<p>France's Gard department has allowed Nestle to continue using two wells for Perrier production with new conditions. Nestle must submit a study on the filtration method's impact on the water's microbiome within 12 months and conduct enhanced safety checks for two years. Three other wells are no longer permitted for use. This follows scrutiny over illegal water treatments, leading Nestle to adopt microfiltration.</p>
