schedules will always have an initial start date of either January 1st or July 1st and the biweekly compliance periods will follow that initial begin date.\u00a0 Therefore, water systems cannot schedule samples to be collected on the same days of each month (e.g. 1st and 15th).\u00a0 Water systems need to be mindful when scheduling sampling, especially those systems with a seasonal source (biweekly compliance periods start with the initial date of the monitoring schedule, not the start of the seasonal operational period).<\/p>\n<h3>The documents below list the bi-weekly monitoring
