p><p>These criteria are not to be exceeded more than once every 3 years.</p><p>&nbsp;</p><p>In 2014, EPA proposed a significant new use rule (SNUR) that will require the manufacturer to submit to EPA for review whenever the use of any of the 15 NPs and/or NPEs is started or resumed.</p><p>&nbsp;</p><p>In our lab, we have developed a method using GC-MS to analyze NP with a detection limit of 2.22 ug/L.&nbsp; <strong><u>We are among the few labs with the capability to test this parameter</u></strong>.&nbsp; If you have any questions about this testing, please feel free to contact us.</p> Wed, 30 May 2018 05:00:00 +0000 http://ana-lab.com/blog/post/water-quality-parameters-wqps Water Quality Parameters (WQPs) http://ana-lab.com/blog/post/water-quality-parameters-wqps <p><br></p><p align="center" style="text-align: left;">In my blog post several weeks ago, I wrote about the Lead Copper Rule (LCR). I mentioned that from time to time, the metals can leak from water pipes or fixtures into the water system by corrosion. The corrosion is a process through which metal has oxidized to form a cation. The cation is water soluble thus it can migrate from the metal surfaces into water. Most of metals can be corroded to some degree which takes place in the same way as to how a battery functions when two different metals are connected through a media called electrolyte. However, the rate and extent of the corrosion depends on the metal, media and environment. In the case of a water system, the corrosion can be affected by the following conditions:</p><p> </p><p>1. pH. Either low pH or high pH can both cause corrosion. At a low pH, the water is acidic under which most of the metals whose redox potentials are low can be oxidized. At a high pH, the water may become vulnerable to bacteria (such as sulfur reducing bacteria) induced corrosion.</p><p> </p><p>2. Dissolved solid (TDS). The water that has low TDS is called soft water. The corrosion can occur in soft water due to lack of dissolved cations, such as calcium and magnesium in the water because the presence of those minerals tends to form a coating on the metal surface thus slowing down the dissolution of the metal from metal pipe. Water contains a high level of TDS when there is large amount of sodium, chloride or other ions present. High TDS water means it has high conductivity thus promoting corrosivity.</p><p> </p><p>3. Chloride to Sulfate. The mass ration of two (CSMR) along with alkalinity is related to galvanic corrosion. An elevated CSMR can increase the potential for galvanic corrosion of water system. In fact, research conducted by Dr. Edwards from Virginia Tech concluded that it was a change of CSMR ratio that caused the deterioration of metal corrosion in the Flint water crisis. Prior to water crisis, the city of Flint, Michigan had switched water treatment materials from sulfate-based aluminum to chloride based in order to save money.</p><p> </p><p>Under Lead Copper Rule (LCR), the parameters like pH, conductivity, ion concentrations, and TDS are used to evaluate the quality of the water flowing through the distribution system. TCEQ requires all Public Water Systems (PWS's) with a population over 50,000, new PWS's of all population and any PWS's that have exceeded the action levels (0.015 mg/L for lead and 1.3 mg/L for copper) to test for the water quality parameters (WQPs). Orthophosphate is a common chemical used as an inhibitor for water treatment. If it is used for water treatment, it is also required to be included in the testing of WQP.</p><p> </p><p>In compliance with LCR, TCEQ published public water system guidance in terms of how to do monitoring and sampling for WQP testing. TCEQ will use WQP results to evaluate if drinking water is corrosive and determine effectiveness of the water treatment program in order to prevent corrosion. </p><p> </p><p>The info about WQP can be found on the TCEQ website at:</p><p><a href="https://www.tceq.texas.gov/drinkingwater/chemicals/lead_copper/lead-copper.html"><u>https://www.tceq.texas.gov/drinkingwater/chemicals/lead_copper/lead-copper.html</u></a></p><p> </p><p>1.

Because of the presence of organic fluorine, it renders the surface of the pan a unique property, such as water and oil repellant.&nbsp; </p><p>Perfluorooctanoic acid (PFOA), also known as C8, is an essential processing aid during the production of the above-mentioned fluoropolymers.&nbsp; Besides this application, PFOA has also been widely used in other industrial products, such as carpets, leathers, textiles, paper packaging, etc.&nbsp; The existence of PFOA in the environment is mainly from discharge of waste water in a manufacturing plant of fluoropolymers.&nbsp; PFOA can also be generated from the degradation of precursors of fluoropolymers.&nbsp; Surface and ground water susceptible to PFOA contamination could become a concern due to the use by other industries and product disposal from municipal and industrial waste sites.&nbsp; </p><p>PFOA is a highly stable compound due to the strong carbon-fluorine bond.&nbsp; This stability is desirable as a product but is a cause of environmental concern because of its resistance from degradation by natural processes such as metabolism, hydrolysis, photolysis or bio-degradation resulting in its longer lifetime in the environment.&nbsp; Historically, PFOA has been reported in waste water, soils and bio-solids.&nbsp; The research on PFOA has demonstrated its toxicity for animals and some associations with human health parameters and potential health effects such as kidney and testicular cancer, thyroid disease, high cholesterol, etc.&nbsp; </p><p>The EPA began requiring public water systems (PWS's) to monitor PFOA and Perfluorooctanoic Sulfonate (PFOS) in 2012 under the Third Unregulated Contaminant Monitoring Rule (UCMR 3).&nbsp; The Safe Drinking Water Act (SDWA) amended in 1996 requires EPA issue a new list of no more than 30 unregulated contaminants to be monitored by PWS's every five years.&nbsp; In 2016, the EPA published drinking water health advisories for PFOA and PFOS to assist federal and state drinking water systems in protecting public health when the chemicals are present in drinking water.&nbsp; The levels of PFOA and PFOS concentration under which adverse health effects are not anticipated to occur over a lifetime of exposure are 0.07ppb.&nbsp;&nbsp; In 2016, the Environmental Working Group (EWG) has published an analysis based on the monitoring reports submitted to EPA covering 5,000 PWS's in 45 states and the district of Columbia.&nbsp; The finding from this analysis indicated the presence of unsafe levels of PFOA in about 0.3 % of PWS’s.</p><h5><strong>Concerned about PFOA and PFOS?

The accumulative scientific studies have demonstrated even low-level lead exposure over a period of time can cause adverse health effects on adults and typically children. </p><p> </p><p>Why is lead hazardous to the human body? The main reason is attributed to its similarity to calcium, a building block for human bone. Lead, when being dissolved, can replace and function as calcium. Because of this, the research indicated over 90% of lead in the human body is stored in bone. The stored lead in bone can migrate into blood during the period of heightened bone turnover, such as pregnancy when lead is released from bones as maternal calcium and transferred through the blood stream to the fetus to help the bones formation. </p><p> </p><p>In serious cases this can reduce the growth of the fetus and result in premature birth. Due to similar effects, lead is more harmful to infants and young children than adults. The studies have shown even low levels of lead in children can cause heath issues, such as behavioral and learning problems; lower IQ and hyperactivity, etc. </p><p> </p><p>How lead can get into drinking water? It is through corroded service pipes and fixtures. Homes built before 1986 are more likely to have lead pipes, fixtures and solder which can leak lead into the water system by corrosion. To address the corrosion issue of lead and copper into drinking water, in 1991 the Environmental Protection Agency (EPA) issued the Lead Copper Rule (LCR) under the authority of the Safe Drinking Water Act (SDWA). The regulation was revised in 2000 and 2007. EPA delegates primary enforcement responsibility (also called primacy) for public water systems (PWSs) to states and tribes if they meet certain requirements.</p><p> </p><p>In light of a very publicized Flint water crisis, the EPA has requested that states take action to ensure LCR is being properly implemented. Texas achieved final primacy approval for the LCR Minor Revisions in 2006 and LCR Short Term Revision in 2012. On behalf of the state of Texas, Texas Commission on Environmental Quality (TCEQ) is responsible for overseeing the program that ensures production, treatment, delivery and protection of safe and adequate drinking water to the public. </p><p> </p><p>TCEQ has required the community and non-transient non-community PWSs in Texas to monitor LCR starting from 2016 to ensure the LCR and primacy requirements are implemented. The protocols and procedures that TCEQ uses for implementing the LCR are consistent with EPA's guidelines and are shown from the link below:</p><p> </p><p> <u><a href="https://www.tceq.texas.gov/drinkingwater/chemicals/lead_copper" rel="nofollow">https://www.tceq.texas.gov/drinkingwater/chemicals/lead_copper</a></u></p><p> </p><p> </p><p><b>The requirements for sampling (when and how many) are listed below:</b></p><p> </p><p> </p><table border="0" cellspacing="0" cellpadding="0"> <tbody> <tr> <td width="188"> <p>System Size</p> <p>(number of people served)</p> </td> <td width="190"> <p>Number of sites for</p> <p>Initial/Routine monitoring</p> </td> <td width="287"> <p>Number of sites for Reduced monitoring:</p> <p>1YR, 3YR, or 9YR</p> </td> </tr> <tr> <td width="188"> <p>More than 100,000</p> </td> <td width="190"> <p>100</p> </td> <td width="287"> <p>50</p> </td> </tr> <tr> <td width="188"> <p>10,001 to 100,000</p> </td> <td width="190"> <p>60</p> </td> <td width="287"> <p>30</p> </td> </tr> <tr> <td width="188"> <p>3,301 to 10,000</p> </td> <td width="190"> <p>40</p> </td> <td width="287"> <p>20</p> </td> </tr> <tr> <td width="188"> <p>501 to 3,300</p> </td> <td width="190"> <p>20</p> </td> <td width="287"> <p>10</p> </td> </tr> <tr> <td width="188"> <p>101 to 500</p> </td> <td width="190"> <p>10</p> </td> <td width="287"> <p>5</p> </td> </tr> <tr> <td width="188"> <p>100 or fewer</p> </td> <td width="190"> <p>5</p> </td> <td width="287"> <p>5</p> </td> </tr> </tbody></table><p> </p><p> </p><p><strong>Initial Sampling</strong>: Systems must complete two (2) rounds of consecutive six-month sampling.

Ms. Holyfield is Team Leader for Responsible Care and Compliance at Eastman.</p><p>“The workshop is designed to help 6<sup style="font-weight: lighter;">th</sup> through 12<sup style="font-weight: lighter;">th</sup> grade Texas educators learn about the importance of the chemical industry, as well as provide them with a balanced view of environmental issues and workforce opportunities in the industry,” Ms. Holyfield explained. “It also gives them activities related to chemistry that they can take back to their classrooms.”</p><p>The Ana-Lab portion of the four-day event was on Thursday and included lab tours and a catered lunch.&nbsp; The teachers and other guests were divided into three tour groups led by Ana-Lab employees.</p><p>Following the Ana-Lab lab tours and lunch, participants engaged in a question-and-answer session.&nbsp; “This was another group of strong, committed educators,” said Robyn Irving, Dir. of Communications for Ana-Lab Corp.&nbsp; “I appreciated their level of enthusiasm, and I thanked them for their commitment to the teaching profession.&nbsp; In my view, we can never thank teachers enough.”&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</p><p>Dr. Aaron Gardner, a secondary science teacher from Jacksonville ISD, said he gleaned a lot during the four-day event.&nbsp; “I enjoyed the hands-on projects, as well as the field trips to Eastman, Flint Hills, the landfill, and Ana-Lab,” Dr. Gardner said.&nbsp; “I learned some new aspects of chemistry and how it is used on a daily basis.&nbsp; This has been a very fascinating and educational experience.”</p><p>Dana Hill, a chemistry teacher from Harmony ISD, was also enthusiastic.&nbsp; “I really enjoyed seeing the application of what is taught in the classroom in a ‘real world’ setting.&nbsp; Seeing the lab operations and the use of equipment and science skills will help me answer that burning student question of ‘So when am I ever going to use this?’,” she said.</p><p>A New Diana teacher, Jeff Barrett, added, “It was great talking with the employees at the toured businesses.&nbsp; It will help me guide students who are interested in pursuing careers in the chemical industry.”</p><p>“As an educator, we don’t always experience the ‘real world’ application,” said Summer Willis of Cumberland Academy in Tyler.&nbsp; “Seeing all the opportunities for our students has been enlightening.&nbsp; It was also refreshing to see local people with varying levels of education being utilized.”</p><p>“This has been an excellent in-service,” said Loren Lykins of Carlisle ISD.&nbsp; “We’ve had great tours of production, manufacturing, and laboratory facilities, as well as informative presentations and hands-on activities provided by knowledgeable presenters.”</p><p>Teachers who completed the full four days will receive 27 hours of continuing education credit, Ms. Holyfield noted.&nbsp; Districts represented were Alba-Golden, Beckville, Carlisle, Cumberland Academy, Cushing, Harleton, Harmony, Hawkins, Henderson, Jacksonville, Kilgore, Longview, Marshall, Martinsville, Mineola, Nacogdoches, New Diana, New Summerfield, Pine Tree, Sabine, San Augustine, West Rusk, West Sabine, and Westwood.</p><p>“This year’s workshop has been very well received by the teachers,” Ms. Holyfield said. “I think the tours were especially impactful as the teachers could see the chemical industry and labs in person and talk to their employees about what they do.&nbsp; The teachers can now go back to their students and give them ideas about local career opportunities, many of which require only a two-year degree.”</p><p>“I’d like to thank the participating businesses for their help, and especially the staff at Region 7 ESC for once again doing an incredible job of hosting us at their conference center,” Ms. Holyfield added.</p><p><br></p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</p> Fri, 21 Jul 2017 05:00:00 +0000 http://ana-lab.com/blog/post/ana-lab-gives-5000-grants-to-two-cities Ana-Lab Gives $5,000 Grants to Two Cities http://ana-lab.com/blog/post/ana-lab-gives-5000-grants-to-two-cities <!--StartFragment--><p>Two East Texas cities – Carthage and Maud – have each received a monetary award from Ana-Lab Corporation of Kilgore.
