It can also come from materials in contact with water (MCDE).<\/p>\n<p>According to the order of 11 January 2007, total chromium must be tested for at the resource for surface-origin water (RS Programme) and at the consumer&#8217;s tap (D2 Programme).<\/p>\n<p>A quality limit for total chromium is set at 50\u00b5g\/L in raw water used for the production of drinking water and in distributed water.<\/p>\n<p>Regulations do not set specific limits for chromium VI, however the ARS may request additional analyses for this parameter, at the expense of the person responsible for water production or distribution (PRPDE).<\/p>\n<p>The toxicity of chromium VI is considered more concerning than that of chromium III. ANSES has estimated a maximum concentration of chromium VI at 6\u00b5g\/L<\/p>\n<p>Despite the absence of regulations on chromium VI, this instruction defines the actions to be taken in case of presence of chromium in drinking water in order to take into account the health risk associated with the presence of chromium VI:<\/p>\n<ul>\n<li>If total chromium is &gt; 50\u00b5g\/L, the result must be confirmed by a new analysis, together with a chromium speciation analysis to determine the quantity of hexavalent chromium.<\/li>\n<li>If total chromium is &gt; 6\u00b5g\/L, a second analysis must be carried out along with chromium speciation.<\/li>\n<li>When the chromium VI concentration is &gt; 6\u00b5g\/L, the result must be confirmed by a new analysis.<\/li>\n<\/ul>\n<p>Chromium VI analysis must be carried out by an approved laboratory with a maximum limit of quantification of 5 \u03bcg\/L (and if possible lower than 2 \u03bcg\/L).<\/p>\n<p>In case of chronic exceedance of the quality limit for total chromium and\/or the maximum concentration defined by ANSES for chromium VI, the ARS, together with the PRPDE, must implement the actions below:<\/p>\n<ul>\n<li>If the total chromium concentration is &gt; 50\u00b5g\/L, the population must be informed by the PRPDE not to use the mains water.<\/li>\n<li>Whether the total chromium concentration is &lt; or &gt; 50\u00b5g\/L, if the chromium VI concentration is &gt; 6\u00b5g\/L, the population must be informed by the PRPDE not to use the mains water.<\/li>\n<li>The PRPDE must conduct an investigation to determine the origin of this contamination and implement corrective actions.<\/li>\n<li>Health checks on these two parameters must be strengthened.<\/li>\n<\/ul>\n<p>In case of a one-off exceedance not confirmed by the second analysis for chromium VI, it is recommended to monitor chromium VI in addition to total chromium as part of the health monitoring.<\/p>\n<p>Phytocontrol is approved by the Ministry of Health for sampling and health control analyses of water. We are approved and accredited for chromium VI analysis with a limit of quantification of 2\u00b5g\/L as part of our E2 approval \u2013 Optional chemical analyses.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Ministry of Solidarity and Health published on 15 September 2019 a technical instruction DGS\/EA4\/2019\/142&hellip;<\/p>\n","protected":false},"author":8,"featured_media":10608,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[181],"tags":[],"class_list":["post-10618","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-regulatory-watch"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.4 (Yoast SEO v28.5) -
