Once your order has been prepared for shipment and ships, you will receive a Shipment Notification email with carrier and tracking information.
Shipping and Delivery Estimates
The 'Ships' timeframe is an estimate of when the item will ship from our warehouse. All items will ship at one time unless you specifically request partial shipment. In which case, the items on your order will ship as they become available. The 'Delivers' timeframe is an estimate of when the item will be delivered to your shipping address after it ships. The estimated delivery time depends on the shipping method you choose during checkout. All estimates are based on business days.

Fondriest offers several convenient shipping options via UPS.
Ground Shipping: | Products shipped via ground service are normally delivered within five business days after shipment. |
2-Day Shipping: | For an additional charge, Fondriest offers 2-day shipping for most products. Products shipped via two-day service prior to 4:00 p.m. EST are normally delivered by 7:00 p.m. local time two business days after shipment. |

Remember that these estimates are for time in transit only, and that they do not apply until the product leaves the Fondriest warehouse. As the delivery of your order is beyond Fondriest's control once your order leaves the Fondriest warehouse, we cannot assume liability for late deliveries, regardless of the delivery method you specify.
Signature Required on Most Deliveries
Most of Fondriest's shipments contain valuable equipment. If you will not be at the shipping address to accept delivery of your product, consider shipping the item to an address where someone you trust will be available to sign for your package, or accept your package if a signature is not required for the delivery. Once your order has prepared for shipment or has shipped, we are unable to change the shipping address. Title and risk of loss to all products will pass to you on delivery. If you are willing to assume the risks of delivering your order without a signature, you may authorize Fondriest to arrange for a delivery that does not require anyone to be at the delivery address.
Undeliverable Packages
Occasionally packages are returned to Fondriest as undeliverable. When the carrier returns an undeliverable package to Fondriest, please contact us to make arrangements for reshipment.
Failed Delivery Attempts
Most of Fondriest carriers make three attempts to deliver a package. After three delivery attempts, the carrier will return the package to Fondriest.
Order Processing
The estimated shipment date on your order is based on product availability, payment processing time, and warehouse processing time and does not include transit time. We do not begin payment processing until Fondriest receives all of the information that is needed and full payment or a full authorization, in the case of credit card or rental orders.
Fondriest will begin payment processing for orders placed on weekends or holidays on the next business day. Business days are Monday through Friday, excluding federal holidays.
Your order for in-stock items that are eligible for same-day shipping must be received before your local time of 2:00 p.m., pending payment processing, for there to be adequate remaining time in the day for your order to be dispatched.
Product Availability
Fondriest makes every effort to ship your product according to the estimated lead times. The estimated lead times are in business days (Monday through Friday, excluding federal holidays).
Although Fondriest makes every effort to ship your order according to the lead time provided, shipping dates may change due to changes in supply. If the lead time changes, Fondriest will contact you via email and provide a revised shipping estimate.
Fondriest makes every effort to supply the products you order, but there may be occasions when Fondriest confirms orders and later learns that it cannot supply the products, either at all or in the quantities ordered. Although rare, these occasions can include when Fondriest learns that the products no longer are being manufactured or they otherwise become unavailable, when Fondriest cannot source components for the configuration you ordered, or when there was a pricing error at the Fondriest Online Store.

Source Water Monitoring in Albany, New York: Tracing Water Quality throughout Tributaries
Thousands of US cities pull their drinking water from natural source waters like reservoirs, rivers, and streams, making overall watershed health a key consideration for water providers. In Albany, New York, the Albany Department of Water and Water Supply delivers drinking water to over 100,000 residents as well as monitors and manages the larger drinking water supply watershed. Hannah Doherty, Environmental Specialist at the Albany Department of Water and Water Supply , spends her days working with a small team to monitor the drinking supply and the connected water bodies. Doherty explains, “We’re the first to encounter the water that ends up being the drinking water.

Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question. [caption id="attachment_38996" align="alignnone" width="940"] HRWC volunteers measure stream velocity across a subsection of Woods Creek, a tributary of the Huron River near Belleville, Michigan. Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.
