| Details: | SUMMARY: GWUDI Determination DETAILS: The water system was required to evaluate their well for Groundwater Under the Direct Influence of Surface Water (GWUDI). The water system collected 4 MPA samples and one of the samples scored 27. If one or more risk scores is/are greater than 19, then the water source is classified as under the direct influence of surface water. ACTION NEEDED: In order for the Infiltration Gallery to comply with the SWTR, the following options are available:1. Provide filtration and disinfection treatment as required by OAR 333-61-0032.2. Develop a new source outside the distance-hydrogeologic setting criteria, as outlined in OAR 333-61-0032 (7)(a)(A)(i-v). Wells located outside the distance criteria are typically classified as groundwater.3. Demonstrate that the water produced from the Infiltration Gallery can meet the criteria for exemption from filtration as outlined in OAR 333-61-032 (2) and (3). Meeting the filtration exemption criteria involves continually meeting the source water standards for total and fecal coliform, turbidity, 3-log inactivation of giardia and 4-log inactivation of viruses, 2-log removal of cryptosporidium, and a watershed control program or a certified drinking water protection plan (see OAR 340-040-0160 to 340-040-00180) that addresses both the groundwater and surface water (see in OAR 333-61-032 (2)(c)(B)). 4. Suspend the use of the Infiltration Gallery and purchase water from a nearby approved system. | ||
